KOLBENMOTOR

A piston engine designed as a motor with a star configuration has a rotary shaft arranged in the motor housing, upon which pistons linked to a piston rod are radially movable. An expanding gaseous fluid exerts a pressure on the pistons that are arranged each in a working chamber located in the motor housing. The successive working chambers and pistons generally have a wedge-shaped cross-section, and the number of working chambers and pistons is variable. The pistons are radially movable in the rotor, in the direction of rotation, and operationally coupled to a forced control. The object of this invention is to obtain a specific power as high as possible with a compact design and a reduced engine weight. Among many others, its most remarkable characteristic is the extremely high motor torque that results from this motor system. With this engine an engine torque that is 48 times higher than that of comparable 4-stroke internal combustion engines is obtained, thanks to the 24-fold reduction ...

IMPROVED RADIAL CAM INTERNAL COMBUSTION ENGINE

Embodiments of the present invention include a radial cam, internal combustion engine. The cam assembly, which is centrally located inside an engine block, has two-lobes and four raceways. Four cam-following bearings engage with the cam assembly's four offset raceways and are connected to the piston via a connecting rod. The connecting rod's movement is confined by a guide-way system which transmits the lateral forces placed on the cam-following bearings back to the engine block via a removable guide-plate. The connecting rods move the engine's pistons inside a plurality of cylinder barrels, which are dispersed in opposing pairs radially around the cam assembly.

Crankless external combustion engine

An external combustion engine 1, engine comprising cylinder 3, a piston 2 reciprocally mounted within the cylinder, a connecting rod 9 extending from the piston and two spaced-apart rollers 5, 6 mounted on the connecting rod, wherein a first one of the rollers is adapted to engage primary cam(s) 7 means and a second one of the rollers is adapted to engage secondary cam(s) 8 means, the primary and secondary cam means being affixed to, and rotatable with, a common output shaft 4. In a conventional crank the piston movement is sinusoidal and the power and exhaust stroke are identical. Greater efficiencies can be achieved by shortening the exhaust cycle and lengthening the power cycle, accelerating the piston to optimised velocities during the power stroke to allow further heat and energy transfer and decreasing the time when the piston passes the exhaust and inlet ports.

Ring cam ensuring smooth follower handover between segments

A ring cam for a fluid-working machine comprises plural segments 5, 7 having piston facing surfaces 15, 16 together defining a working surface. The segments comprise leading and trailing end cooperating formations each having a potion of the working surface, which each inter-engage with respective adjacent formations and which are recessed from the working surface towards their respective ends or cross at less than 180 degrees. The cooperating formations interlock and rollers are thereby handed over smoothly from one segment to the next irrespective of slight variations in alignment due to manufacturing tolerance or wear. The segment piston facing surfaces are placed in compressive stress to partially or fully compensate for tensile stress arising from the action of rollers in use. The segments form a wavelike cam surface and attachment means 3 are provided, through the working surface on whichever of the leading 70 or trailing 72 surfaces thereof is subject to lowest forces from pistons in use.

REVERSIBLE COMPRESSED AIR MOTOR

In reversible compressed air rotary motors for compressed air tools, particularly for wrenches, it is known to discharge the waste air radially from the casing of the motor, which results in a considerable nuisance, in particular as regards noise. Furthermore, due to the close positioning of the compressed air inlet and air outlet, poor efficiency is achieved. To avoid those drawbacks in a rotary sliding vane motor having an elliptical working chamber, the rotor end over on the inlet side is rotatably mounted, and air outlet means is arranged axially and lies in both the clockwise as well as in the antic-clockwise direction or rotation of the rotor relative to the major semi-axis of the elliptical working chamber. Thus by rotating the end cover to one or other of its limit positions, the outlet means communicate with different pairs of passageways.

It relates to a two-stroke rotary engine in which the engine body, that is, the cylinder and the crankcase, rotate in such a manner as to engage around a fixed fixed gear and transmit it to the output shaft with reduced rotational force. 본 발명은 출력축을 중심으로 모든 부분이 대칭 운동을 함으로서 회전 무게 중심이 항상 일정하여 진동이 적고, 종래의 왕복엔진에서 회전을 안정되게 하기 위해 부착하던 벨런싱 웨이트나 플라이휠과 같은 중량체가 없더라도 안정된 회전력을 얻을 수 있으며, 고속으로 분출되는 베기 가스의 힘을 회전력으로 첨가할 수 있고, 크랭크축에서 발생된 고속 회전력이 감속되어 출력 축에 전달됨으로 실용 회전수에 가까운 출력이 발생된다. 따라서, 경량이면서 고출력, 고효율, 저 진동의 엔진을 얻을 수 있게 된다. 본 발명은 자동차, 발전기, 선박 또는 기타 원동기용 엔진으로 사용될 수 있지만 출력축과 일체로 된 엔진 본체 즉, 중량체인 실린더와 크랭크케이스 및 크랭크축, 커넥팅로드, 피스톤이 회전됨으로서 원심력이 증가하는 자이로 효과로 헬리콥터의 엔진에 보다 효과적으로 적용될 수 있는 2행정 로우터리 엔진에 관한 것이다. According to the present invention, all parts are symmetrically moved around the output shaft, so that the rotational center of gravity is always constant so that the vibration is low, and even in the conventional reciprocating engine, even if there is no weight body such as a balancing weight or a flywheel, the stable rotational force is achieved. It is possible to obtain, and the force of the cutting gas ejected at high speed can be added as the rotational force, and the high-speed rotational force generated in the crankshaft is decelerated and transmitted to the output shaft, thereby generating an output close to the practical rotational speed. Therefore, a lightweight, high output, high efficiency, low vibration engine can be obtained. The present invention can be used as an ...

Radial cylinder machine.

La machine à cylindres radiaux décrite comprend un certain nombre d'arbres à ailettes équidistants (7) qui effectuent un mouvement orbital autour de l'axe central de la machine vers l'intérieur des pistons (13). Les arbres à ailettes (70) tournent également autour de leurs axes respectifs grâce à des pignons planétaires placés sur chaque arbre (7) qui s'engrènent avec une couronne de train planétaire fixe. Les lobes à mouvement orbital et rotatif (9) servent de cames pour les faces intérieures des pistons (13), ce qui permet une conversion entre le mouvement alternatif des pistons (13) et le mouvement rotatif des arbres à ailettes (7). Les arbres à ailettes (7) sont montés sur un support fixé à un arbre d'entrée/sortie à axe central, ce qui assure un transfert du couple, permettant ainsi à la machine de fonctionner comme un moteur ou comme une pompe. Un organe, servant à maintenir le contact entre les pistons (13) et les ailettes (9), est également décrit. The described radial cylinder machine comprises a number of equidistant finned shafts (7) which perform an orbital movement around the central axis of the machine towards the inside of the pistons (13). The fin shafts (70) also rotate around their respective axes by means of planetary gears placed on each shaft (7) which mesh with a fixed planetary gear ring. The orbital and rotary movement lobes (9) serve as cams for the inner faces of the pistons (13), which allows conversion between the reciprocating movement of the pistons (13) and the rotary movement of the fin shafts (7). The fin shafts (7) are mounted on a support fixed to an input / output shaft with a central axis, which ensures a transfer of the torque, thus allowing the machine to function as a motor or as a pump. A member, used to maintain contact between the pistons (13) and the fins (9), is also described.

Patent FR2376944B3

Rotary cylinder hydraulic pump or motor - has regulating disc to vary through put short circuiting several cylinders

The machine has a shaft (2) carrying a rotor (3) which contains several radial cylinders (4) in each of which a piston (5) reciprocates. The outer end of each piston carries rollers (16) which run on guide rings (8a, 8b) on the inside of the casing (7) and have recesses to give the pistons a reciprocating motion. Fluid enters through a channel (37) and a groove (39) to an aperture (41) in each recess in the guide rings. It leaves the recesses through apertures (44, 44a) in alternate recesses which connect with grooves (42, 42a) leading to a discharge channel (38). A disc (46) can be moved to close one set of release apertures (44a) so that no pumping or driving action takes place in the recesses connected to these apertures. The disc is controlled by a servomechanism.

Patent FR2142294A5

Radial piston hydraulic pump or motor - has cylindrical sleeve around spherical piston to give good sealing with low weight

The machine has a rotor (11) turning on a stationary hub (10). Radial cylinders (12) in the rotor run in succession over ports, from inlet and discharge passages (13, 14) in the stub. Pistons in the cylinders press with their outer ends on the inside of a stator case (20) which is eccentric to the rotor to produce the reciprocation. The pistons are formed by balls (16) held in cylindrical sleeves (17). The balls provide rolling contact on the stator whilst the sleeves provide surface contact between the piston and cylinder to give a good seal. The radial length (H) of the sleeve is less than the dia. (D) of the ball.

Patent FR2275640B1

Rotary internal combustion engine

This engine includes an engine block rotatably mounted on a support and including a central chamber communicating with outwardly protruding radial piston chambers closed by cylinder heads. A crank shaft is rotatably mounted in the engine block parallel to the rotation axis of the latter and radially offset therefrom. A drive train couples the engine block with the crank shaft for causing rotation of the two in the same direction and at equal rotational speed. A piston is reciprocable in each piston chamber and all the pistons are linked by connecting rods to the crank shaft at connecting points which are angularly advanced in the direction of rotation of the engine block relative to the longitudinal axes of the piston chambers. It follows that the combustion stroke is effected while the connecting rods exert a maximal torque on the crank shaft.

Hydraulic motor - with radially moving piston cylinder units and a valve system surrounding the shaft

Hydraulic motor with a first unit attached to a shaft (11) with a number of radially operating piston cylinder units (17, 18, 19). There is a second unit (13) with at least one cam guide (15, 16) against which the piston cylinder units (17, 18, 19) press whilst under pressure in order to produce a relative turning movement between the first and the second unit (12 or 13). A valve system (30) surrounding the shaft (11) is fitted close to the first unit (12) to supply pressure liquid to the inlet of each piston cylinder unit. The valve system is fixed relative to the second unit so that the first unit is turnable relative to the valve system. A pressure device is fitted on the shaft retains the valve system against the first unit in an axial direction. The first unit and the valve system work together with the pressure device so that the forces separating the first unit and the valve system can be transmitted to the shaft and produce a force countering the separating movement on the shaft.
