Rotary engine

In a stator formed of two toric cylinders there rotate two rotors fixed to a drive shaft and each equipped with two pistons arranged so that the crown of one piston of the first cylinder faces the crown of a piston of the second cylinder. Each cylinder includes, on one side, an external compression chamber and, on the other, an intake and exhaust zone, both equipped with valves which, opening upon the passage of each piston, close off the cylinders by abutting against bearing bushes formed by the flaring of the cylinders at this point. The compression valve of each cylinder is kept closed by the rim of its rotor whereas, via a set of non-return valves, its chamber is filled with air compressed by the following piston in the other cylinder, and so on from one cylinder to the other. The intake and exhaust valves open upon the passage of the pistons via the action of springs. All the valves close again under the pressure of air formed by the arrival of the following piston.

Improvement to encapsulated engines

Rotary internal combustion engine consisting of two annular chambers in which there move two pistons 2a and 2b connected by thin sections to one same driveshaft 3. These pistons, in rotating, on the one hand cause the volumes of the chambers defined by the casing and the sliding stoppers 4a, 4b, 4c and 4d to vary and, on the other hand, in a sealed manner block off the ports in front of which they pass. The first torus is the compressor stage, the second the drive stage, combustion taking place alternately in the chambers 5a and 5b. The stoppers permanently follow the profile of the pistons, and separate each annular space which has been left free by the piston into two enclosures which are sealed with respect to one another.

Patent FR2146526A5

Rotary internal combustion engine - has two elliptical rotors within a circular cylindrical stator

The engine has a circular cylindrical stator (ST) one end of which contains a elliptical rotor (RM) which leaves working chambers (C, C1) between itself and the stator varying in volume as the rotor turns. Radially sliding vanes in the stator divide each chamber into two compartments. Combustion takes place in recessed pockets (C4, C5, C6, C7) in the stator from which the gases pass to the working chambers for expansion and exhaust strokes. There is another elliptical rotor on the same shaft at the other end of the stator which forms working chambers in which the admission and compression strokes take place.

ROTARY MOTOR

Positive displacement fluid machine

The drive shaft (1) has two rotors (2,3) rotating in separate elliptical chambers formed by the stators (12,13) and a central partition (11). Each rotor has (P) of sliding blades in continuous contact with the stators. The optimum angular relationship (8opt) between the blades of one rotor relative to the other is determined by the formula delta opt = Pi/P, for an even number of blades and delta opt = Pi/2p for an odd number of blades.

ROTARY MOTOR

Pressure-fluid-driven machine

Rotary engine

The invention relates to a rotary engine which is suitable for use as a spark ignition or diesel engine or as a steam engine. The gas chambers required for this, the volumes of which must constantly vary with the rotation of the rotor, are produced by the interaction of at least two pairs of sealing slides, of which at least one pair can make way for the other. In addition a separate combustion chamber is necessary. A continuous rotary movement is produced without external mechanisms. <IMAGE>

The rotary engine has toroidal working chambers, where an outer chamber is formed from an intermediate ring-upper part (10), an intermediate ring-lower part and an outer ring (9). The inner chamber is formed from an inner ring (12) that is concentrically arranged to the outer ring. The rotation force-transmission is possible between the outer ring and inner ring by fluid-mechanically connected boreholes in a transmission part.

Rotary piston internal combustion engine

Rotary piston engine for motor vehicle

The engine comprises a compressor block (1) connected to a working block (2) by a combustion chamber block (8) onto which a combustion chamber (9) is mounted. There are sealing gaps (17,18) between the peripheries of the compressor rotor (4) or the working rotor (6) and the inner wall of their respective housings (3,5). The compressor and expansion areas are separated from the combustion chamber. There are movable sliders (12,13) guided in the compressor and working housings. The sliders are formed as stoppers which slide in each housing, contacting the rotors to form a suction chamber (19), compression (20), expansion (21) and exhaust (22) chambers. The stoppers oscillate under radial pressure.

Counter-rotating pump of simple design, high pressure and output and not comprising any friction or reciprocating movement, which can be reversed at any instant by simply reversing the direction of rotation

This design of pump has the feature of being very simple in operation, using only rotary movements. Theoretically there is no internal wear. Its output and its pressure are high for a small external bulk. It is reversible by simply reversing its direction of rotation. This pump implements the opposite rotation of two rotors which simultaneously create, during their movement, a suction chamber and a delivery chamber. The field of application of this pump is vast. It may of course replace numerous current pumps, but it may also operate as a compressor or internal combustion engine (disregarding the problems of sealing) or as a turbine or heat pump. A last field of application may be medical if it proves to have better performance than current artificial hearts.

Rotary piston internal combustion engine

A rotary piston internal combustion engine with two counter-rotating pistons (14, 15) located on the same axis and engaging with one another. One of the pistons acts as a compression or charging piston and the other as an expansion or propulsion piston. The design is aimed at providing a favourable co-ordination between the charging piston and the propulsion piston with the operating chamber of the propulsion piston being several times that of the charging piston, and is such that the two rotary pistons, whilst maintaining conjugate peripheral angles of approximately 360o, possess different peripheral lengths which leave in the rotary piston paths, operating chambers of different sizes, which take into account a pressure increase between the inlet air and the combustion gas.

Internal combustion turbine with endless effect piston

Improvements made to a rotary internal combustion engine which gives it a turbine behaviour and allows it to be much economical, much smaller, much lighter and nonpolluting. In addition, these improvements mean that the piston of this engine receives a continuous thrust during its entire rotation, and that it is almost as powerful at altitude in a rarer atmosphere as on the ground in an atmosphere of normal density. It is therefore very suitable, due to its smallness, its aerodynamic shape and its low consumption, for propelling flying craft. Here, for example, the engine 1 rotates the compressor of a jet engine and a propeller, which gives it dual propulsion, using a propeller and a jet, and where one can become aware of the smallness of the engine with respect to the propeller, and its aerodynamic nature.
