Groove Trap Apparatus for Combustion and Compression Machinery

A combustion system and apparatus is disclosed. The apparatus employs a groove-shaped combustion area and a trap composed of a lid and a door. The lid is disposed in communication with the trap and is configured to slide within and over the groove-shaped combustion area during use. Combustion occurs within the groove-shaped combustion area, pushing the trap, whereby a rotor is forced to rotate, conveying power from a combustible material to perform work. As a corollary, the apparatus may be configured for use in the field of air compression and air decompression. Multiple groove-shaped combustion areas may be configured in a parallel or series orientation. Gas compression/decompression only utilizes a single groove, whereas combustion preferably utilizes a compression groove and a combustion groove.

The rotor is mounted in the cylindrical casing. The spring loaded inlet valve is actuated by the cam through the push rod. As the space in the rotor passes the inlet valve, a fuel-air mixture is drawn into the engine. The sliding vave seals the space so that the mixture is compressed into the chamber. As the rotor continues to rotate the space comes in line with the chamber when the charge is ignited by the sparking plug. The increase in pressure due to the explosion exerts a resultant force to maintain the rotation of the rotor.

Compressor or pump with eccentric rotary piston - has vane slot in cylinder running completely through housing

The machine has a casing (1) with a cylindrical bore (2) within which a circular cylindrical piston (9) revolves eccentrically. The piston touches the cylinder bore at one point (8) and a vane (3) sliding in a radial slot (10) in the cylinder casing presses on the piston between the inlet and discharge ports (4, 5). The space between the piston and cylinder is thus divided into two variable vlume chambers (6, 7). The slot (10) for the vane runs completely through the casing from the inside to the outside along the whole length of the cylinder. Dowels (15) in the casing (1) on either side of the slot fit recesses in the end pieces and thus locate the sides of the slot to fix its width.

Rotary vane device e.g. high output rotary vane-type air motor, for e.g. transferring motive power for low pressure fluid, has rotor comprising openings, where distance between openings is variable based on rotation position

The device has a hollow cylindrical body (1) designed as a chamber of an engine, where a rotor (2) is axially inserted into the chamber. The rotor is integrally formed of pallets (3). Another rotor i.e. drum rotor, comprises openings for moving the pallets. The openings define active volume of a sector-shaped chamber, where the volume increases on either side of an inlet (13) and an outlet (14). The latter rotor is made of articulated elements in a telescopic manner. Distance between the openings is angularly variable according to rotation position.

Hydraulic motor with oval rotor in circular cylinder - has throttling passages between high and low pressure sides

The motor has a circular cylinder within which is a rotor which has opposed ends on a major diameter and sections between them of a smaller diameter. The cylinder has inlet and discharge passages leading from inlet and discharge ports. The gap between the reduced diameter of the rotor and the cylinder forms the working chambers.

The vane members extend radially outwardly of the rotor and in pressure sealing relationship with the channel while being rotated through the channel by the rotor to pump fluid from the inlet passage to the outlet passage. The cavity also includes a circumferential wall portion between the outlet passage and the inlet passage over which the rotor passes with the vane members retracted within the rotor. A circumferential groove extending in the circumferential wall portion provides communication between radial openings simultaneously passing the wall portion to relieve pressure therein and to thereby facilitate radial movement of the vane members.

Machine with rotary piston including a flexible annular member

A fluid driving or fluid driven machine includes an outer cylinder housing stationary piston. The piston includes a generally annular flexible band of smaller circumference than the inner circumference of the cylinder, and a rotary body accommodated within the band. The rotary body has three rollers for urging the band against the inner surface of the cylinder at three angularly spaced locations so that the band defines with the cylinder three working chambers. Two separating members mounted on the cylinder are biased into contact with the band. When the rotary body is rotated the band makes nonslip contact with the wall and rotates the working chambers about the axis of the rotary body. Each separating member separates each working chamber as it passes into two discrete enclosures. A port is located on each side of each separating member to allow communication with the two discrete enclosures. The machine can be operated as a compressor when the rotary body is driven or as an engine to drive the rotary body.

Rotary piston I.C. engine - has circular stator with radial vanes and eccentric rotor with output shaft

The rotating piston engine has a circular stator chamber within which rotates a circular rotor type piston about its eccentric axis, and can work as a two or four stroke engine. The stator chamber has slots for radial vanes whose ends are in contact with the rim of the rotating piston. The eccentric rotor diameter is such that the distance between the centre of the eccentric shaft and the remotest point of the rotor rim is slightly smaller than the radius of the chamber. The distance from the shaft centre of the nearest point of the rotor rim is not greater than half of the chamber radius. Hence the rotor does not contact the chamber walls. The radial vanes are constantly in contact with the rotor rim and variable volume pockets are generated on rotating between the vanes and the chamber and rotor walls.

Internal-combustion engine

A rotary engine comprises a circular rotor surrounded by an annular stator. The rotor is provided around its outer circumference with spaced combustion chambers and with recesses therebetween. Each recess serves as an expansion chamber for a jet of gas produced by combustion in an associated combustion chamber. Each recess is also provided, remote from the associated combustion chamber, with a cam. The stator at its inner circumference has retractible reaction members which are movable into the recesses to be acted on by the gas jet so as to create forces acting in opposite sense on the rotor and stator and thus cause the rotor to rotate. The reaction members have deflector surfaces arranged to deflect the gas jet in such a manner that the members are drawn into the recesses, the members being engaged by the cams during the rotor rotation and moved back into the stator.
