Abstract: A combustion apparatus having a housing including an inner surface that defines at least one chamber, a rotor, a rotor shaft, an intake shaft, an exhaust shaft, and a gearing mechanism. The chamber includes an intake valve port and an exhaust valve port, and the rotor shaft is coupled to a gear at one end and has at least two opposing flat surfaces received by an opening in the rotor. The intake and exhaust shafts are geared to the rotor shaft and have at least one opening each that is aligned with the intake and the exhaust valve ports. A gearing mechanism selectively controls the duration in which the openings are aligned with the ports. Two or more rotors may be utilized to produce more power and reduce vibration.

Abstract: At the time of charging a power storage device from a commercial power supply, electric power from the commercial power supply is applied to a neutral point of each of first and second motor generators. A rotation preventing control unit (222) determines one phase to be subjected to switching control in the first inverter, based on a rotation angle (?1) of the first motor generator. Further, rotation preventing control unit (222) calculates torque generated in the first motor generator, generates a torque control value for canceling out the torque, and outputs the value to a phase voltage operating unit (214) for motor control.

Abstract: The invention relates to a rotary piston engine, in particular a rotary engine of trochoidal design, with a side disk (4) on the exhaust side and a rotary piston (6) with at least of one, and preferably three, through-flow openings (6) through which the mixture can flow axially, wherein the side disk (4) on the exhaust side has a side exhaust port (43) and the at least of one through-flow opening (60) has an asymmetric internal contour (600) at least on its exhaust side, so that when the rotary piston (6) passes over the side exhaust port (43) the said side exhaust port (43) is not in fluid communication with an internal area of the through-flow opening (60). The invention further relates to a rotary piston (6) for a rotary piston engine.

Abstract: The problems of prior compressor structures relying upon conventional check valves are obviated by using, instead, flow control passages which operate to control flow while avoiding mechanical moving elements which may become problematical.

First and second piston assemblies (30 and 32), each of which includes at least one pair of diametrically opposed pistons (30A and 30B, and 32A and 32B), are located in the working chamber. Piston assemblies (30 and 32) are connected to the engine output shaft through a differential (78) and the Sakita gear sets (74 and 76), each of which gear sets includes a Sakita type 1 gear (74A or 76A) and a Sakita type 2 gear (74B or 76B). The piston assemblies rotate at variable speed, whereby pistons of the slower speed are trailing pistons during portions of the power and intake phases of engine operation. In one embodiment, the Sakita type 1 gear includes teeth in the form of rollers. Also, spark plugs embedded within piston assemblies (30 and 32) are accessible from outside.

Slots are made in the peripheral portion of the rotor 5, and movable blades 8, which during rotation of the rotor 5 move along the wave-like channel 10, are mounted in the slots. The blades 8 have a form of flattened cylinders with tangential grooves 16 positioned diametrically opposite each other, and disk end portions positioned at both sides of the grooves 16. There are sealing elements 17, mounted with the possibility for movement along the perimeter of disk portions, in the grooves on the circumference of the disk portions. The slots of the rotor 5 have a form corresponding to a cross section of the blade 8 in a diametral plane perpendicular to the direction of the tangential grooves 16.

Abstract: An engine with a single correct direction of rotation and one or more pairs of two-sided rotary pistons (22A and 22B, 38A and 38B, 46A and 46B) with the two pistons of one pair having continuous, overlapping torque production for self-starting operation. Each pair of multiple pairs of pistons and their housings (24A and 24B, 40A and 40B, 48A and 48B) have identical cross sections and graduated thickness relative to the other pairs to sustain multiple expansion. Two sets of inlet valves for fuel, oxidizer and liquid (58A, 60A, 62A and 58B, 60B, 62B) feed two aphodid type combustion chambers (54A and 54B) at the inlet ports (26A and 26B) in the smallest volume pair of housings (24A and 24B).

Abstract: A planetary system, mounted within a housing, is the basis of manufacturing a motor, a pump, or a fluid flow meter. The housing is provided with an inlet and an outlet. The planetary system comprises: a cylindrical core (1) and its axis (2), two discs (9) mounted on the two bases of the core, the planets (4) rotated into special circular recesses of the core, and the transmission system (gears 11-14) giving motion to the planets. When a motor is used to rotate the shaft (2), the planetary system is converted into a pump since it sucks (depending on the supply) air or liquid from the inlet and discharges the same under pressure at the outlet. When on the other hand the inlet of the planetary system is connected to a duct containing a fluid under pressure, the planetic system is converted into a flow meter or a hydraulic motor or a gas motor, for liquids or gases respectively. If as depicted in FIG.

A plurality of radially disposed vanes are mounted in the rotor for radial reciprocating movement relative to the axis of rotation of the rotor. Novel interconnecting cam means are provided between the outer shell of the housing and the vanes to initially actuate the vanes radially outwardly upon rotation of the rotor to positively position and maintain the outer ends of the vanes in close operative proximity to the inner peripheral surface of the irregularly shaped cavity.
