Abstract: A positive-displacement piston mechanism includes a small rotor integrated with a main axis and biased against a cylindrical large rotor for holding a bearing-housing. Slant sliding slots are formed at facing places in equally divided space between the large rotor and the small rotor. Vanes having an angle are fitted into the slots as if they were bridges, and an inlet and an outlet are provided on side-housings.

Abstract: A rotary compressor has a motor-driven rotary body forming a cylindrical chamber in which a roller is rotatable about an axis eccentrically related to the axis of the chamber. The roller is of less diameter than the chamber so that the roller and chamber walls form a space. Vanes are slidably mounted in the body and are spring biased radially against the roller to divide the space into pockets. The volume of each pocket expands and contracts as the body is rotated. A gas inlet and a gas outlet are disposed at an axial end of the chamber. Each pocket communicates with the inlet to draw-in gas during the volume expansion. The drawn-in gas is pressurized during an initial phase of the volume contraction and then discharged through the gas outlet during a subsequent phase of the volume contraction.

Abstract: A rotary compressor includes a stationary member composed of a plate member, and a downwardly projecting shaft defining a first axis. A roller is freely rotatably mounted on the shaft. A cylinder is rotatably mounted below the plate element with the roller disposed therein. The cylinder is rotatably driven about a second axis parallel to and spaced from the first axis. Vanes are mounted in radial slots formed in the cylinder for radial sliding movement relative to the cylinder to divide the cylinder into fluid-compressing and fluid-discharging chambers. The plate element includes an annular groove, and a ring is loosely mounted in the groove for rotation relative to the plate member about the first axis. A radially outer end of each vane includes a protuberance mounted in a respective slot formed in the ring.

Abstract: A rotary engine in which the expansion pressure of a working gas is converted into a mechanical rotary movement consists of an inner engine element with an outer circumferential surface and an outer engine element which surrounds the inner element and has an inner circumferential surface, the two surfaces being disposed closely adjacent and facing each other. Disposed at, for example, the inner surface are three spaced projections, which transmit the expansion pressure of the gas to the inner element, and three expansion chambers between the projections. Four reaction members, which are each movable into the expansion chambers in turn and transmit the gas expansion pressure to the outer element, are mounted at the circumferential surface of the outer element. The two circumferential surfaces have the form of complementary annular surfaces, wherein in cross-section the inner surface has the shape of a concave, parabola-like curve and the outer surface the shape of a convex, parabola-like curve.

Abstract: The internal combustion engine of the invention has a stationary cylindrical casing with inlet and outlet openings for fuel and air supply and for exhausting. Between two cover plates, a ring structure and a rotor enclosed thereby are arranged for rotation about different but parallel and stationary axes. The ring structure comprises a number of arcuate members between which an equal number of swinging fulcrum slides are held. Vanes extending through the fulcrum slides define an inner group of chambers between the ring structure and the rotor to whose periphery the vanes are joined by swivel bearings, and an outer group of chambers between the ring structure and the casing wall. A flow connection is provided from the outer group serving as charging and boosting chambers to the inner group in which compression, ignition and exhaustion take place.

Abstract: The rotary hydraulic servo is integral with a steering shaft and comprises a fluid control valve element rotated by manual steering input, and a multi-lobed rotor mounted in a stator. The stator has a set of reciprocally movable radial vanes cooperating with the arcuately spaced lobes of the rotor to form chambers for pressure fluid for operator selected hydraulic drive of the rotor. The rotor is drivingly connected to a pinion meshing with teeth of the rack for right and left turn power assist steering.
