    摘要： An external combustion engine is disclosed of the type including two or more circular rotors rotatably supported, one of the rotors acting as a power rotor and rotating in tangential contact with the other sealing rotor. The power rotor is formed with a radially projecting piston passing into a mating recess with the sealing rotor at a corresponding circumferential location. Steam or other working fluid is admitted via an intake port located opposite one face of the power rotor to cause rotation of the power rotor by expansion of the fluid in a working chamber defined by the space behind the piston. As the power rotor continues to rotate, the working chamber passes into communication with an exhaust port preparator to another power stroke. A vacuum relief port is provided at an intermediate location which relieves any vacuum condition which develops behind the piston during part throttle operating conditions of the engine. A pressure balancing groove is located on a face of the power rotor and pressurized with working fluid to balance the pressure acting on the power rotor by the location of the intake port on the opposite face of the power rotor. An absorber chamber is provided downstream of the throttle valve and upstream of the intake port to smooth out the pressure forces created by intermittent flow of fluid through the intake port. An elliptical port throttle valve design is disclosed which minimizes the wire drawing effect of the working fluid acting on the valve member during operation of the valve. A special rotor sealing surface treatment is disclosed comprising a series of slight depressions or holes formed in the mating faces of the power rotor and which generate a sealing due to condensation of the escaping steam in the surface indentations. Two and three rotor versions of the engine are described as well as one, two, and four power stroke per revolution embodiments.

    摘要： A rotary device for use as a pump or motor including vane structure pivoted to a rotor and a speed ring for reducing friction between a motor housing and the rotor vane structure. The speed ring is positioned between the motor housing and rotor and bearings are provided in the speed ring to permit free rotation of a portion of the speed ring within the housing. The rotor vanes are provided in pairs at the radially outer portions of alternate radially inner and outer rotor portions for pivotal movement toward and away from the speed ring on rotation of the rotor which is displaced axially from the axis of the housing and speed ring which are concentric. Connecting pressure-equalizing grooves are provided in the rotor and side covers of the motor structure operable to equalize the pressure between radially outer and radially inner portions of the rotor separated by vanes over a portion of the angular rotation of the rotor.

    摘要： A casing (31) houses therein an expansion mechanism (60) and a compression mechanism (50). The expansion mechanism (60) has a rear head (62) in which a pressure snubbing chamber (71) is provided. The pressure snubbing chamber (71) is divided by a piston (77) into an inflow/outflow chamber (72) which fluidly communicates with an inflow port (34) and a back pressure chamber (73) which fluidly communicates with the inside of the casing (31). The piston (77) is displaced in response to suction pressure variation whereby the volume of the inflow/outflow chamber (72) varies. This enables the inflow/outflow chamber (72) to directly perform supply of refrigerant to or suction of refrigerant from the inflow port (34) which is a source of pressure variation, thereby making it possible to effectively inhibit suction pressure variation.
