摘要： A scroll type fluid machine having two scroll members each having an end plate and a spiral wrap formed on the end plate, the scroll members being coupled to each other such that the wraps thereof mate with each other. One of two scroll members being adapted to make an orbitary movement with respect to the other scroll member while being prevented from rotating around its own axis, so as to form at least one working chamber of different pressures between two scroll members. At least two pressing force imparting chambers are formed on the opposite side of the orbitary scroll member to the wrap. The pressing force imparting chambers includes a first chamber which is communicated through a communication passage with at least one of the working chambers which is not materially communicating with a low pressure port and is not at all communicating with a high pressure port of the machine, and a second chamber which is communicated with the high pressure port through a communication passage, so that fluid pressures of different levels are applied to the first and second pressing force imparting chambers so as to produce a force which presses the orbitary scroll member to the other scroll member.

摘要： A volumetric machine comprises a screw rotatable inside a casing and cooperating with at least one pinion-wheel. The screw has a low pressure end adjacent a low pressure port and a high pressure end adjacent a high pressure port, the high pressure end being provided with an annular sealing device substantially preventing axial leakage towards a cavity maintained at the low pressure to reduce axial thrusts on the screw. The profile of the screw corresponds to that of the casing with a very small clearance, except in an area adjacent the sealing device where the clearance increases from the low pressure side towards the sealing device.

摘要： A device to ensure tightness without friction and thus as reduced as possible clearance at the high pressure end of the screw. At the high pressure side of the screw, the bearing housing of the screw comprises a metal ring which is different from the metal of the screw ring and has a higher coefficient of expansion. This ring fills up a circular recess machined at the end of the screw. This device ensures an almost perfect leak-tightness in the case of compressors, or oil free expansion machines or high pressure pumps.

摘要： The power conversion machine has a piston which is adapted to effect a combined turning and rocking movement internally in a double-curved space. The piston is in drive connection with a rotary shaft via an eccentric disc which is obliquely disposed on the center axis of the rotary shaft. The center axis of the rotary shaft and the center axis of the eccentric disc cross each other in the center of the double-curved space. The double-curved space in defined within a ball shell and is divided into two opposing substantially ball-shaped spaces by means of a stationarily secured circular partition plate. The piston operates simultaneously in the two semi-spherical spaces, the piston passing through the partition plate via a diametrically extending slot. The piston comprises a disc-shaped main portion, and two oppositely directed roller portions which are received in respective semi-spherical spaces. The roller portions are adapted to roll against their respective side of the partition plate, which the main portion is adapted to move with a combined turning and rocking movement in the slot of the partition plate.

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： Internal combustion engine includes a rotary oxidizing gas compressor, a constant volume combustion chamber with pneumatically controlled intake and exhaust valves and a fuel injector, and a rotary combustion gas expander. Each of the rotary compressor and rotary expander has a pair of tangential rotors dependently rotatable in a housing, one rotor having a vane and the other a notch for allowing passage of the vane, to form a fluid tight segmented annular region through which the vane moves. The respective one of the intake valve and the exhaust valve admits a mass of high pressure compressible fluid to the region through a triangular port for expansion or from the region after compression, the mass of fluid being confined in a part of the region between the vane and the surface of the notched rotor and changing in pressure because of the change in arcuate length and volume of the confined part. The respective pairs of rotors are included on the same respective shafts. Two vanes may be included on the one rotor and two notches on the other. Two vaned rotors may cooperate with one notched rotor, the vaned rotors being on separate shafts.

摘要： In an internal gear pump or motor the insert control member between the inner and the outer gear is provided with balancing pockets, which receive fluid under pressure to counter-balance the pressure forces exerted onto the inner and outer gear of the device. Thereby it is obtained, that the radial forces of fluid onto the inner and outer gear are balancing each other by diametrically located oppositional directed fields of force of pressure in fluid. The inner and outer rotors such float freely between radial forces of fluid. Radial rest loads are prevented and the life of the rotors is extended. There may be a single insert or a plurality of inserts and there may be one or a plurality of suction chambers in the device. Additional outer guide means or pressure fields of fluid under pressure may be provided. The loading of the balancing pockets with pressure fluid may be done through respective passages from areas under pressure to said balancing pockets.
