Abstract: A hydraulic machine-has a rotating group located within a housing and a port plate to control flow from the barrel of the rotating group to inlet and outlet ports. The port plate is sealed against one of the housing or barrel and sleeves extend between the other of the housing or barrel to accommodate misalignment between the barrel and housing as the barrel rotates.

Abstract: In a swash plate type compressor having a swash plate rotated by a drive shaft, the swash plate is made by attaching a bronze-based metal plate to a base plate. The bronze-based metal plate forms an axial end of the swash plate, along which a shoe slides when the drive shaft is driven is rotated. The shoe is held by a piston slidably inserted in a cylinder bore which is formed in a cylinder block. It is preferable that the base plate is made of iron.

Abstract: A porous bronze 1b and a resin 1c impregnated in pores of the porous bronze 1b formed on a backing metal 1a constitute a bearing 1. At a surface to be brought into contact with a crank shaft 5, porous bronze 1b and resin 1c are sparsely exposed. Ratio of area of exposure of porous bronze 1b at the contact surface 1d is at least 5% and at most 60%. Thus a bearing for a refrigerating compressor having high seizure resistance at the time of boundary lubrication and having small amount of wear caused by sliding as well as a refrigerating compressor employing the same can be obtained.

Abstract: A compressor assembly is disclosed including a compressor mechanism resiliently mounted within a hermetically sealed housing. The compressor mechanism includes a crankcase having a radially extending mounting flange portion, which is resiliently connected to the housing sidewall at a plurality of circumferentially spaced locations by a plurality of mounting assemblies. Each mounting assembly comprises a rubber bushing received within a hole in the mounting flange, and a threaded stud that extends through a hole in the bushing and engages a threaded hole in a steel block welded to the housing sidewall above the mounting flange. A washer and retaining nut on the bottom of the threaded stud suspendingly support the mounting flange. In this manner, only a peripheral portion of the washer contacts the mounting flange circumjacent the hole therein, thereby minimizing noise transmission to the housing. Lateral movement of the compressor mechanism is absorbed by the bushing.

Abstract: A hermetic compressor assembly is disclosed including a compressor mechanism and an electric drive motor within a hermetically sealed housing. The electric motor includes a rotatable rotor and a stator. In one disclosed embodiment, the stator is friction fit within the housing and a rotor is press fit over a crankshaft journalled in a crankcase of the compressor mechanism. The crankcase is selectively positioned within the housing and mounted thereto by means of mounting pins. In another disclosed embodiment, the motor is mounted to the compressor mechanism and the compressor crankcase is axially supported in the housing. A mounting pin is used to prevent rotation of the compressor mechanism within the housing caused by torque forces produced by dynamic operation of the motor. The disclosed mounting pins are received within holes in the crankcase and extend radially outwardly through oversized apertures in the housing. The pins are selectively positioned in the apertures prior to welding. A method of assembling a compressor having mounting pins is also disclosed.

Abstract: A cylinder block for a multi-cylinder hydraulic or hydrostatic piston device is provided having a control layer comprising a sintered friction metal layer sintered onto the cylinder block under the simultaneous action of pressure and heat. The end surface of the cylinder block is first provided with an electrodeposited metal layer. The electrodeposited layer has a crystal lattice constant compatible with the sintered layer and the material of the cylinder block. The cylinder block is preferably made from steel or aluminum and the electrodeposited layer is preferably copper or nickel. After the friction metal layer, preferably bronze, is sintered onto the electrodeposited layer, the cylinder block is treated to improve the strength and wear characteristics of the cylinder block without injuring the sliding friction characteristics of the sintered friction metal layer. In the case of steel, the preferred treating process is gas nitriding, and in the case of aluminum or an aluminum alloy, the preferred treating process is anodizing.

Abstract: A pump comprising a supporting structure including a bearing support, a wobble plate, a bearing between the bearing support and the wobble plate for permitting the wobble plate to nutate and for transmitting radial loads from the wobble plate to the bearing support, a cam rotatably mounted on the supporting structure for causing the wobble plate to nutate, and a mechanism for drivingly coupling the cam to a shaft of a motor. Radial loads are transmitted by the bearing to the supporting structure rather than to the cam. The wobble plate is coupled to a suitable output device such as the diaphragm of a diaphragm pump.

Abstract: A heat pump unit comprising a compressor and an expansion machine for respectively compressing and re-expanding a medium which circulates in a heating or cooling circuit. The power used for compressing this medium is at least partly recovered in the expansion machine and is used for driving the compressor. The compressor and the expansion machine are inner axle, intermeshing rotary piston engines which are arranged directly adjacent to one another on a common shaft. The inner side walls of the rotary engines are adjacent to each other and have cavities and thermal insulating means interposed between them and, while being interconnected, are fixedly connected on the one hand to the shaft and on the other hand with outer rotors. The shaft is rotatably journalled in eccentrics of inner rotors, which eccentrics are rigidly connected with a stationary housing.
