    Abstract: A variable displacement compressor having a rotary shaft and a swash plate is described. The swash plate is mounted on the shaft and rotates integrally with the shaft. The swash plate tilts between a maximum inclined angle and a minimum inclined angle and is connected to a plurality of pistons. The inclined angle of the swash plate is altered by the difference between the pressure in a crank chamber and the pressure in a suction chamber. Each piston reciprocates inside a cylinder bore with a stroke determined by the inclined angle of the swash plate and compresses refrigerant gas, which includes oil mist. A spool is arranged adjacent to the swash plate on the shaft. On the shaft, a thrust bearing is provided between the swash plate and the spool, and a radial bearing is provided in the spool. The spool has an opening opposed to the swash plate. Grooves that allow the flow of refrigerant gas into the spool are formed at the opening in the walls of the spool.

    Abstract: A swash plate of a variable displacement type compressor is swingably provided within a housing. Pistons reciprocate according to the swinging motion of the swash plate. The gas is compressed and discharged in response to the reciprocal motion of the pistons. As a stroke of the piston is varied according to the inclination angle of the swash plate, displacement of the compressor is varied. A displacement detector of the compressor includes a detected piece made of magnet. The detected piece is attached to one of the piston and a member which reciprocates in association with the piston. Detecting wires are arranged along the reciprocating locus of detected piece, and include a plurality of cyclic units which cross the center line extending in the longitudinal direction.

    Abstract: A driving rotary shaft is rotatably carried on a compressor body of a variable displacement compressor. On axial one side of a sleeve slidably carried on the driving rotary shaft, there is disposed a first spring of a displacement setting device for biasing the sleeve in one axial direction and holding a stopper, with which the sleeve is engageable, at a stop position on the driving rotary shaft. On the axial other side of the sleeve, there is disposed a second spring of the displacement setting device for biasing the sleeve in the other axial direction, the second spring being weaker than the first spring. At the starting of the compressor, the first spring holds the stopper at the stop position against a repulsive force of the second spring to hold the sleeve engaged with the stopper at a fixed position. This makes it possible to set the strengths of individual members and the capacity of a clutch to be smaller than those in the prior art, leading to reductions in size, weight and cost of the entire compressor.

    Abstract: A multi-cylinder piston-operated compressor having a combined cylinder block closed on both axial ends by front and rear housing and provided therein with a reciprocative piston mechanism, for sucking, compressing, and discharging a refrigerant gas, and a connecting flange, from which the refrigerant gas after compression is sent toward a cooling circuit. The connecting flange defines a muffling chamber in cooperation with a circumferential section of the combined cylinder block for suppressing the pulsation in discharge pressure of the refrigerant gas. The compressor further has a gas expansion chamber in which an expansion and a partial collision of the compressed refrigerant gas spouted from orifices take plate to weaken the pulsation in the discharge pressure of the gas with the least discharge loss.

    Abstract: A refrigerant compressor including a compressor housing having a cylinder block is disclosed. A plurality of cylinders are formed around the periphery of the cylinder block. A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism. A crank chamber is formed between the cylinder block and a front end plate of the compressor housing. The drive mechanism includes a drive shaft, a rotor disposed on the drive shaft, a slant plate with an adjustable slant angle disposed adjacent the rotor and a wobble plate disposed adjacent the slant plate. The drive shaft is rotatably supported within the front end plate. Rotation of the drive shaft causes rotation of the rotor and the slant plate, causing nutational motion of the wobble plate to reciprocate the pistons within their cylinders. The compressor housing includes a rear end plate defining suction and discharge. A communicating path communicates between the crank chamber and the suction chamber. A stroke of pistons is changed by adjusting a slant angle of the slant plate. An elastic member urges the slant plate toward minimum slant angle to adjust the slant angle of the slant plate.

    Abstract: A refrigerant compressor having pistons reciprocated in respective cylinders by a wobble plate driven by an input rotor which is secured on a drive shaft, in which improved refrigerant gas flow within the housing is achieved. A balance hole is provided for returning the blow-by gas, which is leaked from the cylinders through the gaps between the cylinders and pistons to the crank chamber, to the compressor suction chamber from the crank chamber. The balance hole comprises a first fluid passageway formed in a front end plate and a second fluid passageway connected between the first fluid passageway and the suction chamber. One end of the first fluid passageway opens into a hollow portion formed on a axial end surface of the input rotor. The rotor is formed with at least one opening at its outer peripheral surface which communicates between the crank chamber and the hollow portion. Therefore, the amount of lubricating oil which is discharged together with the returned blow-by gas through the balance hole is reduced.

    Abstract: A compact lightweight multicylinder swash plate compressor is disclosed having a metallic double-ended piston with piston heads reciprocated in aligned metallic cylinder bores. Each piston head has a diametrical dimension substantially less than the diametrical dimension of its respective bore to provide a substantial annular space therebetween and a solid seal-support ring of slippery material is expanded over each piston head and contracts into a circumferential groove therein. Each ring is sufficiently thick that the memory recovery thereof after further contraction forced by a tool causes the ring to sealingly engage its respective bore immediately after assembly with its piston head therein. The metal of the piston head on opposite sides of the groove is thereby prevented from touching the metal of its respective bore throughout its reciprocation in the bore. Each ring groove is formed with a plurality of projections which are spaced about and project outward from the bottom thereof. The projections project sufficiently outward and are configured so that they substantially bite or imbed themselves in the underside of the ring mounted thereover during assembly of the piston heads with the rings thereon in their respective bores. Each piston is thereby positively prevented from both rotary and longitudinal rubbing movement in its rings to thereby prevent the rings from wearing away the metal of the piston heads at the bottom and shoulders of their groove whereby both sealing and prevention of metal to metal contact between the piston heads and their respective bores is maintained by the rings.
