Abstract: A shaft sealing assembly is located in a suction chamber of a swash plate type compressor to seal the space between a drive shaft and a housing. A first end portion of the drive shaft is supported by a first radial bearing. A second end portion of the drive shaft is supported by a second radial bearing. The suction chamber is closer to the first end portion of the drive shaft than the first radial bearing is. An axial passage is formed in the drive shaft to connect the suction chamber to the crank chamber. An inlet of the axial passage is closer to the second end portion than the second radial bearing is. An outlet of the axial passage is closer to the second end portion than the first radial bearing is.

Abstract: A compressor has an odd number of aligned pairs of cylinder bores. A double-headed piston is accommodated in each aligned pair of bores. The time at which gas is discharged from each cylinder bore is different from that of all of the other cylinder bores. The compressor has a pair of reducing devices, one reducing the pulsation amplitude of the gas discharged from the front cylinder bores and the other reducing the pulsation amplitude of the gas discharged from the rear cylinder bores. The reducing devices reduce the gas pulsation amplitudes of the front and rear cylinder bores at a substantially equal rate. Each reducing device includes a discharge chamber for receiving the gas discharged from the associated cylinder bores and a discharge passage connected to the discharge chamber. The discharge chambers of the reducing devices have equal volumes, and the discharge passages of the reducing devices have equal lengths and equal cross-sectional areas. This structure improves the vibration characteristics of the compressor and thus reduces noise.

Abstract: A swash plate tiltably supported on a drive shaft is controlled by adjusting the pressure in a crank chamber. When an electromagnetic valve is de-excited, the high-pressure refrigerant gas in a discharge chamber is supplied to the crank chamber so that the inclination angle of the swash plate is shifted to its minimum inclination from its maximum inclination. An open/close mechanism located in a suction passage gradually opens or closes the suction passage in accordance with the differential pressure between the pressure in the external refrigeration circuit located upstream the open/close mechanism and the pressure in a suction chamber. When the inclination angle of the swash plate is minimized, the open/close mechanism closes the suction passage. It is therefore possible to prevent frosting while also suppressing rapid changes in load torque.

Abstract: A cam plate is mounted on a drive shaft in a crank chamber. A plurality of pistons are operably coupled to the cam plate. The rotation of the drive shaft is converted to a linear reciprocal movement to compress and discharge refrigerant gas containing oil mist. An extracting passage extracts the refrigerant gas from the crank chamber to remove an excessive pressure in the crank chamber. The extracting passage is open to an accommodating chamber which receives the refrigerant gas from the passage. A bearing is disposed in the accommodating chamber and receives an axial load acting on the drive shaft. A bolt absorbs an assembly tolerance of the bearing. A first protuberance is provided on the bearing protruding in a radial direction with respect to the drive shaft so as to become aligned with the passage. The first protuberance engages an inner surface of the accommodating chamber to prevent rotation of the bearing.

Abstract: An oil diverting unit, incorporated in a compressor housing of a refrigerant compressor for a climate control system of an automobile, cooperating with a shaft seal unit mounted on a drive shaft of the compressor, so as to divert a flow of the lubricating oil which was suspended in the refrigerant gas and has leaked out of the interior of the compressor housing, to thereby prevent the lubricating oil from reaching a solenoid clutch mounted on a front portion of the drive shaft of the compressor. The oil diverting unit has an oil blocking plate member made of elastic material so that the plate member is elastically press-fitted in the compressor housing so as to define an oil dam for holding the lubricating oil and permitting the oil to be drained from the dam through a drain passageway toward the exterior of the compressor housing.

Abstract: An air conditioning refrigerant compressor assembly includes a swash plate disposed on a drive shaft centrally within a housing. Three double-ended pistons are reciprocally supported on the swash plate within respective front and rear compression chambers. A pulley is freely rotatably supported concentrically about the drive shaft and connected by a flexible endless driving belt to a power take-off of an engine. A hub is fixedly retained on the end of a drive shaft. An annular torque cushion made of an elastomeric material is bonded to the hub and extends radially outwardly therefrom to support an outer ring concentrically about the drive shaft. An armature plate is fastened to the outer ring. An electromagnetic solenoid creates a field of magnetic flux when energized which draws the armature plate into frictional engagement with the pulley causing the rotary motion of the pulley to be transferred to the drive shaft which rotates the swash plate within the housing. The torque cushion has a tapering axial thickness decreasing steadily from a maximum thickness adjacent the hub to a minimum thickness adjacent the outer ring.

Abstract: A slant plate type compressor including a compressor housing having a cylinder block is disclosed. A plurality of cylinders are formed around the periphery of the cylinder block and 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 rotatably supported in the compressor housing, a rotor coupled to the drive shaft and rotatable therewith, and a coupling mechanism for drivingly coupling the rotor to the pistons such that they rotary motion of the rotor is converted into reciprocating motion of the pistons. The coupling mechanism includes a plate having a surface disposed at a slant angle relative to the drive shaft. The slant angle changes in response to a change in pressure in the crank chamber to change the capacity of the compressor. The compressor housing includes a rear end plate including suction and discharge chambers. A communication path communicates the crank chamber and the suction chamber. A valve control mechanism controls the opening and closing of the communication path to cause a change in pressure in the crank chamber. A flow control mechanism formed in the cylinder block admits reduced discharge gas pressure to the crank chamber from the discharge chamber to control the crank chamber pressure which controls the slant angle of the slant plate.

Abstract: A multi-cylinder piston-operated compressor having a cylinder consisting of an axially combined cylinder block closed at both axial ends by front and rear housings having suction and discharge chambers therein, a reciprocative piston mechanism arranged in the cylinder for sucking, compressing, and discharging a refrigerant gas, and a connecting flange from which the refrigerant gas after compression is sent toward an air-conditioning circuit. The cylinder block and the connecting flange define a muffling chamber for deadening pulsation in the pressure of the discharged refrigerant gas. The compressor further has front and rear delivery passageways axially extending from the front and rear discharge chambers and having different axial lengths, to cause a pressure differential between the flow of the discharged refrigerant gas passing through the front delivery passageway and that of the discharged refrigerant gas passing through the rear delivery passageway, thereby producing an agitated flow of the compressed refrigerant gas within the muffling chamber.
