摘要： A compressor having a crank chamber in which a large amount of lubricating oil is constantly maintained. The compressor includes a pressurizing passage through which refrigerant gas flows from a discharge chamber to the crank chamber. A displacement control valve varies the displacement of the compressor by adjusting the flow in the pressurizing passage thereby changing the pressure in the crank chamber and altering the inclination of a swash plate. The compressor further includes a bleeding passage. An oil separator is arranged in the bleeding passage to separate lubricating oil from the refrigerant gas flowing through the bleeding passage. The oil separator and the crank chamber are connected to each other by a recovery passage, through which the separated lubricating oil is returned to the crank chamber, and a pressurizing passage. A venturi tube is employed to help transfer oil from the oil separator to the crank chamber.

摘要： A displacement control valve included in a variable displacement compressor. The compressor includes a fluid passage for connecting a crank chamber to a discharge chamber. The control valve includes a valve chamber connected to the crank chamber through the fluid passage, a valve hole connected to the discharge chamber through the fluid passage, and a valve body located in the valve chamber. A bellows influences the valve body through a pressure sensitive rod in accordance with suction pressure. A solenoid includes a fixed iron core and a plunger arranged in a plunger chamber. The plunger urges the valve body through a solenoid rod by a force determined by the level of electric current supplied to the solenoid. The fixed iron core, which is located between the valve chamber and the plunger chamber, includes a guide hole for receiving the solenoid rod. An annular passage for connecting the valve chamber to the plunger chamber is formed between the guide hole and the solenoid rod. Accordingly, the pressure of the crank chamber is applied to the plunger chamber through the valve chamber and the annular passage. In this control valve, the valve body has desirable operating characteristics without relying on parts having precise dimensions.

摘要： A compressor has a front housing, cylinder block and a rear housing. The housings and cylinder block are secured to one another by a plurality of bolts. A plurality of pistons reciprocally move in cylinder bores to compress gas. Each of said bolts has a shaft extending through the housings and the cylinder block. A cam plate is supported on a drive shaft for integral rotation therewith to convert the rotation of the drive shaft to reciprocal movement of a piston in the cylinder bore. The piston rotates about its axis in accordance with rotation force transmitted from the cam plate and abuts against the shaft of the bolt, which extends in close proximity to the piston. The rotating piston abuts against the shaft so that the rotation thereof is restricted. The shaft has a diameter greater than that of a threaded portion formed at an end of the bolt. Since the threaded portion is smaller, the threaded portion does no damage to the piston during assembly.

摘要： An axial multi-piston compressor includes a drive shaft, a cylinder block having cylinder bores formed therein and surrounding the drive shaft, and a plurality of pistons slidably received in the respective cylinder bores, wherein the pistons are successively reciprocated in the cylinder bores by a rotation of the drive shaft so that a suction stroke and a discharge stroke are alternately executed in each of the cylinder bores. During the suction stroke, a fluid is introduced into the cylinder bore, and during the compression stroke, the introduced fluid is compressed and discharged from the cylinder bore such that a residual part of the compressed fluid is inevitably left in the cylinder bore when the compression stroke is finished. The compressor further includes a rotary valve for allowing the residual part of the compressed fluid to escape from the cylinder bore into another cylinder bore governed by the compression stroke.
