摘要： A control valve used in a variable displacement compressor includes a valve chamber (46), a valve body (43) and a pressure sensing chamber (48). A pressure sensing ball is movably located in the pressure sensing chamber (48) and divides the pressure sensing chamber (48) into a first pressure chamber (55) and a second pressure chamber (56). First and second pressure monitoring points (P1, P2) are located in a refrigerant circuit. The first pressure chamber (55) is exposed to the pressure at the first pressure monitoring point (P1). The second pressure chamber (56) is exposed to the pressure at the second pressure monitoring point (P2). The ball is displaced based on the pressure difference between the first pressure chamber (55) and the second pressure chamber (56). The position of the valve body (43) is determined based on the position of the pressure sensing member (54).

摘要： According to the structure for damping the pulsations of discharge pressure of a compressor of the present invention, in the annular discharge chamber 28 divided on the outer circumferential side in the rear housing 5, two bulkhead sections 35 are extended from positions on both sides of the outlet 23 in the circumferential direction in such a manner that they are separate from each other. The end portion of each bulkhead section 35 is extended to halfway between the first discharge port section 20 and the second discharge port section 21. The flow path from the first discharge port section 20 to the outlet 23 is directed to the opposite side to the outlet 23 and then turned back to the outlet 23. Therefore, the length of the flow path from the first discharge port section 20 to the outlet 23 becomes relatively long.

摘要： A torque limiting mechanism for transmitting power from an external drive source (Eg) to the drive shat (17) of a compressor (C). A pulley (33), which is coupled to the external drive source, has elastic members (44). A hub, which is attached to the drive shaft, has engaging portions (41). A coupler member (59) is located between the pulley (33) and the hub (38). The coupler member is engaged with the elastic members (44) and with the engaging portions (41) such that power is transmitted from the pulley to the hub. The urging members urge the coupler member (59) such that the coupler member is disengaged from the engaging portions (41). When power is transmitted from the pulley to the hub, the elastic members (44) maintain the coupler member (59) engaged with the elastic members (44) and with the engaging portions (41). When load generated due to power transmission exceeds a predetermined level, the elastic members (44) are deformed such that the coupler member (59) is disengaged from the elastic members (44). When disengaged from the elastic members (44), the coupler member is disengaged from the engaging portions (44).

摘要： An improved control apparatus for controlling the displacement of a variable displacement compressor. A control valve 46 includes an operating rod 53, which is urged by a force based on a differential pressure PdH-PdL between two pressure monitoring points P1, P2, which are located in a refrigeration circuit. The control valve causes the compressor to seek a target displacement. A computer limits the target displacement when the demand for cooling is decreasing to improve fuel economy and to extend the life of the compressor.

摘要： A control valve (200) controls the pressure in a crank chamber (5) of a compressor to change the displacement of the compressor. The compressor includes a discharge chamber (22), a suction chamber (21) and a supply passage (28), which connects the discharge chamber (22) to the crank chamber (5). The control valve (200) regulates the supply passage (28). The control valve (200) includes a valve body (43), a spool (54) and a solenoid (100). The valve body (43) adjusts the size of an opening in the supply passage (28). The spool (54) moves the valve body (43) in accordance with the difference (Pd-Ps) between the pressure in the discharge chamber (22) and the pressure in the suction chamber (21). The solenoid (100) urges the valve body (43) by a force, the magnitude of which corresponds to a supply of electricity. The urging force of the solenoid (100) represents a target value (TPD) of the pressure difference (Pd-Ps). The spool (54) moves the valve body (43) such that the pressure difference (Pd-Ps) seeks the target value (TPD). The control valve (200), which is located in the compressor, permits the compressor displacement to be accurately controlled regardless of a thermal load on a evaporator (33).

摘要： A compressor having a device for recovering lubricating oil. The compressor includes a discharge chamber (28) and a muffler (43), which attenuates the pressure pulsation of refrigerant gas sent out from the discharge chamber (28). The muffler (43) is defined by a muffler base (41), which is formed on the cylinder block (12), and a muffler cover (42), which is attached to the muffler base (41). The muffler (43) includes a first muffler chamber (43A) and a second muffler chamber (43B), which are connected by an opening (46). The muffler cover (42) has a gas outlet (48) for sending the refrigerant gas out of the compressor from the second muffler chamber (43B). Lubricating oil separated from the refrigerant gas in the first muffler chamber (43A) is sent to the crank chamber (15) through a recovery passage (52). The location of the gas outlet (48) can be easily changed by replacing the muffler cover (42). Thus, the compressor can be easily adapted to different engine compartments.

摘要： A single headed piston type refrigerant compressor having a cylinder block forming therein a plurality of cylinder bores receiving a plurality of single-headed pistons for reciprocation therein, and a front housing joined to the cylinder block to define a crank chamber for receiving therein a cam plate. An extended bore-forming portion of the cylinder block having partial cylindrical guide surfaces each being continuous with the corresponding cylinder bore and capable of being in slide contact with the piston head portion of the single-headed piston and the outer circumference of a shoe-holding portion of the single-headed piston is formed by extending a peripheral portion of a front end of the cylinder block into the crank chamber. A projecting portion formed on each single head piston protrudes from a side end surface of the shoe-holding portion extending behind the piston head portion into the crank chamber. Therefore, the extended bore-forming portion can additionally be extended toward the crank chamber by a length corresponding to the distance of dislocation of the projecting portion into a space on the front side of the crank chamber to increase
additionally the length of contact of the piston with cylinder bore.
