摘要： A vehicle air conditioning apparatus includes a refrigerant circulation circuit. The vehicle air conditioning apparatus has a variable displacement type compressor, a first pressure monitoring point, a second pressure monitoring point and an oil separator in the refrigerant circulation circuit. Also, the vehicle air conditioning apparatus has a control valve in the compressor. The compressor compresses refrigerant gas. Displacement of the compressor is variable. The refrigerant gas includes oil. The second pressure monitoring point is located more downstream than the first pressure monitoring point. The control valve controls the displacement based on differential pressure between the first and second pressure monitoring points. The oil separator is located between the first and second pressure monitoring points in order to separate the oil from the compressed refrigerant gas, thereby the oil separator serves as means for manifesting the differential pressure.

摘要： A displacing device is incorporated in a displacement control valve. The displacing device includes a first pressure chamber, a second pressure chamber, a second bellows, a transmission rod, and an urging spring. The second pressure chamber communicates with a suction chamber. The interior of the second pressure chamber is a suction pressure zone. When the pressure in the suction pressure zone is less than or equal to a predetermined reference pressure, the transmission rod moves an actuation rod (valve body) to open a valve hole. Therefore, a variable displacement compressor is prevented from operating with a large displacement when there is insufficient amount of refrigerant or when the speed of the compressor is high.

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.
