摘要： A first rotor is rotatably supported by a housing. A second rotor rotates integrally with a rotary shaft. A power transmission mechanism is capable of transmitting power from the first rotor to the second rotor. When supplied with a current, an electromagnetic coil is capable of causing the armature plate to adhere to the first rotor. In a state where the armature plate adheres to the first rotor, the spring clutch couples the second rotor to the first rotor. An urging member is accommodated in the second rotor. The urging member is located between the rotary shaft and the armature plate. Therefore, the power transmission mechanism is compact and achieves a high performance.

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： Refrigerant gas is introduced into a suction chamber through a suction line. Refrigerant gas is allowed to flow from the crank chamber into the suction chamber through an outlet line. An open degree adjustment valve (34) has a first valve body for adjusting an open degree of the suction line and a second valve body for adjusting an open degree of the outlet line. The first valve body and the second valve body are connected to each other. The first valve body moves in such a manner as to increase the open degree of the suction line when the difference between the pressure in the suction chamber and the pressure in the crank chamber decreases, and reduce the open degree of the suction line when the difference between the pressure in the suction chamber and the pressure in the crank chamber increases. Thus, variation of gas pressure is reliably suppressed while maintaining favorable starting performance of the compressor.

摘要： A refrigeration suction mechanism used in a piston type compressor. The compressor comprises a rotary shaft, a plurality of pistons, a compression chamber and a rotary valve. The pistons are arranged in a circumference of the rotary shaft to reciprocate in conjunction with a rotating motion of the rotary shaft through a cam member. An end surface of one of said pistons reciprocates in the compression chamber. The rotary valve includes an introducing passage which allows refrigerant to flow into the compression mechanism through an end opened on an outer surface of the rotary valve. The refrigeration suction mechanism comprises a suction passage and a reactive force transmitting mechanism. The suction passage communicates with the cylinder bore and intermittently communicates with the end of the introducing passage in conjunction with a rotating motion of the rotary valve. The reactive force transmitting mechanism transmits a reactive force applied on one of the pistons that is in a discharging stroke so as to press the rotary valve against a mouth of the suction passage which communicates with a cylinder bore that contains the piston in the discharging stroke.
