摘要 |
A variable-capacity swash-plate operated single-headed piston type compressor including a crank chamber having a capacity large enough for receiving a drive shaft, a rotor, a swash plate and shoes engaging between the swash plate and single headed pistons and provided with an open mouth for directly receiving a refrigerant gas returning from an external refrigerating system, a suction passageway for providing a fluid communication between the crank chamber and a suction chamber from which the refrigerant gas is sucked into respective cylinder bores so as to be compressed by the single headed pistons, and a capacity control valve provided with a bellows element for adjustably changing the cross sectional area of the suction passageway in response to a change in a pressure prevailing in the suction passageway.
