Abstract:
A variable displacement compressor, in which displacement is varied by changing the strokes of a plurality of reciprocating pistons by changing the inclination of an inclining drive member relative to the axis of a shaft the compressor comprising:a housing for accommodating the shaft and the inclining drive member, wherein the housing includes a first housing member having a bearing for supporting the shaft such that the shaft is supported within the housing by only the bearing on the first housing member, and a second housing member having a plurality of cylinder bores for accommodating the pistons; and an arm for transmitting torque from the shaft to the inclining drive member, such that the inclining drive member oscillates when driven, wherein a coupling between the arm and the inclining drive member includes a linking groove, which is provided on one of the arm and the inclining drive member, and a link pin, which is attached to the other of the arm and the inclining drive member, wherein the link pin is fitted in and slides within the linking groove such that the inclining drive member can move radially with respect to the axis, and the linking groove is open at one end to receive the linking pin.
