Abstract:
1. A variable displacement compressor for compressing gas comprising: a housing having a cylinder bore; a drive shaft rotatably supported by the housing; a lug plate connected to the drive shaft so as to rotate together with the drive shaft; a cam plate supported on the drive shaft so as to incline with respect to the drive shaft; a piston accommodated in the cylinder bore for reciprocation, the piston being engaged with the cam plate; and a link mechanism provided between the lug plate and the cam plate for transmitting rotation of the lug plate to the cam plate to reciprocate the piston thereby performing gas compression, an inclination angle of the cam plate being varied while being guided by the link mechanism to change stroke of the piston so that displacement of the compressor is varied, the link mechanism including:
