PURPOSE:To eliminate the possibility of generating seizure between a cam plate and a shoe so as to improve the reliability of a compressor by providing a cam plate supported on a cam plate guide by a bearing means, and a shoe provided on the piston rod of a piston so as to be engaged with the cam plate. CONSTITUTION:When a driving shaft 15 is rotated by a motor, this rotation is transmitted to a cam plate guide 25 through link mechanism formed by the connection of a rotor integrated with the driving shaft 15, an arm 34, a pin 35 and an arm 32, and the cam plate guide 25 also performs the same rotation. Since a cam plate 24 supported on the cam plate guide 25 is supported by a radial bearing 27 in such a way as to be rotatable relatively to the cam plate guide 25, the rotation is not substantially transmitted to the cam plate 24, so that the circumferential sliding motion of the cam plate 24 is not generated between the cam plate 24 and a shoe 23 provided on the piston rod 21 of a piston 20. Accordingly, there is no problem in friction and lubricating difficulty between the cam plate 24 and shoe 23. |
