摘要： PROBLEM TO BE SOLVED: To solve problems of a conventional variable displacement swash plate compressor, wherein for example, when a piston reciprocates in a cylinder bore, the piston finely rotates around the cylinder bore axis and makes noise by contacting with the cylinder block and a contact part wears. SOLUTION: In the piston structure of the swash plate compressor, the piston 10 is provided with a fine rotation restricting part for an inner wall of a cylinder block 20 in this compressor. In the fine rotation restricting part, a non-contact part which does not contact with the inner wall of the cylinder block and end parts which contact with the inner wall of the cylinder block at both sides across the non-contact part are formed so that one of the end parts contacts with the inner wall of the cylinder block at two points when the piston finely rotates and one of its end parts contacts with the inner wall of the cylinder block and another one is apart from the inner wall. Thus, a space is formed between one of the end parts and the inner wall of the cylinder block. COPYRIGHT: (C)2009,JPO&INPIT

SOLUTION: A cam mechanism 32 attached to the rear end of a spindle 12 inside a cam chest 30 is adapted to rotate on the spindle 12 as the center axis or rotation axis according to the rotation thereof. The mechanism 32 is formed in its outer periphery with can grooves 32a. Suction valve elements 36 arranged to open or close suction ports 19a are formed with suction ports 36a and are adapted to rotate on their center axis extending perpendicularly to the axis of the spindle 12. The valve elements 36 are also provided with offset driving pins 36b, which are slidably fitted into the grooves 32a in the mechanism 32. The mechanism 32 thus rotatively reciprocates the valve elements 36 about their center axes.
