<p>PURPOSE:To provide an excellent balance by means of a low-cost means by a method wherein a balance weight is situated on a surface positioned facing the cylinder block of a rocking plate rotatably set on the slope of a swash plate, and a slip contact part to regulate axial movement of the rocking plate is mounted to a part of the balance weight. CONSTITUTION:By rotating a drive shaft 6 through an electromagnetic clutch 26 by means of a drive force from an external drive source, a swash plate 8 is rotated through a rotor 7, and a rocking plate 9 rotation of which is blocked by a guide 12 is rocked along with rotation of the swash plate 8. This rocking causes reciprocating movement within a cylinder 2 of a piston 14 through a piston rod 13, and compresses gas sucked in the cylinder 2 through a suction hole 21 from a suction chamber, and delivers the gas through a delivery chamber 18 and a delivery port 20. In this case, a balance weight 32 is mounted on a surface positioned facing a cylinder block 3 of the rocking plate 9 in a state to be coupled to the swash plate 8. A slip contact part to regulate axial movement of the rocking plate 9 is mounted to a part of the balance weight 32.</p> |
