Claims

[Scope of utility model registration request]

a casing having a crank chamber; a cylinder head that closes one open end of the casing; a main shaft rotatably disposed within the casing;
a swash plate that is located in the crank chamber and has a boss portion that is tiltably provided on the main shaft and that surrounds the main shaft; and a swash plate that is provided on the boss portion of the swash plate and that swings in response to rotation of the swash plate. a plate, a balance ring attached to the tip of the boss portion and in sliding contact with the rocking plate, a plurality of cylinders provided in the casing on the radially outer side of the main shaft, and a balance ring capable of reciprocating movement within the cylinders. In a variable capacity swash plate compressor including an inserted piston and a conrod connected at one end to the piston and at the other end to the rocking plate, the connecting rod expands toward the rocking plate. A tapered recess is provided in the balance ring, and a through hole is provided in the balance ring that communicates a portion of the balance ring that slides with the rocking plate and an outermost peripheral portion of the recess, one end of which connects to the through hole. The rocking plate is provided with a first communication hole which faces each other and whose other end opens at the ball connection part with the conn rod, and a second communication hole which communicates the ball connection part with the crank chamber. Variable capacity swash plate compressor.
