Claims (1)

[Scope of utility model registration request] The rotation of the swash plate on the rotating shaft supported by the cylinder block is converted into the reciprocating motion of the double-ended piston in the cylinder bore, and the cylinder block is connected to both the front and rear housings, which are joined to the end face of the cylinder block via a seal ring. The suction chamber and the discharge chamber are divided by a partition wall, and the suction chamber surrounds the discharge chamber, and the refrigerant gas is introduced from the suction chamber to the compression chamber by the double-headed piston's double-headed piston. In a swash plate compressor that discharges refrigerant gas from a compression chamber to a discharge chamber by the forward movement of a piston, a discharge passage connecting the discharge chamber and an external refrigerant gas circuit is provided on the outer circumferential side of the cylinder block in the direction of the rotation axis. The partition wall is interposed between the entrance of the discharge passage in the discharge chamber and the seal ring, and the discharge chambers on the left and right of the entrance of the discharge passage are interposed between the partition wall near the entrance of the discharge passage and the seal ring. Seal structure in a swash plate compressor with cooling passages communicating between regions.
