PURPOSE: A compressor is provided to prevent the dispersion of the sealing pressure on contact with the surface between a partition barrier wall and a head gasket by forming an increase on the surface pressure unit at the partition barrier wall partitioning in between the space forming an arbor hole and the space forming a discharge chamber of the head. CONSTITUTION: A compressor comprises a head(110,120), a valve unit(620), head gaskets(710,720), and a cylinder block(210,220) generating a plurality of cylinder bores(211,221) and swash plate chambers(213,223). The head comprises arbor holes(112,122), a plurality of discharge chambers(111,121), and a partition barrier wall. The arbor holes support a driving shaft(400). The discharge chamber is individually formed in place corresponding to the cylinder bores in a radial direction of the arbor holes. The partition barrier wall is formed in the place generating the discharge chamber and the arbor holes in order to partition each other, and opposite side against a cylinder block is supplied as contact surface for connecting the head gasket. Surface pressure unit for increasing surface pressure is formed on the wall side of the discharge chamber which is in an outer periphery of the partition barrier wall. |
