<p>PROBLEM TO BE SOLVED: To reduce an eccentric load of a thrust load acted on front and rear directions toward one direction by leading pressure for countervailing compression reaction acted on a piston of a compression side, to a cylinder bore of a guide side. SOLUTION: For example, six pair of front side cylinder bores 9a for housing a guide piston are formed. Elliptic intake pressure chambers 51 are formed on a front housing 50 so as to connect two cylinder bores 9a to each other, and delivery pressure chambers 52 are formed on a position corresponding to two cylinder bores 9a. The intake pressure chambers 51 are communicated with swash plate chambers through communicating passages 56, and the delivery pressure chambers 52 are communicated with the delivery pressure chambers of rear sides through communicating passages 53 and bolt holes 38a. When a compressor is operated, each inside of the cylinder bores 9a directly connected to the intake pressure chambers 51 is held to low pressure, and each inside of the cylinder bores 9a directly connected to the delivery pressure chambers 52 is held to delivery pressure. By this pressure condition, inner pressure is stabilized, and a balance between thrust loads is stabilized.</p> |
