<p>PURPOSE:To make is possible to surely cool and lubricate a thrust bearing with the use of sucked coolant by forming a suction passage communicating between a suction passage chamber into which fluid flows and a suction chamber, in a cylinder housing, and by opening one end of the suction passage to a required part. CONSTITUTION:When a shaft 1 is rotated, a swash plate 2 swings while pistons 4 reciprocate in cylinder chambers 10 by means of a plurality of shoes 36, 37. Accordingly, coolant introduced into a suction passage chamber 53 from a suction communication port 50 is sucked into a plurality of suction chambers 9, 40 through a plurality of suction holes 38, 39, and is then discharged into a plurality of discharge chambers 43, 8 after being introduced into a plurality of working chambers 5, 6 through a plurality of suction holes 38, 39. In this arrangement, coolant is allowed to pass successively through the slide parts of the swash plate 2 and the shoes 36, 37, and a plurality thrust bearings 26, 27 disposed in the support part 3 and locking part 29 of the shaft 1.</p> |
