<p>PURPOSE:To prevent the floating of a bearing by dividing plungers into the first plungers coupled with a swash plate and the second plungers discharging a medium, and changing the return position of the second plungers to change the stroke quantity. CONSTITUTION:The first plungers 30 are inserted into multiple cylinder bores 28 arranged at a uniform interval on the first cylinder main body 14 respectively, and the second plungers 36 are inserted into the same number of cylinder bores 34 arranged on the second cylinder main body 20 respectively. The first plungers 30 on the swash plate 46 side are excited into contact with the plate 52 of a thrust bearing 48 by springs 54, and the second plungers 36 determining the discharge quantity are excited into contact with the first plungers 30 by springs 56. When a stopper pin 72 is driven to the right and the return position of the second plungers 36 is moved to the right side to control the discharge quantity, even if gaps are generated between both plungers 30, 36, the contact between the first plungers 30 and the plate 52 can be maintained.</p> |
