の斜板式ポンプ・モータ。[Scope of claims for utility model registration] (1) Cylinder block 4 and shaft 6 in case 1
A piston 12 is fitted into the cylinder hole 11 of the cylinder block 4 to form a cylinder chamber 13, and the cylinder chamber 13 is successively communicated with the high pressure port and the low pressure port of the valve plate 15. In a swash plate type pump/motor in which a piston shoe 16 connected to a piston 12 is slidably pressed by a shoe retainer 17 along the front surface of a rocker cam 18, a retainer guide 38 is integrally formed in the center of the cylinder block 4. The guide surface 38a of the retainer guide 38 is connected to the cylinder block 4.
The piston shoe 16 is pressed against the front surface of the rocker cam 18 by the retainer guide 17 by pressing the elastic piece 43 provided on the shoe retainer 17 onto the guide surface 38a, and the cylinder block 4 is pressed against the front surface of the rocker cam 18. A pump/motor which is in pressure contact with the valve plate 15, and furthermore, the cylinder block support center is made to coincide with the center of action of the writhing force caused by the thrust of the piston. (2) The swash plate type pump/motor according to claim 1, wherein the rocker cam oscillation center and the cylinder block 4 are aligned.
