PROBLEM TO BE SOLVED: To suppress vibration emanating from a track-ring and reduce a force required to displace the track-ring by providing fixed dampingly contacting means or the like which resists the action of a piston to the track-ring supporting the piston. SOLUTION: A hydrostatic machine 1 is provided with a plurality of housing elements 3 which are fitted closely to each other so as to form an inside chamber 7. A piston valve 20 is supported on the housing element 3. Also, a shaft 10 is connected to a cylinder barrel 29 through a coupling 26, and the cylinder barrel 29 is supported on a piston valve 20 and includes many cylinders 47. In addition, each cylinder 47 contains pistons 50 and installed on a slipper 51 with rivets 52, and the slipper 51 is fitted closely to an annular surface 62 of a track-ring 63. Then, a damping member 80 is disposed in a recessed part 83 of the housing element 3, and comprises a first supporting surface 81 and an outer surface 82. on the other hand, a track-ring 63 comprises a portion 87 expanding in outer radial direction which forms a second supporting surface 88. |
