Document Type and Number:
Japanese Patent JP3437595
Kind Code:
B2
Abstract:
PURPOSE: To surely hold a swash plate in a casing at the stable state in a variable-displacement swash plate hydraulic rotating machine.
CONSTITUTION: A swash plate 29 is formed into a shape having a smooth face 29A and its back face in parallel. The swash plate 29 and the fulcrum of a tilt control plate 33 holding the swash plate 29 are located on the shrinkage side of a piston 27 than the application point of the pressing resultant force F of the piston 27, and a tilt control piston 37 is located on the extension side of the piston 27 than the fulcrum position. The swash plate 29 can be surely tilted and held on the tilt control plate 33 even at the minimum tilt angle of the swash plate 29.
