Japanese Patent JPH0686867
Kind Code:
B2
Abstract:
PURPOSE:To prevent abnormal abrasion by crossing the center of the combined reaction forces caused through the pressure of fluid functioning onto a valve plate and the center of the combined pushing forces of piston each other on a plane containing a bearing. CONSTITUTION:A spherical face having a center O' on the axis of a rotary shaft 6 is employed as a sliding face 20 between a cylinder block 1 and a valve plate 2 while a bearing 7 for bearing the cylinder block 1 is arranged on a face containing a cross point O between a line connecting between the spherical end positions P1, P2 at the bottom dead center of a piston 3 and the axis of the cylinder block 1 and perpendicular thereto. Since the combined reaction forces caused through the pressure of fluid functioning onto the valve plate 2 and the combined pushing forces of the piston 3 are born by a bearing 7 for bearing the cylinder block 1, the relative attitudes of the valve plate 2 and the cylinder block 1 are maintained normally thereby the abnormal abrasion is prevented.
