Title: Extremely-low speed/high-torque type piston pump/motor suppressed in friction loss and leakage of working fluid
Inventor: WATABE TOMIJI
IPC: F03C1/06
Filed: 2017-05-15
Abstract: To provide a piston pump/motor which can be operated at a low speed and high torque.SOLUTION: In a piston, static pressure bearings having self-equilibrium characteristics are added to a shoe and the piston. A wave power generation device is thus expected. A plurality of static pressure bearing pads are installed at the piston of a hydraulic transmission pump, and an optimum piston motion is automatically performed due to mutual actions of the pads. The piston is stroked by a cam motion, and operates the pump. Since a clearance is formed of a vertical component of a cam at a cylinder part of a part of the piston, and the clearance becomes a leakage passage of high-pressure oil, a particular pressure distribution which is formed of an oil film is generated at a piston face. By using the particular distribution, a friction force generated at the piston face is offset. Then, a plurality of the static pressure bearings are installed at a slide face of the shoe, a variation of a bearing force occurs when oil film thicknesses are changed, and the moment in a direction in which the oil film thicknesses are restored to uniform thicknesses acts on the shoe, thus automatically restoring the piston and the shoe to equilibrium states.SELECTED DRAWING: Figure 4-1
