VANE TYPE HYDRAULIC EQUIPMENT, MOTOR, AND VALVE TIMING CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide vane type hydraulic equipment capable of improving an energy utilization efficiency by preventing leakage of hydraulic fluid caused by the fluid flowing around an end portion of a seal member. SOLUTION: A seal groove is formed at a front edge surface of a vane of a vane rotor from one end to the other end of an axial direction. The seal groove stores a first and a second seal members 22A, 22B contacting with an inner peripheral surface of a housing, and a flat spring 31 biasing the first and the second seal members 22A, 22B. The first seal member 22A is biased with the one end of the axial direction by receiving component force of the flat spring 31. The second seal member 22B is biased with the other end of the axial direction by receiving component force of the flat spring 31. COPYRIGHT: (C)2008,JPO&INPIT
