VALVE TIMING ADJUSTABLE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a valve timing adjustable device capable of enhancing workability at assembling of a chip seal without affecting the process at manufacturing a metal plate spring and a chip seal. SOLUTION: The valve timing adjustable device is installed in a drive force transmitting system to transmit the rotation force to a camshaft equipped with a cam to open and close a valve. A hydraulic chamber to make relative rotation between a case at an input side for the camshaft and a rotor at an output side to the camshaft is formed between the case and the rotor. The case and the rotor generate the relative revolution by controlling hydraulic pressure for the hydraulic chamber so as to changer the rotation phase of the camshaft, and change the opening and changing timing of the valve. The chip seal and the plate spring attached to the case or the rotor to seal the hydraulic chamber are integrally formed made of a metal plate by plate working. COPYRIGHT: (C)2005,JPO&NCIPI
