PURPOSE: A hydraulic shuttle valve is provided to reduce noise and to improve the durability. CONSTITUTION: A valve housing(1) has an oil passage(4). A valve member(5a) opens and closes the oil passage by moving inside the valve housing. A first spring(7a) operates elastic force to close the oil passage by arranging between the valve housing and the valve member. An operating pin(5b) is combined with the valve member and extended by penetrating the oil passage. A piston(6) is moved with the valve member by arranging inside the valve housing and having an inserting groove(6a). A second spring(7b) operates elastic force to open the oil passage by arranging between a cover of the valve housing and the piston. A damping member(16) reduces shock and noise by arranging between the cover and the piston. Thereby, the pleasant environment is offered and the durability is improved.
