囲第(3)項に記載の流体の圧力切換装置。[Claims for Utility Model Registration] (1) A valve mechanism that has a fluid inlet and an outlet and reduces the pressure of the fluid flowing into the inlet to a pressure determined by the force of a spring, and the valve a mechanism coupled to a mechanism for selectively switching the deflection of the spring between two values. (2) The valve mechanism includes a valve body having a flow path flowing toward the inflow port and the outflow port, a valve body movably disposed on the valve body to open and close the flow path, and the valve body. a first spring that applies a force to the valve element in a direction in which the body closes the flow path; a movable body that defines a communicating chamber and is moved in the direction of movement of the valve body by pressure within the chamber, and a movable body that moves the valve body in a direction in which the valve body opens the flow path; The fluid pressure switching device according to claim 1, which is a direct-acting pressure reducing valve that includes a second spring that applies a force for moving a body to the movable body. (3) The switching mechanism is connected to a cylinder tube attached to the valve body, a piston movably disposed within the cylinder tube, and is connected to the piston, and as the piston moves, the switching mechanism 2. The fluid pressure switching device according to claim (2), which is a cylinder mechanism comprising a piston rod that changes the amount of deflection of a spring. (4) The fluid pressure switching device according to claim (3), wherein the switching mechanism includes means for adjusting the movement range of the piston.
