Claims

[Scope of utility model registration request]

A valve housing having an input port and an output port, a shaft movable in an axial direction within a motor portion fixed to one end of the valve housing, and a movable core movable integrally with the shaft. , a valve integrally attached to the movable core so as to be able to control opening and closing of communication between the input port and the output port; and a valve having an effective area equivalent to the sealing area of the valve and having an inner peripheral edge attached to the movable core. hermetically fitted and having its outer peripheral edge hermetically attached to the valve housing;
A diaphragm that defines a back pressure chamber within the valve housing, a spring that biases a movable element including the valve in a normally closed or normally open direction of the valve, and an electromagnetic mechanism housed within the motor section. , the movable core has a hole in its center that communicates with the input port at one end, and at least one hole that communicates with the back pressure chamber at the other end, and the movable core has a hole in the center that communicates with the input port, and has at least one hole that communicates with the back pressure chamber at the other end, An electromagnetic proportional flow control valve that proportionally controls the fluid flow rate between the input and output ports according to a signal.
