Claims

[Scope of utility model registration request]

A main valve seat is provided in the main fluid passage, and a main valve element that opens and closes the main fluid passage is provided so as to face the main valve seat so as to be able to come into contact with and be separated from the main valve seat. A sub-fluid passage is provided that connects a high pressure side and a low-pressure side of the main fluid passage, and a sub-valve seat is provided in the sub-fluid passage on the main valve body, and the sub-valve seat can be moved into and out of contact with the sub-valve seat. A sub-valve body for opening and closing the sub-fluid passage is provided opposite to the sub-valve body, the opening area of the sub-fluid passage at the sub-valve seat is set smaller than the opening area of the main fluid passage at the main valve seat, and further, the main valve body and a flow path opening/closing solenoid valve provided with a holding member that holds the sub-valve body in a closed state and an electromagnet that opens the main valve body after opening the sub-valve body.
