Abstract

PURPOSE: To reliably control a large amount of fluid having a high-pressure, by a method wherein, at a No.1 position of a 2-port, 2-position swithcing valve, a flow from a No.1 port to a No.2 port or a reverse flow is possible, and at a No.2 position, a connection between the two ports is shut off.
CONSTITUTION: At a No.1 position whereat a solenoid 60 is demagnetized, a valve part 52a is away from a valve seat 51, whereby a part of a pressurized fluid fed to a No.1 port A flows into an inner hole 12a in a small diameter through a pilot valve 50 and a check valve 42. Thus, a No.1 spool 20 slides to the right and a No.2 spool 30 to the left through the differential pressure, and a pressurized fluid, flowing to a No.2 port B from the No.1 port A through a main path 13, becomes a free flow. At a No.2 position of the electromagnetic valve V, the pressurized fluid is not allowed to pass both orifices 20a and 30b with a valve 50 closed, and a connection between a path 13 and a port B is shut off.
