Title:
FLUID CONTROL VALVE AND FLOW PASSAGE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/198379
Kind Code:
A1
Abstract:
Provided are: a fluid control valve which, although configured compact and lightweight, can be utilized as a three-way valve; and a flow passage control system provided with the fluid control valve. The fluid control valve is provided with: a valve body which has a first magnetic body; a housing; an inflow passage; a first outflow passage; a second outflow passage; a second magnetic body which is disposed on one side of a containing chamber; and a solenoid. The housing is provided with: a first valve seat with which the annular front surface of the valve body, the annular front surface facing the first outflow passage, comes into contact when the solenoid is energized to cause the first magnetic body to be attracted by the second magnetic body; and a second valve seat with which the annular rear surface of the valve body, the annular rear surface facing the second outflow passage, comes into contact when the solenoid is de-energized to subject the valve body to fluid pressure in the inflow passage and thereby move the valve body to the other side of the containing chamber.
