Title:
ONE-WAY FLOW CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2017/043251
Kind Code:
A1
Abstract:
In order to prevent a one-way flow control valve from opening due to a rise in pressure of a sub-port, a solenoid valve (100, 200), for controlling the flow rate of a hydraulic oil flowing from a main port (82) to a sub-port (83), is provided with a main valve (22) which communicates between the main port (82) and the sub-port (83), a control pressure chamber (42) which biases the main valve (22) in the valve-closing direction, a first valve body (71, 271) which is provided in a main port communication channel which communicates between the main port (82) and the control pressure chamber (42), and a second valve body (72, 272) which is provided in a sub-port communication channel which communicates between the sub-port (83) and the control pressure chamber (42).
