Abstract:
The present invention prevents opening of a unidirectional flow control valve caused by an increase in the pressure in a sub port. A solenoid valve controls a flow rate of working oil flowing from a main port to a sub port, and includes: a main valve that enables communication between the main port and the sub port; a control pressure chamber that biases the main valve in a direction of closing the main valve; a first valve body provided in a main port communication passage that enables communication between the main port and the control pressure chamber; and a second valve body provided in a sub port communication passage that enables communication between the sub port and the control pressure chamber.

Claim (Index 1):
A unidirectional flow control valve capable of controlling a flow rate of a working fluid flowing from a main port to a sub port, the unidirectional flow control valve comprising:\n a main valve configured to enable communication between the main port and the sub port; a control pressure chamber configured to bias the main valve in a direction of closing the main valve; a main port communication passage configured to enable communication between the main port and the control pressure chamber; a sub port communication passage configured to enable communication between the sub port and the control pressure chamber; a first valve body provided in the main port communication passage, the first valve body being configured to permit only a flow of the working fluid from the main port to the control pressure chamber; a second valve body provided in the sub port communication passage, the second valve body being configured to permit only a flow of the working fluid from the sub port to the control pressure chamber; and a solenoid unit configured to control an opening degree for communication between the control pressure chamber and the sub port.
