Abstract:
A solenoid valve includes a main valve configured to change a communication opening degree between a first port and a second port, a control pressure chamber configured to bias the main valve in a valve closing direction, an auxiliary valve configured to open and close a first communication passage and a second communication passage formed in the main valve, a solenoid portion configured to displace the auxiliary valve, a back pressure chamber and a sub-return spring configured to bias the auxiliary valve in a valve closing direction, and a pressure compensation unit configured to change a biasing force of the sub-return spring acting on the auxiliary valve according to a pressure in the back pressure chamber.

Claim (Index 1):
A solenoid valve for controlling a flow rate of working fluid flowing from a first port to a second port, comprising:\n a main valve configured to change a communication opening degree between the first port and the second port; a control pressure chamber configured to bias the main valve in a valve closing direction by having the working fluid introduced thereto from the first port; a communication passage formed in the main valve, the communication passage being configured to allow communication between the control pressure chamber and the second port; an auxiliary valve configured to open and close the communication passage; a solenoid portion configured to displace the auxiliary valve according to a supplied current; a back pressure chamber communicating with the control pressure chamber, the back pressure chamber being configured to bias the auxiliary valve in a valve closing direction; a first biasing member housed in the back pressure chamber, the first biasing member being configured to bias the auxiliary valve in the valve closing direction; and a pressure compensation unit configured to change a biasing force of the first biasing member acting on the auxiliary valve according to a pressure in the back pressure chamber.
