Abstract
PURPOSE: To effectively prevent internal leakage by applying relatively higher pressure to the back side of the valve body proportional with increasing pressure of the liquid to be shut out and raising the sealing performance.
CONSTITUTION: When current is supplied to the coil of the solenoid 38 of a three directional valve, the first seating valve 48 opens and the second seating valve 66 closes. Therefore, the pressure in pressure changing chamber 20 becomes higher, and the high pressure is supplied to the operating room connected to the connection port 28. Under this condition, the lead valve 58 of the second seating valve 66 is strongly pressed to the valve seat 64 by the high pressure acting on the back side and effectively prevent the leakage of fluid in the pressure changing chamber 20 into the low pressure chamber 22.
