Abstract

PURPOSE: To increase reliability of operation performance and life by forming a valve seat member and the corresponding engaged surface of the valve plug into tapered form along the direction of engagement.
CONSTITUTION: The engaged surfaces S1 and S2 of the valve bodies 8A and 8B for switching a valve seat 7A and the corresponding pump connection port P are formed into tapered form along the direction of engagement. When the instruction pressure X from a pilot valve or the like not shown in the figure is applied to the instruction part 9, a valve rod 5 shifts downward, and the conical seal engaging surface S2 of the valve body 8A is sealed onto the valve seat 7B having a corresponding shape, and the seal engaging surface S2 of the valve body 8B is sealed onto the valve seat 7D. While, an instruction pressure Y is applied, the valve rod 5 shifts upward, and each seal engaging surface S1 of the valve bodies 8A and 8B is sealed onto the valve seats 7A and 7B respectively. Thus, superior operation is obtained without generating leakage for high pressure, and wear is reduced, and the life is improved.
