Document Type and Number:
Japanese Patent JPS60205083
Kind Code:
A
Abstract:
PURPOSE:To make the opening or closing of a valve yet more nimble, by installing a hole, interconnecting the inflow port side of a valve body to each inner side of a cylinder member and a piston member, in a valve block. CONSTITUTION:A valve body 1 is provided with a flow passage 5 interconnecting an inflow port 2 to an outflow port 3, and such a valve seat 8 as being dividable into the inflow port side 6 and the outflow port side 7 is formed in this flow passage. Inside a cylinder member 13, a tubular piston member 14 being of almost equal diameter to an opening diameter of the valve seat 8 is slidably made into taction. And, since plural small holes 24 capable of interconnecting the inflow port side 6 to the inner side 23 of both these cylinder and piston members 13 and 14 are installed in a valve block 16, both upper and lower forces of the valve block 16 are almost balanced.
