Abstract

PURPOSE: To prevent yielding of flow-force by preparing a plate forming ports between large diameter end walls of the spool and making fluid to flow out almost perpendicular to the spool axle.
CONSTITUTION: The spool 1 is movably inserted in the body 2 as valve casing and the flow of the liquid is throttled between a separation 5 projectingly installed to the inner wall of the body 2 and a large diameter end wall 1a of the spool 1. And a plate 19 forming three ports 18 between the large diameter end wall 1a of the spool 1 is installed so that to be parallel to the large diameter end wall 1a through three attaching portions 19a on the spool 1 so that to be parallel with the large diameter end wall 1a. Therefore, the fluid is to flow out almost perpendicularly to the axis of the spool 1, and the generation of the flow-force can sufficiently be reduced.
