Document Type and Number:
WIPO Patent Application WO/1999/024743
Kind Code:
A1
Abstract:
A spool valve having an axially movable spool provided with two lands at both end portions thereof, and a valve body provided coaxially with and on the outer side of the spool, the opening and closing of the valve being done in accordance with a movement of the spool, the spool valve being further provided with insert members and fragmentary members for interfering with spool driving and shutting off the flow power which make a movement of the spool unstable. Owing to the insert members, the undesirable flow power of a fluid, which flows into the valve body from one port thereof and flows out from another, exerted on the spool is shut off.
