Abstract

PURPOSE: To obtain a spool valve which produces no sharp edge in such a way that a pipe is inserted into a spool valve main body having concave parts which conduct to ports inside, plastic deformation given by applying pressure from inside sharply reduces burden on machining.
CONSTITUTION: Proper number of concave parts 31, such as annular grooves, etc. which conduct to each port EX, CYL, etc. are formed. A pipe 32 is inserted into this main body 3, parts 33 corresponding to the concave parts are dilated by applying pressure from the inside of the pipe. And bores 34 are opened their ways from the sides of the ports, such as EX, CYL, etc., which make ports get conducted into the pipe. A spool 35 is inserted into the pipe 32 formed such as this.
