Abstract
PURPOSE: To simplify the construction of a sleeve and facilitate an easy work of its machining, by forming the sleeve from a guide cylinder constructed with a thin plate as a cylindrical body having a plurality of annular grooves and a casing mold formed around said guide cylinder.
CONSTITUTION: A guide cylinder 2 that slidably guides a spool 1 is formed by a thin plate and used, so to speak, as an inner mold, then a plastic is molded around the guide cylinder 2 by the method of injection molding or the like to form a casing 3. The casing 3 and the guide cylinder 2 construct the sleeve of a spool valve as an integral unit. The casing may be formed by using a light alloy instead of plastic in the method of die casting or the like. In the casing 3, a suction port 4, the first outlet port 5, the second outlet port 6, the first discharge port 7 and the second discharge port 8 are formed.
