Abstract

PURPOSE: To eliminate mechanical cutting process thus to reduce the production cost, by opening one end of oil path switching groove and pressure inserting a separate ring into said open mouth then integrally molding through casting, forging, sintered alloy, etc.
CONSTITUTION: Axially extending port section 20 is formed on inner circumferential face of valve sleeve 15 where one axial end of said port section 20 is opened. Ring 22 is pressure inserted into large diameter ring step section 21 formed while contacting with open end 20a of port section 20 to choke the opening of port section 20. Consequently when integrally molding a sleeve 15 having port section 20 and land section 23 with casting, forging or sintered alloy, splitted mold isn't required enabling axial demolding. One axial end of groove section 24 formed on outer circumference of valve rotor 14 is also opened, where ring 25 is pressure inserted into circular step 21a while contacting with said open end 24a enabling the integral molding.
