Abstract

PURPOSE:To improve the control characteristics by providing a long groove formed with control edges having are sections extending along a whole length of the groove. CONSTITUTION:A spool valve 1 with control edges made of a single arc is constituted with the first control edge 9 and the second control edge 10, and both of them extend along almost a whole length of the long groove of the spool valve 1. Accordingly, the control characteristics of the spool valve 1 can be approached to an approximately desired characteristic curve.
