Abstract

PURPOSE: To set the output pressure controlled by the spool position in accordance with the duty ratio of an input pulse by supplying the input pressure of a fixed level to an electromagnetic valve provided at the edge part of the valve body.
CONSTITUTION: When an input pulse set at an optional duty ratio is applied to an electromagnetic valve 40, the input pressure supplied to the valve 40 is varied. This varied driving pressure is supplied to one of both edge parts of a spool 31. Thus the spool 31 which is energized in the axial direction at the other end is pressed in the opposite direction and slides in accordance with the driving pressure. Then the position of the spool 31 is regulated. As a result, the spool 31 is fixed at a position where the output pressure is maintained with the feedback pressure produced between the driving pressure and the output pressure. Thus it is possible to keep a state where the output pressure is obtained by the body of the valve 40 in accordance with the duty ratio.
