Abstract

PURPOSE:To enable to hold a valve boby at the predetermined position of opening or closing by a constitution wherein a driving signal consisting of a direct current is supplied to an electromagnetic pump during the output signal of a position detecting means is supplied. CONSTITUTION:When a responding body 39 is arrived at the predetermined position thereof by the pressure of working fluid sent under pressure by the operation of an electromagnetic pump 33, it is detected by a lead switch 43 and the driving signal supplied to the electromagnetic pump 33 at that time is changed from the signal having the pulse wave form of a predetermined frequency into the same of direct current, whereby, the plunger 55 of the electromagnetic pump 33 is stopped. However, a bypass valve 70 is held at the closing position thereof by the direct current supplied to a coil 51, therefore, the responding body 39 is also held at the position at it is located.
