Abstract

PURPOSE: To obtain the hydraulic pressure proportional magnetic valve which has a simple structure and enables control and adjustment of the control cycle and the flow rate of working fluid in proportion to the electrical signal inputted, without being influenced by the pressure of the working fluid.
CONSTITUTION: A proportional magnet 1, end cover 21a having an adjusting spool 3 and an adjusting spring 10 built-in, and the body 21 which is equipped with each port and into which a control sheet valve 19 is inserted area arranged in tandem. The adjusting spool 3 is inserted into a housing 4 the position of which is adjustable by an adjusting screw 6, and the lower edge are of the adjusting spool 3 is brought into contact with the upper edge of a magnet plunger 2. A feedback pin 17 is fitted in the upper area of the adjusting spring chamber 15 in which an adjusting spring 10 is accomodated, and the lower edge of the pin 17 is brought into contact with the adjusting spring 10 through a washer 11, and the upper edge is brought into contact with the lower surface of the control sheet valve 19 urged by a valve spring 18.
