Claims

[Scope of utility model registration request]

A valve housing having two ports each communicating with a passage through which high-pressure fluid and low-pressure fluid flow, a valve hole through which each port opens, and an inner hole coaxial with the valve hole; A valve body is housed in the valve hole and controls opening and closing between the two ports by displacement, a solenoid to which a control current is applied, and an attractive force generated by the current applied to this valve body displaces the inner hole to open and close the two ports. a cylindrical movable core that operates a valve body and has a plurality of through holes passing through the center hole in a radial direction; a guide shaft that is inserted through the center hole of the movable core;
An electromagnetic proportional control valve comprising: a plurality of balls housed in the through hole of the movable core so as to be in contact with the outer periphery of the guide shaft and the inner hole of the valve housing.
