ABSTRACT:
A current-stroke proportional type solenoid valve has a movable plunger disposed around the inner peripheral wall of a bobbin with a coil therearound, a stator core disposed face to face with the movable plunger and forming the magnetic circuit, a bias spring for always biasing the movable plunger in one direction and the stroke of the movable plunger being determined by magnitude of the current flowing through the coil. In the solenoid valve, the output rod is axially supported by a first lubricant resin and the movable plunger also by a second lubricant resin.
