An electromagnetic valve comprises a valve body having a dividing wall which separates a first chamber and a second chamber and a through-hole formed in the dividing wall and in which a valving element is inserted, a guide member having a main body portion disposed between an outer peripheral surface of the valving element and an inner peripheral surface of the valving element and forming a gap with the inner peripheral surface of the through-hole, an insertion hole through which the valving element is inserted and which slides against the outer peripheral surface of the valving element, a flange portion provided on an one-end side of the main body portion and being in contact with the dividing wall and a tapered portion provided in the one-end side and disposed inside the first chamber. The flange portion is pushed toward the dividing wall by a pushing member.

Electromagnetic valve

To minimize the amount of air that may enter the damper chamber in a normally closed solenoid valve to stably maintain the damper capacity, the normally closed solenoid valve has a valve housing and a movable element. A cylinder having an open end is formed in one of the valve housing and the movable element. The cylinder has an inner diameter smaller than the outer diameter of a trunk of the movable element. A piston provided on the other of the valve chamber and the movable element is movable relative to the cylinder as the movable member moves. The piston is inserted into the cylinder through its open end to define a damper chamber between the piston and the cylinder. A restricted passage is formed between the damper chamber and the valve chamber through which hydraulic fluid can be moved between the valve chamber and the damper chamber.
