The poppet valve is pivotally connected to the armature at a rear end thereof. The poppet valve has an outer diameter substantially equal to a diameter of the seat portion at an intermediate portion between the front end and the rear end. The intermediate portion is slidably inserted into the sleeve. The poppet valve has a passage formed therein for equalizing pressures applied to sides of the sleeve.
