Abstract

PURPOSE: To reduce impact when a plunger is adsorbed, by increasing further compressive force characteristics of a return spring near adhesion length to reduce difference between suction force of a solenoid and the compressive force of this return spring in a stroke end of a spool.
CONSTITUTION: Return springs 8, 8' are constituted to have pitch spaces varied with the position and nonlinea compression characteristics to approximate to suction froce characteristics of a solenoid 2. Thus, since the difference between the suction force of solenoids 2, 2' and the compressive force of the return springs 8, 8' near stroke end of a spool 5 is small, impact produced when abutting end surfaces 9a, 9a' of plungers 9, 9' collide with adsorption surfaces 7b, 7b' of fixed iron cores 7, 7' can be remarkably reduced.
