Abstract

A solenoid valve assembly having a valve member, disposed in a casing, movable between first and second positions for controlling communication between an inlet port and an outlet port provided in the casing which includes an armature of magnetic material operatively connected with the valve member, a leaf spring fixed at a first end thereof to the armature and biasing the valve member to the first position, a spring retainer having a first end portion which retains a second end of the leaf spring and which is stationarily fixed at a second end portion thereof to the casing, a stationary core of magnetic material mounted in the casing and operatively engageable with the armature and a mechanism acting on the stationary core and the armature for rotating the armature towards the stationary core whereby the valve is moved to the second position and an adjusting mechanism connected to the casing for adjusting tensioning of the leaf spring.
