ABSTRACT:
In combination with a flow control valve assembly, an electromagnetic motor assembly includes a stationary core surrounded by a solenoid coil at its small diameter portion, a yoke member coaxially spaced from the stationary core and having an axial hole coaxial with the small diameter portion of the stationary core, and a movable core arranged between the stationary core and the yoke member. The stationary core is formed at its inner end with an annular recess, and the movable core is at its inner end with an annular projection to be coupled within the recess with a predetermined clearance.
