ABSTRACT:
A solenoid-actuated three-way fluid control valve having a paramagnetic valve body and a ferromagnetic adjustable end stop connected by a ferromagnetic tubular sleeve and forming a housing defining a valve chamber containing an axially elongate generally cylindrical ferromagnetic solenoid plunger supported for axial reciprocal movement between a pair of axially opposed valve seats. The plunger is biased toward seating engagement with an associated one of the seats and is moveable out of seating engagement with the one seat and into seating engagement with the other seat in response to energization of a surrounding solenoid coil. An annular ferromagnetic flux ring disposed adjacent one end of the coil cooperates with a diametrically enlarged portion of the plunger to define a portion of a flux path. The position of the end stop relative to the sleeve is adjusted during manufacture to set the clearance between the valve plunger and the one valve seat thereby enabling accurate valve calibration. A method for calibrating the valve is also disclosed.
