NIEDRIGDRUCK-MAGNETVENTIL

摘要

A solenoid valve utilizes a single unitary member as a combined core/spool which is axially moveable between an extended deactivated position to a retracted activated position upon actuation of its coil. The valve includes a coil in which the windings on a bobbin are encapsulated by injection molding an outer member therearound. The valve also includes a washer which becomes adhered to the outer member during injection molding, a plug member supported on the washer and a sleeve encircling the coil. The plug member has an end positioned to be contacted by the core/spool upon actuation which is contoured to provide minimal contact surface between it and the core/spool.
