Abstract
An improvement of an electromagnetic valve apparatus, in which a fluid passage is opened or closed by a movable iron core. The invention provides a hand-operated transfer device having a flat spring member with a large diameter annular element and a small diameter annular element, and an extended element which is connected with both annular elements at one portion. A hand operated member has an inner end which contacts an end of the extended element and is operable from the other end from the outside of the valve. Operation of the member results in movement of the iron core by the small diameter annular element.
