<p>A three-way magnetic valve as a switching device for refrigerators with two different temperature compartments operated with only one refrigeration machine, has an axial bore hole in a tubular housing with an inlet to the bore hole of the housing and an outlet at each end of the housing, a rod-like plunger with a sealing member at end, axially movable in the bore hole so as to seal one end and open the other end and vice versa, a coil of an electro-magnet mounted on the housing, an armature axially movable in the housing to engage and move, when energized, the plunger against the restoring force of a spring. A damping spring is also provided. The valve is simple in design, less expensive, smaller in dimensions, and is substantially trouble-free for long periods of time.</p> |
