Electromagnetic valve

Abstract

There is described a ultra-miniature electromagnetic valve assembly smaller than 1 mm in diameter of inlet and outlet ports and having a valve casing of approximately of 10 mm in plan view side length, the valve assembly of the type formed by connecting separately fabricated valve casing and electromagnetic operating section and comprising: an inlet port and an outlet port provided on one side surface of the valve casing; locking projections provided on the opposite side surfaces of said valve casing; and an outer shell member for the electromagnetic operating section, having a notched portion at the inner end of one of side surfaces thereof to evade the inlet and outlet ports and provided with locking windows on the opposite sides of the notched portion and on the other side surface, the locking windows being engageable with the locking projections on the valve casing to connect the electro-magnetic section thereto. Consequently, the valve casing and electromagnetic operating section are connected to each other easily in a space-saving manner, permitting production of ultra-miniature electromagnetic valves.
