<p>PCT No. PCT/FR94/00060 Sec. 371 Date Jan. 25, 1994 Sec. 102(e) Date Jan. 25, 1994 PCT Filed Jan. 19, 1994 PCT Pub. No. WO94/18044 PCT Pub. Date Aug. 18, 1994.This three-way pneumatic solenoid valve comprises: a first inlet (1) connected to a first pressure source (A); a second inlet (2) connected to a second pressure source (D); an outlet (3) connected to a chamber at controlled pressure (C); a hollow body (4) into which t here emerges each of the paths so as to be set in communication therein in a selective fashion with at least one other path; and an electromagnet (5) secured to the body and including a core plunger (5a) capable of actuating means suitable for establishing the selective communication. The latter essentially comprise a stationary valve (6) and a movable valve (7) housed in the hollow body, the stationary valve being capable of being open when the movable valve is closed and vice-versa, and these valves being defined by a shaft (60), a tubular and movable stopper member (67), and a sealed surface (70) actuated by the electromagnet. This solenoid valve makes it possible to control the pressure in the chamber (C) as a function of the pressures of the first and second sources, in proportion to a control current signal from the electromagnet.</p> |
