Two-position latching electromagnetic valve of liquid-pressurised pipe systems e.g. for space flight vehicles drive systems

摘要

The valve has its inlet (2) and outlet (3) at opposite ends of its housing (1) which encloses a hollow cylindrical armature (6) with a central annular ferromagnetic projection (8) movable axially in the gap between two coils (4,5). The armature extends into a plunger (9) carrying a sealing head (10) and bellows (11) at the outlet end. The inlet end is terminated with a flange (17) and another bellows (16). At each end a main spring washer (21) is provided with a subsidiary spring washer (22) sliding along it in the same annular space (19).
