Abstract (en)
[origin: EP0419352A1] The electromagnetic valve, which can be used in particular in a fuel feed system for an internal combustion engine, comprises a casing (10) containing an electromagnet with a control winding (24) and in which a passage is arranged limited by a seal (32) receiver seat (20) and having a mobile rig in the casing, displaceable between a first position towards which it is attracted by a permanent magnet (36) and another position towards which it is attracted by the electromagnet when a current is fed to the winding (24), one of the positions being defined by the support of the seal (32) on the seat (20). The mobile rig, in addition to the permanent magnet and the seal, has a core (34) of ferromagnetic material arranged so that the airgap of the circuit comprising the electromagnet and the core is at a minimum when that of the magnetic circuit comprising the permanent magnet is at a maximum, and vice versa. <IMAGE>
