| 摘要 |
<p>The invention concerns a relay for use particularly in motor-vehicles, comprising a stable ferromagnetic core (1), an excitation coil (2) wound around said core, a movable assembly composed from at least one movable ferromagnetic armature (3), a flexion foil (4) fixed in a determined point (5) of said movable armature and an exchange contact (6), said relay also includes a return spring (7) to maintain in a position of maximum air gap such armature with respect to said core when the device is in a release condition and at least one (8a, 8c) closure and/or opening contact that is activated by the movable armature (3), through its exchange contact (6), when this is drawn or released by the core (1). The main characteristic of the invention consists in the fact that it has an intermediate support element (9) for said flexion foil (4) obtained on one of the elements of the movable assembly, and that said support (9) is of such a height and is to be found at a distance from the fixing point (5) so as to produce a sensitive pre-charge of said foil (4), even before the closure. <IMAGE></p> |
