Abstract (en)

[origin: EP0209497A2] The apparatus comprises an electromagnet (3) for cutting off the fuel supply, controlled by a control device (7) for detecting the pressure in the induction manifold (5) of the engine. This control device (7) comprises a rigid casing (10) communicating with the induction manifold (5) of the engine, an electrical control switch (17, 18) for the electromagnet (3) having a movable control member (18) in the casing (10), an aneroid capsule (13) and a capsule (23) having a calibrated hole (24), disposed mechanically in series in the casing (10). These capsules (13, 23) cooperate with each other and act on the movable member (18) of the switch (17, 18) so that the movements of this member (18) are substantially equal to the sum of a first movement proportional to the absolute pressure in the casing (10) (and hence in the induction manifold), and a second movement substantially proportional to the temporal derivative of the pressure in the casing (10).
