ABSTRACT:
To reliably permit closing of a switch controlling operation of a fuel supply pump which provides pressurized fuel to a fuel injection system, even under low air flow conditions in the induction pipe of an internal combustion engine, an auxiliary spring is arranged to counteract the force of a reset spring against which a deflection flap or disk in the induction pipe of the engine is deflectable. The auxiliary spring is active only over a limited range of deflection, from rest position, and immediately adjacent thereto, so that the fuel pump will not be dis-connected under low air flow conditions.
