Abstract
The invention relates to a subpressure limiter for a fuel injection system of a mixture compressing, externally ignited internal combustion engine wherein the apportioned fuel quantity is injected into the suction tube containing an arbitrarily actuatable throttle valve, and wherein the suction tube sections upstream and downstream of the throttle valve are interconnected by means of a bypass whose cross-sectional area is variable by means of the subpressure limiter and features a pressure dependent control element responding to the subpressure prevailing within the suction tube section downstream of the throttle valve during an overrunning operation.
