摘要： An apparatus is proposed which serves to regulate the idling rpm of an internal combustion engine. The apparatus includes a bypass line bypassing an arbitrarily actuatable throttle valve in the intake tube. An electromagnetically actuatable bypass valve is disposed in the bypass line for the purpose of controlling supplementary air and is triggerable in accordance with operating characteristics of the engine. In addition, a pressure-sensing adjusting element is also provided, which responds to an abrupt reduction in the intake tube pressure downstream of the throttle device. In accordance with the magnitude of the pressure reduction, this pressure-sensing adjusting element effects a time-limited increase in the supplementary air quantity to the intake tube section downstream of the throttle valve. In the event of an abrupt reduction in the intake tube pressure downstream of the throttle valve, caused by the closure of the throttle valve subsequent to a previous, slight increase in pressure on the gas pedal, the apparatus according to the invention prevents the engine from stopping.
