ABSTRACT:
A device which influences the composition of the operating mixture supplied to an internal combustion engine having a suction tube and a bypass. The suction tube includes an adjustable mixture quantity control member and the bypass line includes at least one throttle member. Structure is provided to vary the adjustment of the throttle member in proportion to the adjustment of the mixture quantity control member and thereby vary the flow cross section in the bypass. A second throttle member cooperates with the other throttle member and is controlled by a control device connected to the engine to further vary the flow cross section of the bypass. Alternatively, a stylus and cam structure are provided which are utilized to produce the further variance of the flow cross section of the bypass. In this regard the stylus is controlled by the control device.
