Abstract
Fuel supply system (1) for internal combustion engines, arranged in a suction channel (2) leading to the engine body proper, the system (1) comprising one or several air-regulating valves (5,6) and one or several nozzles (3,3'). A cavity (7) or channel is provided in the wall of the suction channel (2) and is positioned in such a manner that when the air-regulating valve (5,6) assumes its closed position the cavity or the channel creates a communication path (21) from one side of the air-regulating valve to the other one, and in that an at least partly movable body (8) is positioned adjacent the cavity (7) or channels in such a manner as to be able to affect the through-flow resistance in the communication path (21). The position of the movable body (8) is controlled by a temperature-responsive member (9), for instance a bimetal element.
