Abstract

An arrangement for controlling the feed to the carburetor of an engine, includes connecting the inlet ports (10 to 13) to a pneumatic actuating device (19) by small bore pipes (3, 5, 7, 9). The pipes are supported by a rubber flange (1) which fits between the carburetor and the inlet manifold. The pipes (2, 4, 6, 8) emerging from the support (1) are connected to corresponding supply points. The pneumatic actuator has a flexible diaphragm (30). The spring (34) which tends to keep the diaphragm over the hole (40) is counteracted by the depression downstream of the butterfly valve (29) acting on the underside of the diaphragm. At low speeds the diaphragm (30) is pulled downwards, allowing atmospheric air to flow through the ports (38, 39) and out through the outlets (20, 21) to the inlet manifold and stratifying the air fuel mixture.
