Abstract
The device is intended to overcome the increase in pressure in the float chamber (12) due to the evaporation of fuel in hot weather which causes fuel to flow into the inlet manifold. The float chamber (12) is fitted with a relief valve (2) which is held closed by the diaphragm (1) and spring (2). The chamber (4) above the diaphragm (1) is connected by a pipe (10) to the body of the carburettor near the throttle valve plate (9). Under normal running the depression at the orifice (8) is insufficient to overcome the spring (3). Under slow running the depression increases and the diaphragm (1) is lifted up to allow the vapour in the float chamber to escape through the pipe (7).
