Abstract
A carburetor with an auxiliary accelerator-pump system including a diaphragm pump. The diaphragm pump includes a fuel chamber and a vacuum chamber which are separated by a spring-loaded diaphragm. The fuel chamber leads by way of a check valve to a fuel reservoir or float bowl in a carburetor and by way of another check valve to a pump jet or nozzle which is open into an intake passage in a carburetor, while the vacuum chamber leads to a vacuum take-off port open in the intake passage downstream of a throttle valve. The fuel chamber is further communicated by way of a temperature responsive valve means with the fuel reservoir, and this valve means is adapted to open, when an ambient temperature exceeds a given temperature level.
