ABSTRACT:
A diaphragm carburetor system includes a diaphragm-controlled closed-loop control chamber for fuel communicating through a number of fuel conduits with an aspiration conduit for air. All of the fuel conduits extend separately from one another over their entire length in order to attain the least possible acceleration delay with simultaneously high efficiency. As a result, both a main channel and an idling conduit and each partial load conduit are supplied with fuel from the control chamber. Since an entry of air is prevented both into the partial load conduit or conduits and into the idling conduit, each conduit remains completely filled with fuel during the entire period of operation, so that upon sudden acceleration events, the fuel can emerge into the aspiration conduit of the diaphragm carburetor without delay.
