    摘要: A device for the production of a fuel vapor/air mixture for spark-ignition engines comprising a float chamber and a vaporizer chamber with heated vaporizer surface, an intake pipe being provided with a first fixed diaphragm or nozzle, the liquid spaces of the vaporizer chamber and of the float chamber being connected to each other by means of a line, the gas space of the float chamber being connected upstream of the diaphragm or nozzle, viewed in the direction of flow, and the gas space of the vaporizer chamber being connected downstream of the diaphragm or of the nozzle, viewed in the direction of flow, to the intake pipe, by means of lines in each case, and the line from the gas space of the vaporizer chamber into the intake pipe being provided with a second fixed diaphragm or nozzle, which induces a pressure drop of 85 to 99.99% of the first diaphragm or nozzle, and a damping line being arranged between float chamber and vaporizer chamber at the height of the liquid level when the engine is at rest, through which line liquid can pass from the vaporizer chamber into the float chamber, or vice versa, when pressure peaks occur, without the entire liquid columns in the vaporizer chamber and float chamber having to be set in motion. This prevents fluid pulsations which may otherwise occur and make it possible for the engine to run smoothly.
