摘要

a device for fu00fcllbegrenzung and ventilation of containers, in particular fuel tanks of motor vehicles, with a part of the behu00e4ltervolumens as druckausgleichsraum in relation to temperature, is has a in the loading and entlu00fcftbaren einfu00fcllstut zen professionals working and gas extractor, one of the qualifying max.fluid level determining fu00fcllentlu00fcftung and the ventilation of the druckausgleichsraumes acquiring betriebsentlu00fcftung with a schlieu00dfvorrichtung therewith, such that the betriebsentlu00fcftung in his cap by federwirkung locked and in the cap this myself the resilience is opened.to control the betriebsentlu00fcftung serves in the loading and entlu00fcftungsleitung integrated valve, whose valve bodies against federwiderstand through a piston rod betu00e4tigbar.the valve is so arranged that the orifice, the piston rod is parallel or substantially parallel to the sides of the einfu00fcllstutzens within the same comes to lay with its free end, and at abgehobenem cap from the orifice above.such a loading and entlu00fcftungsvorrichtung is characterized by simple and cost-effective manufacturability while great reliability. it allows the integration of otherwise advantageous as separatteil planned. roll over valve.
