  • Vapor exhaust system
    Patent number: 5123817
    Abstract: A vapor exhaust system including a volumeter 5 to which an air pump 7 has been coupled mechanically so that the volume of a certain amount of pumped liquid corresponds to the amount of air pumped from a fuel tank. A translatory or rotary motion provides the signal to maintain this correspondence, in which case the drive shaft 10 of the volumeter 5 is coupled to the air pump which may be executed as a gear pump. If desired, the coupling may be executed as a gear transmission 22.
