摘要：A trochoid pump is constructed so that it has a deaerating hole H that
communicates with the outside, the hole H being formed on the groove bottom face 10eof the rotor casing in which a trochoid gear T is accommodated. The pump includes innerand outer rotors 12 and 13 with engaging teeth 12a and 13a, which define variable
capacity pump spaces 18. The deaerating hole H is formed at a position that is closed bythe front side edge, in the direction of rotation at a time when a pump space PR hasreached the reached its maximum capacity and vaporized fuel is exhausted when thepump space is about to decrease its capacity. The trochoid pump can suppress
generation of a vapor lock phenomenon based on a rise in the fuel temperature withoutloss of pump efficiency.
