ABSTRACT:
A vapor recovery adapter has a housing supported on a storage tank having a volatile liquid therein. The housing is connected to other tanks, which also are vented by the adapter in addition to the tank on which the housing is mounted, through an inlet port perpendicular to an inlet port communicating with the tank on which the housing is mounted. Diametrically disposed to the inlet port to the other tanks is a first outlet port through which all of the tanks are vented when not being filled and through which any of the tanks can receive air when liquid is being withdrawn therefrom. The first outlet port is blocked by slidable valve means in the housing when any tank is to be filled and a second outlet port at the top of the housing is opened to allow the vapor to be vented from any tank being filled to a truck tank from which the tank is being filled so that there is no exhaust of vapor to the atmosphere.
