ABSTRACT:
A device for mounting in a fuel dispensing hose that has a flexible inner tube defining the fuel conduit, and a tubular outer sleeve that defines with the inner tube an annular vapor return passage. The device includes a venturi section adapted for serial connection with the inner tube within the outer sleeve. The section comprises a cylindrical block that connects at each end with an end of the inner tube and defines a venturi forming part of the fuel conduit. The block also has an aspirator means that defines at least two radial ports communicating between the venturi throat and the annular vapor passage. Each radial port has a check valve to block fuel flow from the fuel conduit to the vapor passage.
