초록 ▼

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.

In a liquid dispensing hose for distributing liquid fuel from a pump to a valved nozzle adapted to be inserted into the fill pipe of a vehicle fuel tank, said hose having an inner tube defining a fuel conduit and a tubular outer sleeve that defines with said inner tube an annular passage for recovering fuel vapors from said fuel tank, the improvement comprising: a venturi section disposed in serial connection with said inner tube within said outer sleeve and comprising a cylindrical block having connecting means at each end for connecting to end portions of said inner tube and defining a venturi forming part of said fuel conduit; and aspirator means in said venturi section and defining at least three radial port means communicating between said venturi forming part and said annular vapor passage, said radial port means extending through said block at uniformly circumferentially spaced locations in a transverse plane that intersects said block at said venturi forming part, said radial port means each having an inlet means that faces directly toward said tubular outer sleeve whereby said inlet means of at least one radial port means is always located below the centerline of said venturi section when the centerline of said venturi section is disposed substantially horizontal in said liquid dispensing hose so that liquid fuel collected in said annular passage adjacent said venturi block is adapted to be drawn through said aspirator means due to suction adapted to be produced in said venturi forming part upon the flow of liquid fuel therethrough.
