Abstract
An apparatus and method for recovering vapor during the dispensing of gasoline via a hose into a vehicle tank, according to which a turbine disposed in a vapor passage and is activated in response to the dispensing of the gasoline for drawing the vapor from the tank and into the vapor passage. Blades on the turbine separate the air from the gasoline vapor. The vapor is returned to the liquid stream and the air discharged to atmosphere. The apparatus therefore does not require vapor return piping to the underground tanks.
