Abstract
Vapors displaced from a volatile liquid container, such as a vehicle's fuel tank, during refilling of the container are recovered by a system employing a liquid jet gas pump to produce a suction in a vapor removal conduit. The liquid jet gas pump draws the vapors through the vapor conduit at a velocity which is sufficient to remove any liquids in the conduit, thereby preventing blockage of the conduit. Valving arrangements in the liquid jet gas pump make the system compatible with leak detection devices and regulate the vacuum in the vapor conduit to a predetermined maximum.
