ABSTRACT:
A fueling and associated vapor recovery system maintains the same, or lower, vacuum level in the vapor hose during ORVR vehicle refueling as that seen during a non-ORVR refueling. A valve assembly is made as either a part of the end of the vapor recovery hose assembly, a separate unit that is placed between the hose assembly and the nozzle, or incorporated directly into the nozzle. The valve assembly is biased to one position by a spring to which is attached a sliding valve member. The force of the spring is sufficient to keep the valve member in the original position when refueling non-ORVR vehicles so that the vapor hose is unobstructed and an air bleed hole is closed. When refueling an ORVR vehicle, the elevated vacuum level moves the valve member to a second position which blocks off the vapor hose from the vacuum pump and opens up the vapor hose to the air bleed hole.
