Abstract
A apparatus (10) for enabling the discharge of air and vapor from the head space of a fuel tank while preventing the discharge of liquid therethrough, has an inlet (12) in communication with the head space and an outlet (14) in connection with atmosphere. The apparatus has an internal chamber (22). A body (54) is positioned above an orifice (44) in a retainer (36) inside the chamber. A relief element (72) with an opening (74) therethrough is positioned between the body and the outlet. When air and vapor flow through the device, Bernoulli's Principle causes the body to be suspended between the orifice and the opening in the relief element. When liquid enters the chamber, the body floats upward in the liquid and if the chamber fills with liquid, blocks the opening to prevent the discharge of liquid from the device. Liquid prevented from flowing out of chamber 22, flows back into the fuel tank when fluid is no longer being delivered into the device.
