Abstract
A fuel cut-off valve (10) includes an enlarged-diameter vapor outlet aperture (30) which is controlled by a first closure member (50) having a small auxiliary vapor vent orifice (52) which, in turn, is controlled by a second closure member (58) formed on the float member (38). The first closure member (50) is biased by a spring (62) toward the second closure member (58) to ensure that the first closure member (50) is unseated away from the main valve seat (36) as soon as the auxiliary vapor vent orifice (52) is opened.
