Patent ID: 8430114

Claim:
A vent assembly connectable to a transmission housing, comprising: a stem having a first end, a second end, an annular flange, and a through bore extending between the first end and the second end, wherein the first end is adapted to be attached to the transmission housing, and the second end has at least one flange and an annular rim, wherein the at least one flange projects axially from the annular rim, and wherein the annular flange is disposed around an outer surface of the stem proximate the second end; a membrane located on the second end of the stem over the bore, wherein the at least one flange positions the membrane over the bore; and a cap having a base and an annular wall extending from the base to a terminal end, wherein the base of the cap covers the second end of the stem, wherein the annular wall of the cap is deformed at the terminal end against the annular flange of the stem at discrete locations, and wherein an undeformed portion of the annular wall of the cap creates at least one axially extending channel, wherein the at least one channel creates a path between the cap and the annular flange of the stem that allows fluid to exit the cap and substantially prevents fluid from re-entering the cap.
