1. A wheel valve assembly comprising:
- a body portion having a wall defining a bottom surface, wherein the body portion comprises a protuberance axially extending from the wall;
a cover portion coupled with said body portion;
a diaphragm disposed between said body portion and said cover portion, wherein the diaphragm includes a first axially extending protrusion defining a surface which selectively sealingly engages the protuberance;
a control cavity defined by said body portion and said diaphragm;
a cover cavity defined by said cover portion and said diaphragm;
at least one control port in fluid communication with said control cavity;
a tire port in selective fluid communication with said control cavity, wherein the tire port is disposed in the bottom surface of the wall and the at least one control port is disposed through the wall, and wherein the at least one control port is in selective communication with the tire port via the control cavity and the diaphragm; and
wherein said cover portion defines an aperture in fluid communication with an atmosphere and said cover cavity, wherein a vent assembly with one or more chamfered edges is disposed in the aperture, wherein said vent assembly impedes water and debris and said vent assembly is coupled with said cover portion, and wherein said vent assembly includes at least one resilient member, wherein said resilient member has a tab for coupling said vent assembly with said cover portion.
