Constant velocity joint vent valve

A constant velocity joint venting system comprising:

• a constant velocity joint having an internal chamber and a vent plate defining a vent aperture in communication with the joint chamber;
• and a vent valve receivable in the vent aperture, the vent valve comprising:
• a body having a first end and a second end and at least one straight-line vent extending therebetween;
• and
• a flexible retention cap disposed adjacent the first end of the body and the at least one straight-line vent, the straight-line vent being adapted to self clean the vent valve under the influence of rotational forces.

A vent valve for use in a constant velocity joint, comprising:

• a body having a cylindrical outer surface, a first end and a second end;
• at least one straight-line vent formed in the outer surface, and extends from the first end to the second end, the outer surface having an annular lip located adjacent the first end, an annular channel located between the annular lip and the second end, and an annular engagement surface located on the annular lip toward the annular channel, wherein a vent pathway is formed by the at least one straight-line vent and the annular channel;
• and
• a flexible retention cap disposed between the annular channel and the second end of the body, wherein the flexible retention cap is umbrella shaped covering the annular channel and has a greater circumference than the annular lip which has a greater circumference than the annular channel,
• wherein the at least one straight-line vent is adapted to self clean the vent valve under the influence of rotational forces.
