Abstract
A constant velocity joint vent for use in a constant velocity joint of an automotive vehicle. The constant velocity joint vent includes a body generally having a cylindrical shape. The constant velocity joint vent also includes a first axial channel on an inside surface of the body. A semi circumferential channel is in communication with the first axial channel on one end thereof also on the inside surface of the body. A second axial channel in communication with the semi circumferential channel on another end thereof. The vent also includes a diaphragm in communication with the second axial channel and the outer atmosphere. The vent will operate such that high pressure and high temperature gases are vented to the outer atmosphere while any contaminants or water are repelled from entering the constant velocity joint chamber.
