<p>A breather (18) for a driveline component such as an axle, for example, includes a rigid body portion (30) attached to an axle housing (12), an extension portion attached to the rigid body portion and extending into a housing cavity, and a conical spring supported by the extension portion. The rigid body portion has an internal bore (32) that extends from a first body end (34) to a second body end (36) with the first body (30) end extending outwardly from the axle housing (12) and the second body end (36) being fixed to the axle housing (12). The extension portion has a non-uniform cross-sectional area, and includes an extension bore with a large internal diameter. A conical spring (96) is received within the extension bore and cooperates with the extension to prevent lubricating fluid from exiting the breather (18) while still allowing air to vent through the breather (18) as needed.</p> |
