Unitary air bleed device

摘要

A unitary air bleed device of an elastomeric deformable material and has an integrally formed head portion with a vent hole and a cylindrical portion with a connecting passage formed therethrough. The connecting passage communicates with the vent hole of the head portion. The deformation of the air bleed device permits the air bleed device to be mounted to an enclosed housing by press fitting. When mounted, the cylindrical portion extends into the housing in such a direction to prevent the oil entry into the connecting passage.
