A one-piece vent cap adapted to be received on one end of a flexible hollow elastomeric tubular conduit having a cylindrical cross section, said tubular conduit having the other end thereof sealingly connected to a vent hole in a housing enclosing an automotive component, said one-piece vent cap comprising:
- an integrally formed flexible elastomeric cup-shaped vent cap having a cylindrical outer wall closed at one end thereof by an end wall, a central stem element projecting from said end wall inner surface thereof such that the symmetrical axis of said stem element coincides with the principal axis of said vent cap;
- said stem element comprising a pair of mirror image posts with each said post having a semi-circular cross section, said pair of posts disposed in spaced opposed relation on either side of a first transverse plane of symmetry which includes said vent cup principal axis, said pair of posts having two opposite outer semi-cylindrical surfaces and two opposing inner planar parallel surfaces interconnected by an axially coextensive web, said web defining a second plane oriented normal to said first plane whereby said web portion and said opposed inner surfaces define a pair of axially coextensive oppositely facing central stem channels;
- four uniformly spaced axially extending radial L-shaped ribs radiating from the principal axis of said vent cap, each said L-shaped rib comprising an axial leg portion and a radial foot, each said post semi-cylindrical outer surface joining radially inner vertical edge portions of an adjacent pair of said foot sections, said outer wall joining radially outer vertical edge portions of each said leg portion, whereby inner peripheral edge portions of the leg portions thereof and its associated post defining therebetween an intermediate concentric space having a predetermined radial extent adapted for fixedly receiving one end of the flexible hollow conduit therein, and whereby each said foot portion defining a radial inner edge providing a stop adapted to position said conduit one end in a predetermined axially spaced relation with said end wall, said end wall defining with said conduit free end two crossover radial passages;
- each pair of adjacent ribs defining with said vent cap outer wall a pair of diametrically opposed arcuate sectioned axially extending outer channels;
- said hollow conduit having a central passage of circular section sized to telescopically receive said pair of posts therein in a snug-fit manner, whereby said conduit central passage inner surface thereof defining with said pair of central stem channels a pair of sealed axially extending inner air passages and said conduit outer surface thereof defining with said pair of outer channels a pair of outer venting passages, such that said pair of crossover radial passages providing air flow communication between associated inner venting passages and associated outer venting passages so as to provide venting of said housing with the atmosphere.
