Abstract: An apparatus and method for producing air flow in a vehicle that uses a cooling fan for an engine of the vehicle. The cooling fan has plurality of blades, which define an outer perimeter of the fan. The apparatus also includes a housing surrounding at least a portion of the outer perimeter of the fan and a plurality of vanes between the housing and the fan. The vanes are revolved around the outer perimeter of the fan to direct air into the housing.

Abstract: A fluid flow check valve assembly having a tubular valve housing with opposite inlet and outlet end portions and a movable valve member therebetween. The valve member has an end sealing portion engageable with an inlet seating portion of the housing and a flexible annular lip seal portion engageable with the inner wall of the housing. When the assembly is in a first pre-assembly condition which exists prior to insertion of the end of a mating outlet tube into the housing, the valve member assumes a mid-portion in the housing spaced away from the inlet seating portion. In this pre-assembled condition, the valve member's lip seal portion is seated against the inner wall of the housing thereby blocking fluid flow through the check valve assembly. The insertion of an outlet tube into the housing moves the valve member from the preassembly mid-position toward the inlet end of the housing and into a second one-way controlled flow condition.

Abstract: Connector construction for attachment of a tube to a conduit that has inlet fitting for reception of an end of the tube. The fitting has an opening normal to the inlet fitting to receive a U-shaped spring keeper in selected positions representing a preassembly position, an intermediate position, and an assembled position. Detents on arms of the spring keeper engage guide tracks in the wall of the opening to guide and yieldably hold the keeper in the three positions. Dog-leg ends of arms of the keeper secures the keeper and the tube in an assembled position in the inlet fitting. A semi-cylindrical opening formed in the keeper engages a collar or flanged portion of the tube to ensure that the tube is retained in its axially installed position.

Abstract: A one piece plastic vent cap having its open end adapted for receiving one end of a flexible hollow conduit with the conduit other end connected to a vent hole in a housing enclosing a vehicle component. The vent cap closed end if formed a central stem element projecting axially therefrom with a plurality of radial ribs interconnecting the stem element with the cap cylindrical side wall. The ribs are L-shaped defining with the central stem element a concentric space adapted for flexibly receiving one end of the conduit with the stem element telescoped within the conduit passage. Upon the conduit being inserted in the cap the conduit internal and external surfaces cooperate with the cap structure to define axial inner and outer flow passages communicating with a crossover flow passage allowing ventilation of the housing to the atmosphere.

Abstract: A regulating mechanism for maintaining a preselected pressure within the fuel rail portion of a fuel injection system of an internal combustion engine. The regulator has a cannister with a hollow interior which is divided into a biasing chamber and a fuel chamber by a diaphragm assembly. The diaphragm assembly includes a molded diaphragm having a centrally located socket containing a truncated spherical ball. Centrally disposed coaxial tubular members define concentric fuel inlet and outlet passageways communicating with the interior of the fuel chamber. The inner tubular member defines the fuel outlet passageway and has a valve seat which is normally closed by the truncated surface of the spherical ball, subject to being opened by excessive fuel pressure against the fuel chamber side of the diaphragm.
