Abstract: A locking quick connect assembly is provided for removably coupling a first tube and a second tube. A quick connect housing presents a central bore for receiving the second tube. A redundant latch component positionable between an unlocked position and a locked position may be provided to slidingly engage the quick connect housing. A twist lock retainer surrounds the quick connect housing and the redundant latch component. The redundant latch component includes an axially extending redundant latch retaining arm and the twist lock retainer includes a locking channel for receiving the redundant latch retaining arm. The twist lock retainer also includes a twist lock retaining arm that locks against a bead of the second tube to resists separation. The twist lock retaining arm extends perpendicularly to and radially inwardly of the locking channel to interleavingly engage the redundant latch retaining arm thus preventing unwanted decoupling of the assembly.

Abstract: The quick connector assembly includes an insertion member that is inserted along a longitudinal axis into a receiving member. A retaining member is disposed in the receiving member for movement in a direction of insertion that is perpendicular to the longitudinal axis. A positioning member is disposed in the receiving member and includes a biasing portion that extends angularly from a base portion to a pair of blocking portions. The blocking portions move between an extended position and a retracted position and are oriented opposite the direction of insertion of the retaining member to block the retaining member from moving into a fully inserted position when the biasing portion is in the extended position. An annular collar of the insertion member engages the blocking portions when the insertion member is axially inserted in the receiving member to move the blocking portions into the retracted position.

Abstract: A fuel system comprising a fuel tank having an opening. A cap is removably coupled to the fuel tank and operable for sealingly closing the opening to prevent ingress and egress of air through the opening. An overfill chamber is in communication with the fuel tank, and a hydrocarbon collection chamber is in communication with the overfill chamber. A valve is disposed between the hydrocarbon collection chamber and the overfill chamber. The valve includes a reference axis and is configured to permit fluid communication between the overfill chamber and the hydrocarbon collection chamber only when an angle between a vertical axis and the reference axis is less than about thirty-five degrees.

Abstract: A hydrocarbon trap that includes a sheet paper element and a plurality of fingers. The paper element is at least partially formed of a material capable of adsorbing and desorbing gaseous hydrocarbons. The paper element is arranged into a plurality of adjacent sheet members. The fingers are disposed between and support adjacent pairs of the sheet members so that each adjacent pair of the sheet members forms a flow channel. A method for filtering gaseous hydrocarbons from an air flow is also provided.

Abstract: A duct assembly comprises a collar that defines a bore and has a first plurality of slots and a second plurality of slots formed therethrough. The collar includes an annular wall formed within the bore and an end groove formed at one end thereof. A duct has an end fitted within the end groove. A ring is disposed within the collar and abuts the annular wall. A ring retainer is disposed within the collar and abuts the ring. The ring retainer has a plurality of tabs formed thereon that fit within the first plurality of slots. An end of a port extends into the collar. The port has an annular groove formed along its circumference. A clip that has a plurality of arcs formed along its length extends around the collar. The arcs extend through the second plurality of slots into the annular groove of the port.

Abstract: A PCV system includes heated PCV valve for metering a flow of crankcase gases therethrough and a heated inlet manifold fitting for receiving a flow of crankcase gases therethrough. The PCV valve and the heated inlet manifold fitting are in communication with a current source to apply current to heaters associated with each as required.

Abstract: An emission control module (14) includes a housing (52) that includes an atmospheric air opening (102) and a vapor emission inlet (104) for communication with a vapor region (32) of a fuel reservoir (16). A hydrocarbon filter (56) is disposed between the atmospheric air opening (102) and the vapor emission inlet (104) to passively filter vapor emissions within the vapor region (32). The housing (52) is configured for purging of the hydrocarbon filter (56) due to a low-pressure draw from the vapor emission inlet (104).

Abstract: A quick connector for establishing a connection between a flexible tube and an interior chamber of a vessel. The vessel has a wall structure through which a mounting bore extends. A canister assembly associated with the quick connector includes a housing is adapted for installation in the mounting bore, a retainer coupled to the housing that adapted to accept and retain a port connector of the hose therein, and a spring clip for coupling the housing to the wall structure. Flanged ends of the spring clip are retained in, and project outwardly from, corresponding apertures formed through a leading end of the housing. Upon installation of the housing into the mounting bore, the end flanges are deflected inwardly until the leading end of the housing extends beyond the mounting bore. Then the flanged ends return to their expanded condition, thereby coupling the canister assembly to the vessel.

Abstract: A connector assembly for conveying fluids, the connector assembly includes a retainer member positioned and locked inside a housing having an axial bore for receiving one end of a male conduit member. A locking arm is flexibly attached to one end of the retainer member to lock the male conduit member into the housing by engaging an annular collar located a given distance from approximal end of said male conduit member thereby providing a fluid tight connection.

Abstract: A PCV valve for use in conjunction with an engine of a motor vehicle that reduces audible noise and increases the efficiency at which blow-by gases are routed to the engine's intake manifold to be re-burned. The PCV valve includes a housing having an inlet and an outlet. A plunger having a first end segment and a second end segment with an intermediate segment therebetween is disposed within the housing. A plunger seat disposed between the inlet and the outlet includes an orifice through which the first end segment of the plunger extends. An inlet plunger guide is disposed in the housing for receiving the second end segment of the plunger and an outlet plunger guide is disposed in the housing for receiving the first end segment of the plunger. Blow-by gases flow between the inlet and the outlet with the plunger moving axially within the housing in response to pressure changes at the outlet to control the flow rate of the gases.
