Abstract: A quick connector coupling comprising a hollow female connector body, a male member having an enlarged annular upset received in the connector body, and a retainer releasably securing the male member in the connector body. A two piece insertion verifier assembly has a clip and a pull member connected together. The clip is attached to the connector body. The clip further includes a flexible cross member joining the two legs. The cross member includes an asymmetric tab, offset from its center toward one of the legs. The body has a protrusion on an outer surface. The tab and the protrusion insure proper orientation of the clip relative to the connector body and tube. With the upset secured by the retainer, it contacts the two legs of the clip to deform the legs apart to permit the clip to disengage from the connector body. However, the pull member and clip separate if a pulling force is exerted on the pull member with the male member not fully inserted into the connector body.

Abstract: A quick connector coupling assembly to connect a rigid tube to a hollow body component. A retainer releasably retains the tube within a bore in the body. A resilient seal member surrounds the tube and creates a fluid tight seal against the tube and the body defining the bore. A seal member retainer interposed between the seal member and the body transfers axial load on the seal due to pressure to the body. In one embodiment a polyfluoroethelene spacer is interposed between the seal member and the seal member retainer.

Abstract: A quick connector coupling comprising a connector body, a tubular male member with an upset, a primary retainer and a separate redundant latch/verifier. The connector body defines a through bore and the male member extends into the bore. The primary retainer releasably secures the male member within the connector body. The redundant latch/verifier is releasably coupled to the connector body and movable between an unlatched position and a latched position. It includes spaced apart fingers with verifying tabs that permit movement to the latched position only after full insertion of the male member. The fingers have release tabs to manually spread the extension beams. In another form, the connector body includes locking pads extending radially inward. The legs of the primary retainer are located inward of the locking pads preventing the legs from moving to a released position if said male member is pulled in a direction to remove it from the connector body.

The outer cylindrical surface of the tube is press fit into the reduced diameter bore at the tube receiving end to connect the coupling to the tube. The coupling body is crimped to the tube and to the hose to secure the hose and tube to the coupling. The tube is axially restrained between the crimp and an annular wall in contact with the tube end. In another embodiment, a second seal, outward of the upset is employed to prevent entry of contaminants.

Abstract: A method of relieving hot soak pressure in a fuel rail of a fuel injected internal combustion engine includes pressurizing fuel with a fuel pump when the engine is operating, and conveying the pressurized fuel through a check valve that prevents backflow of fuel from the fuel rail toward the fuel pump. A bypass path is in fluid communication between a location downstream of the check valve and a location downstream of the fuel pump and upstream of the check valve. The bypass path is opened when the engine is not operating so as to relieve fuel pressure downstream of the check valve to a level below a system operating pressure. Apparatuses are provided for carrying out the method.
