Abstract: A quick connector body includes a bore fluidically coupled to a bore extending from an open end of an endform when the body is mounted on the endform. Cooperating, initially spaced, latch members and latch engagement members are unitarily carried on the connector body. A collapsible portion is formed on the body between the latch members and the latch engagement members for radial inward protrusion into an annular groove in the endform substantially concurrent with engagement of the latch members and the latch engagement members to fixedly couple the connector on the endform. In one aspect a second end of the connector body is closed to form the connector body as a test cap. In another aspect, a second end of the connector body is open to establish a fluid flow path from the endform to a fluid component coupled to the second end of the connector body.

Abstract: A method for preparing a multi-layer tube, useful prior to endforming for brakeline connections, comprises the steps of forming a metal tube having an outer surface and an end and bonding a corrosion resistant layer to the metal tube outer surface. A surface treatment layer is bonded to the corrosion resistant layer. A first polymeric layer is extruded onto the metal tube, such that is bonds to the surface treatment layer; and a second polymeric layer is extruded onto the metal tube, such that it bonds to the first polymeric layer. The method further comprises the step of vaporizing and removing at least a portion of the first and second polymeric layers from an area adjacent the end by rotating an axially defocused, generally elliptical cross-sectionally shaped laser beam 360° about the area, while leaving the corrosion resistant layer intact.

Abstract: An apparatus retains and aligns an electrical ignition switch of a motor vehicle with respect to a steering column housing. A switch housing supports the electrical switch and has at least one first aperture formed therein. The steering column housing slidably receives the switch housing therein, and the steering column housing has at least one second aperture formed therein. At least one locking member is engagable within the first aperture and is moveable between a first position retracted within the aperture and a second position extended outwardly with respect to the first aperture. The locking member engages within the second aperture when the switch housing is slidably engaged and fully seated within the steering column housing and holds the switch housing with respect to the steering column housing when engaged within the second aperture. A biasing member urges the locking member toward the second position.

Abstract: A quick connector releasibly connects first and second conduits fixedly mounted in first and second, interconnectable connector bodies. The first body has an axially extending tubular first end, a frusto-conical portion, a reduced diameter shaft and an enlarged second end. A pair of angularly inwardly extending latch arms project from the second body to releasibly engage a peripheral edge on the frusto-conical portion of the first body.

Abstract: A traction control system for a four wheel drive vehicle including generating a first value corresponding to an average rotational speed of front wheels, generating a second value corresponding to an average of a rotational speed of rear wheels, comparing the first and second values, and generating a first signal corresponding to a difference between the first and second values, are provided. The first signal is used for transferring torque to the secondary axle if the rear wheels are rotating faster than the front wheels. The system also generates a second signal corresponding to a difference in speed between a first axle shaft and a second axle shaft of the front axle. The second signal is used for transferring torque to the other of the front axle shafts if the one of the secondary axle shafts is rotating faster than the other of the front axle shafts.

Abstract: An end fitting closes at least one end of a passageway having an external periphery and an internal periphery to be cast-in-place within a part. A fitting body has at least one elongated, blind-ended aperture formed therein. The aperture is defined at least in part by a first surface having a complimentary shape with respect to the external periphery of the cast-in-place passageway for receiving an end of the passageway disposed extending at least partially therein to close the passageway during casting of the part. The fitting body is composed of material essentially identical to material being used during casting of the part. The fitting body is positionable within a casting mold for forming the part to be cast, such that machining the cast part after casting opens the blind-end of the fitting to allow fluid flow through the passageway cast-in-place within the part.

Abstract: A quick connector formed of a housing having an internal bore receiving one end of a male connector with a radially enlarged annular flange. A retainer carried on the housing has a cylindrical sleeve disposed in the stepped bore in the housing. Pivotal tabs extend from the sleeve to fingers extending angularly inward into the bore to engage the annular flange and prevent axial disengagement of the male connector from the housing. Release members extend from each tab and are adapted for pivotal, radially outward movement causing like radially outward movement of the fingers to disengage the fingers from the annular flange and to allow separation of the male connector from the housing. Lock surfaces carried on the housing engage the release members during radially inward movement of the release members caused by an axial load on the male connector to resist axial separation of the housing and male connectors.

Abstract: A fluid conduit quick connector includes first and second releasably connectable bodies. A tapered bore in the first body receives one end of a first conduit. A tubular extension projecting from one end of the second body is coaxially received in the conduit when the first and second bodies are releasably joined together. The conduit is sealingly compressed between the tapered bore and one or more projections on the extension. A third body carries another conduit and is releasibly connected to the second body. The third body also includes mounting members to fixedly mount the third body to a support.

Abstract: A quick connect coupling for high pressure fluid includes a male fitting body connected on the end of an elongated tube. The male fitting body has an annular recess for receiving a retainer movable between a compressed position allowing longitudinal insertion of the male fitting body within a corresponding female aperture and a released position for retaining the male fitting body seated within the female aperture. A visual indication is provided to signal if the retainer is fully seated within a corresponding groove of the female aperture. A locking member maintains the retainer in the released position in response to seating the male fitting body within the corresponding female aperture. A biasing member urges the male fitting body in an opposite direction with respect to the longitudinal insertion direction within the corresponding female aperture.

Abstract: A quick connect coupling including a female connector member adapted for quick connect engagement with a male connector member. The male connector member has an annular bead defined by leading and trailing annular edges. The female connector member defines an axial bore sized to slidably receive a leading end of the male member defined forwardly of the leading annular edge of the bead and a plurality of circumferentially spaced resilient fingers adapted to snap into position behind the bead and into engagement with the trailing annular edge of the bead as the leading end of the male member moves into the bore and the leading annular edge of the bead moves into engagement with a radial seating surface defined around the entrance to the bore.

Abstract: A key cylinder, upon receiving a valid key, inserted through the key cylinder, is disengaged from a cylinder lock enabling the key and the key cylinder to be rotated between two positions. During rotation, an arm on the key cylinder engages a contact carrier to switch a contactor mounted on the carrier between two positions breaking one contact and subsequently making another contact. The contacts provide output signals to a vehicle passenger restraint apparatus to selectively alternatively place the passenger restraint apparatus in an "on" or "off" state.

Abstract: A retainer for releasably locking the male and female components of a quick connector. The retainer is releasably insertible into a transverse bore in the female component and is blocked from full insertion by a projection. An extension projects from the retainer and has an aperture sized to receive the tip end of the male component, but not a radial flange on the male component when the retainer is partially inserted into the female component. Forced insertion of the male component breaks off a ring portion of the extension thereby enabling the radial flange on the male component to fully move into the female component. The retainer can then be urged into the fully latched position locking the male and female components.

Abstract: A disc brake for a motor vehicle includes a rotor mounted to a wheel and rotatable about a first axis therewith; a pair of parallel-spaced pins removably mounted to the vehicle chassis so as to extend in a direction generally parallel to the first axis; a pair of brake shoes having slots for receiving the pins on either side of the rotor so as to place brake linings respectively mounted on the pins in opposition with complementary annular friction surfaces on either side of the rotor; and a caliper slidably supported by the two pins so as to straddle the rotor and both brake shoes, respectively. The slots of the brake shoes are defined in part by a finger configured to deflect responsive to a brake load and the deflection of the finger enables the sequential engagement of the brake shoes against the pins.

Abstract: An accumulator for an anti-lock brake system includes a valve body portion defining an accumulator chamber, an accumulator piston slidably disposed within the accumulator chamber, a spring, and a cover. The accumulator chamber has a fluid inlet for connection to a source of pressurized fluid at a first end of the chamber. The chamber has a second end open to atmosphere. The accumulator piston separates the first end of the chamber from the second end of the chamber. The spring is disposed in the accumulator chamber between the piston and the second end of the chamber and biases the piston toward a first position. The cover closes the second end of the chamber and atmosphere and has micro-porous structure. The micro-porous structure is configured to block water molecules and to pass constituent molecules of air, thereby enabling air to be communicated across while preventing the intrusion of water into the chamber through the second end.

Abstract: A reservoir for a master cylinder including an upper reservoir section forming a portion of a float damping chamber and a lower reservoir section forming a portion of the float damping chamber. The upper reservoir section and the lower reservoir section are so dimensioned so that when they are fastened together, they define the float damping chamber at least one metering orifice formed along their mating surfaces. This metering orifice allows fluid to flow between the float damping chamber and the reservoir of the master cylinder in a controlled manner. Thus, a float device provided within the float damping chamber will not be susceptible to initiating false signals.

Abstract: A modular pin mounted caliper assembly is provided for use in a disc brake. The modular caliper assembly can be angled with one or more other modular caliper assemblies. Each caliper segment has a housing with a piston disposed in an inboard portion thereof for movement in an axial direction. A pair of flanges extend from opposite sides of the housing and are axially offset from each other enabling the connection and alignment of a plurality of segments. The resulting caliper can be used in a wide variety of vehicles despite changes in brake torque requirements. The modular caliper assembly includes a plurality of inboard and outboard brake shoe pairs. Each brake shoe has a pair of pin engaging features extending from opposite outboard ends of the brake shoe. Like the caliper segment flanges, the pin engaging features are axially offset from one another, enabling the shoes to be overlapped on common pins.
