The rail has a fluid passageway defined therein, the fluid passageway being in fluid communication with the source of fluid. A connector is in fluid communication with both the rail and with the fuel injector for fluidly connecting the rail to the fuel injector. The connector is universally moveable in three axes for accommodating static tolerances existing between the rail and the fuel injector and for accommodating dynamic relative motion between the rail and the fuel injector such that stresses imposed on the fuel injector resulting from being attached to the rail are substantially eliminated.

Abstract: The present invention describes a filter screen for removing debris from the hydraulic actuating fluid in an internal combustion engine having a hydraulic pump for supplying hydraulic actuating fluid to hydraulically-actuated unit fuel injectors. An upper portion of a priming reservoir is mounted on a front cover of the engine. The front cover forms a lower reservoir portion. A screen assembly is positioned adjacent to an interface defining an entrance from the upper reservoir portion to the lower reservoir portion. The screen assembly includes a filter screen enclosing the entrance to force the actuating fluid to pass through the filter screen, thus retaining debris that exceed the mesh size of the filter screen.

Abstract: A suspension system for a vehicle frame from a steering axle has first and second controllable rate springs mounted above the steering axle and below the frame to support a portion of vehicle weight. A trailing V-link member is mounted to pivot on its vertex on a cross-member of the frame forward of the steering axle. The opposite ends of the V-link member are pivotally connected to opposing ends of the steering axle allowing the V-link member to constrain fore to aft movement of the steering axle, lateral displacement of the steering axle and frame roll. A pitman and trailing draglink from a steering gear on the frame to the steering axle controls steering. First and second shackle assemblies depend from the frame aft of the steering axle. First and second leading arms are suspended from the shackle assemblies to permit longitudinal translation of the first and second leading arms relative to the frame.

Abstract: A backshell for an electrical connector gives the electrical connector handedness to force a particular orientation of the connector with respect to a device in order to limit the choice of devices to which the electrical connector can be attached. The backshell fits around the connector and a portion of a cable connected to the connector. The cable is forced into a right angle turn in the interior of the backshell to give the device handedness.

Abstract: A stowable partition assembly for a truck cab provides privacy for an interior sleeping area mounted aft of the operator space. The assembly has an overhead track depending from the cab ceiling, oriented to define a border between the forward operator area and the aft interior sleeping area. A pair of curtains are hung from their upper edges from the overhead track and are positionable on the track to divide the aft living space from the forward operator space when extended. A pair of stowage compartments are located at each end of the track along the interior sides of the truck cab to receive the curtain when retracted. Retraction of the curtains is provided by roll up retractors disposed in each stowage compartment. The curtains are each attached along one of two vertical edges to the roll up retractor to be wound thereon. An interlocking latch provides closure of the curtains when pulled from the stowage compartments.

Abstract: A communication system architecture (SA) for a vehicle which may be integrated into the vehicle's multiplexed electronic component communication system, and a process for communicating with the vehicle to provide information for and about the vehicle's operational status and coordinating the vehicle's activities. The communication system will include a multi-functional antenna system for the vehicle that will have the capability to receive AM/FM radio and television signals, and transmit and receive citizens band (CB) radio signals, satellite and microwave and cellular phone communications. The antenna may be installed as original equipment or as a back-fit part in the after-market. In either case the multi-functional antenna will be integrated with the vehicle's multiplexed electronic component communication system.

Abstract: The invention provides a cranking inhibition control system for an electric starter to an internal combustion engine. Engine rotational speed is developed from the signal produced by a cam shaft position sensor, which drives the logic of the system. Responsive to changes in engine rotation speed which result in engine speed falling below idle speed, the control logic generates a temporary cranking inhibit signal. Once engine speed falls low enough to clearly indicate cranking has ceased, a timer is triggered which resets the inhibit signal to permit cranking after a suitable delay.

Abstract: The invention provides a single member insert positionable between a front axle and each front leaf spring as a spacer. The member allows attachment of one end of a shock absorber for bracing against the axle. The member also serves as a caster wedge for maintaining proper steering response.

Abstract: A mounting arrangement for a modular component such as a fuel tank for a vehicle such as a truck and a method of installing same on the vehicle. The method is accomplished via a combination of a set or sets of two brackets and an initial alignment means for each set of brackets. The initial alignment means is comprised of two mating components, with one mating component being a portion of one bracket and the other mating component being a portion of the second bracket. One bracket of each set is installed directly to a portion of the vehicle under manufacture, such as to the frame rail. A modular assembly is assembled separately with the second bracket of each set installed on the modular assembly. The sets of brackets are joined via the initial alignment means attaching the modular assembly to the vehicle.

Abstract: A hydraulically-assisted engine valve actuator and method for assisting in the actuation of an engine valve includes a translatable pilot valve that is operably coupled to and controlled by a pilot valve positioning system. A servo piston is in fluid communication with the pilot valve and is operably coupled to the engine valve. The pilot valve positioning system controls translation of the pilot valve to meter hydraulic fluid under pressure to and from the servo piston. The hydraulic fluid under pressure causes the servo piston to closely follow the translation of the pilot valve to effect a desired profile of translational opening and closing motion of the engine valve.

Abstract: A push-to-connect tubing fitting which has a body, a collett with tubing gripping teeth that engage the tubing, and sealing devices. The collett is disposed within a bore in the body of the fitting. The collett has tubing gripping teeth on its inner bore which mechanically engage the outer surface of the tubing. A first sealing device is positioned within an inner bore of the collett at a point closer to the tubing insertion opening of the collett than are the tubing gripping teeth. This first sealing device seals the tubing to the collett. A second sealing device is disposed between the collett and the body. This second sealing device seals the collett to the body of the fitting and effectively completes the seal between the tubing and the body.

Abstract: An occupant compartment of an automotive vehicle contains an instrument panel to the rear of which an occupant of the vehicle may be seated. A knee bolster is disposed below the instrument panel frontally of the occupant's knees and has a through-opening toward the occupant. A movable cover selectively closes and opens the through-opening. When the cover is closed, it covers a key that was inserted into the vehicle ignition switch and turned to operate the switch to turn on the engine while the cover was open. The ignition switch is disposed in a mounting that extends outward when the cover is opened to render the switch accessible for key insertion, key operation, and key removal. When the cover is closed, the mounting and switch retract within the knee bolster.

Abstract: The invention relates to a method of vehicle collision severity discrimination for actuating a safety device at an occupant location in the vehicle. The method provides steps for providing a plurality of velocity and load level trigger values, including velocity and load level pairs, indicating a plurality of threshold conditions for actuating the safety device at an occupant location. Vehicle velocity and load are monitored so that at the instant of a collision a severity evaluation may be made, particularly where the potential for vehicle crush ameliorates the potential danger to the occupants. Responsive to selected vehicle conditions, a collision indication signal is generated Responsive to generation of a collision indication signal, vehicle velocity, vehicle load, or both, are compared to threshold conditions for actuation of the safety device.

Abstract: A tubing coupler for mechanically and fluidly connecting two pieces of tubing. The tubing coupler has a first body portion with a pilot and a second body portion with a cavity in which the pilot is disposed when the tubing coupler is assembled. A fluid passageway through the first body portion and the pilot of the first body portion is in fluid communication with a fluid passageway through the second body portion and the cavity of the second body portion. Thus fluid flow is allowed through the coupler. A primary sealing device circumscribes the pilot of the first body portion and seals the space between the pilot of the first body portion and the cavity of the second body portion. A plate is disposed between the first body portion and the second body portion and defines an opening through itself through which the pilot of the first body portion protrudes. A secondary sealing device is disposed inside the periphery of the opening in the plate and surrounds a portion of the pilot.

Abstract: A system and a method for detecting compromised vehicle wheel and tire operating characteristics includes detection for out of round new tires, under pressure tires, poor front wheel alignment and off center line loads. The instantaneous rotational velocity signal generated for each wheel by an existing antilock braking system (ABS) provides data for the basic comparison of wheel speed is against an instantaneous indication of vehicle speed. Once calibrated, the system provides operational monitoring of the wheels includes initializing the trip odometer, collecting wheel speeds, and sampling vehicle speed. Tire radius and tolerance data as a function of estimated wear and tire temperature. Tire temperature is in turn a function of ambient temperature and trip distance. The rotational velocities for the wheels are estimated as functions of vehicle speed and the updated tire radius data.
