Abstract: A device and method for roller swaging a tube and a fitting using a tapered mandrel acting on forming rollers and having a rack body that supports lead screws that are rotated by a rack motor where the lead screws are used to move the rack drive head and the axial position of the mandrel. The mandrel is supported by a roller bearing having roller elements that are parallel to the rotational axis of the mandrel. A position sensor is attached between the rack body and the rack drive head to indirectly measure the position of the mandrel and/or a position sensor can be used to directly measure the position of the mandrel. The drive motor drives a primary drive shaft through a torque sensor to a secondary drive shaft to a roller swaging assembly and to the mandrel. The swage rollers in the roller swaging assembly are forced outward by the tapered mandrel to swage the tube and fitting.

Abstract: A valve is disposed between a fuel tank and an engine intake manifold in a small engine fuel system equipped to recapture running loss evaporative emissions. The valve includes a resilient diaphragm that blocks the flow path When vapor pressure in the fuel tank reaches a predetermined level, the diaphragm opens and allows the vacuum forces in the manifold to purge the vapors in the fuel tank by drawing the vapors into the manifold to be burned in the engine. The diaphragm isolates the fuel tank vapor dome from the vacuum pressure generated in the manifold, thereby preventing the engine from being starved of fuel. The valve may be integrated with a liquid discriminating valve to form a valve assembly.

Abstract: A valve is provided. The valve may include a housing defining a cavity. A first end of the housing may define an opening configured to be closed by a flapper door. The valve may further include a hinge formed integrally with the housing. The hinge may extend from an upper portion of the housing and be configured to receive the flapper door. In an embodiment, at least a portion of the hinge extends beyond the opening. The hinge may provide a pivot point for the flapper door that is at or above the opening of the housing.

Abstract: A capless filler neck creates a vapor-tight closure for a fuel system using a spring-loaded door and a latch structure that anchors the door to create a vapor-tight seal. The filler neck includes a spring that biases the door shut and a wedge arrangement that acts as the latching structure. The wedge arrangement includes a movable plate that selectively engages with the door to pull the door shut with sufficient force to form and maintain the vapor-tight seal.

Abstract: A float assembly for a multifunction fuel vapor vent valve with a float having a recess formed in the upper surface of the float with a slot formed in the side of the float and communicating with the recess. A raised surface portion is formed in the bottom of the recess and downwardly extending projections are formed in the slot at the recess. A flexible wafer like valve disk is inserted in the slot and deformed or curled to pass under the projections and over the raised surface and into the recess. When fully received in the recess the disk returns to its flat configuration; and, the downward projections prevent removal without distortion. Radially inwardly projections about the recess retain the disk for limited lost motion in the direction of float movement.

Abstract: A float operated fuel vapor vent valve has body structure with an annular mounting flange formed of material weldable to a fuel tank and the flange is spin welded to the tank. The float has surfaces thereon which slidably engage corresponding surfaces in the float chamber to prevent relative rotation of the float with respect to the valve body during spin welding. An optional pressure relief valve in the vent outlet also has surfaces slidably engaging the vent passage to prevent relative rotation during spin welding.

Abstract: Isolation valves of the invention are advantageously mechanically actuated. Such valves and associated methods comprise a first port in fluid communication with a first component; a second port in fluid communication with a second component; a third port in fluid communication with a third component; a diaphragm disposed within the valve for closing a normally open internal pathway to occlude fluid communication between the first port and the second port in response to a pressure differential across the diaphragm; and a flow sensitive pressure device for controlling the pressure differential across the diaphragm. Fluid flows from the second component to the third component upon closing of the normally open internal pathway. In an exemplary embodiment, isolation valves and methods of the invention are adapted for use in fuel tank emission control systems.

Abstract: A plastic bodied fuel vapor management valve has mounting lugs thereon which are adjustably snap-locked onto a bracket provided on a cover for the tank access opening to selectively locate the valve vertically on the bracket. As the valve is engaged with the bracket, a vapor vent fitting provided on the cover is received in the valve outlet and sealed by a seal ring. The cover preferably comprises a mounting flange for a fuel level signal sender.

Abstract: A fuel tank has a recess formed on the inner surface of the upper wall. A vent valve has a mounting portion extending therefrom with a resiliently deflectable disc formed thereon and a guide disc spaced from the deflectable disc. Upon insertion into the recess the deflectable disc is deflected and the periphery thereof frictionally engages the inner surface of the tank wall recess. The guide member slidably fits into the recess to prevent lateral movement of the mounting portion and removal from the recess.

Abstract: Apparatus and method of assembling an interior fuel systems component suitable for immersion in liquid fuel in a tank to an exterior component of different material weldable to the fuel tank. The exterior component is preferably formed of HDPE having a hardness in the range of about RR-40 to RR-80 and has an array of projections extending therefrom. The interior component has a corresponding array of radially extending slots having barbed edges for push on connection to the projections. The slots permit sliding movement due to material swelling of the projection on the barbs without loosening of the connection. The internal component is preferably formed of material comprising a member of the group consisting of Polyamide, Polyketone and Polyphenylamide and having a hardness in the range of about R112, such that the barbs deform the lugs to maintain the connection.

Abstract: A diagnostic testing system for use with two or more lighting systems of the High Intensity Discharge (HID) sports lighting type, wherein two or more lighting systems have their ballasts and diagnostic receptacles combined in a single ballast box at the base of a light pole for diagnostic access. Each lighting system has its own diagnostic receptacle electrically coupled to the other lighting system through a common block supplying power to the multi-system fixture. Each lighting system typically comprises at least one lamp, a ballast, a capacitor, and wiring interconnecting the lamp, ballast, and capacitor. Each diagnostic receptacle includes a continuity plug wired to maintain electrical connection to the common block while it is plugged in, and to cause its associated lighting system to be electrically isolated from the common block when the plug is removed.

Abstract: A combination fuel tank rollover valve, float actuated fill vent shutoff and tank vapor pressure relief valve assembly in a common housing for assembly into a single access opening in the tank. A header containing the pressure relief valve is sealed over the tank access opening and has an extension member attached to the undersurface of the header with an extension neck extending through the access opening. An interchangeable vent float valve subassembly is attached to the end of the neck before attachment of the extension to the header and assembly on the tank. Tanks of different depth can be accommodated simply by using extension members having a correspondingly different length necks, while the float valve subassembly and header are interchangeable.
