20090205605 | ENGINE INCLUDING A SELF-ADJUSTING THERMALLY COMPLIANT BRACKET - An engine bracket assembly may include a first mounting portion, a second mounting portion, and a support member. The first mounting portion may fix a first end of the bracket assembly to the engine and the second mounting portion may fix a second end of the bracket assembly to the engine. The support member may support an engine component and may be disposed between and coupled to the first and second mounting portions. The coupling between the first and second mounting portions and the support member may provide relative displacement between the first mounting portion and the support member in a longitudinal direction extending from one of the first and second mounting portions toward the other of the first and second mounting portions during thermal expansion of the bracket assembly. | 08-20-2009 |
20100101528 | ACOUSTIC BUMPERS WITH ENGINE FRONT COVER HIDDEN MOUNTING - The present invention provides novel acoustic bumpers that can dampen vibrations and control noise transmission from an engine front cover, or other component. In one embodiment, the front cover carries a water pump and internal water distribution passages and covers an overhead camshaft drive mechanism and an oil pump mounted on the engine block. Noise control of unsupported cover central portions is provided by acoustic bumpers carried on inside cover bosses and engaging surfaces in accessible locations on the engine block front face or on associated components. The acoustic bumpers may be doughnut shaped annular rings having identical coaxial locating recesses on opposite sides for error-free installation. A central web between the recesses includes an axially located retainer hole. Each bumper may be mounted on a pillar on the inside cover face that includes a fastener receiving blind hole centrally located on a raised circular boss. | 04-29-2010 |
20100101604 | WINDSHIELD WIPER DE-ICING - Methods and apparatus are provided for vehicle windshield washing-wiping and wiper de-icing. Primary nozzles provide washing fluid to the windshield during normal operations and secondary nozzles bathe the wiper arms with washing fluid to de-ice the wipers during a de-icing mode. Washing fluid is drawn from a reservoir and delivered to the nozzles by a pump. When the outside air temperature T is greater than Tc, the critical temperature for ice formation, the wipers and washing-wiping proceed normally with washing fluid delivered to the primary nozzles for windshield washing. When T≦Tc and the wipers are not moving, a washer fluid supply line valve delivers washing fluid to the secondary nozzles to de-ice the wipers. The wiper motor, washing fluid pump and valve are operated by a controller based on inputs from wiper position and air temperature sensors, using predetermined information stored in on-board memory. | 04-29-2010 |
20100122870 | ENGINE WITH OIL PUMP MUFFLER AND NOISE DAMPER - A wrap-around cover or noise muffler of oil and temperature resistant noise absorbing resilient elastomer covers the front and sides of a front mounted engine oil pump forming a pump and muffler assembly. The muffler absorbs vibrations and reduces the transfer of noise frequencies from the oil pump to an engine front cover that covers the pump. Additionally, the front of the muffler is shaped to fill the gap and engage the front cover in compression between the oil pump and the rear surface of the front cover, thereby damping vibrations of the front cover adjacent to the oil pump and to an accessory drive pulley that rotates ahead of the front cover for driving accessories. | 05-20-2010 |
20120014746 | GASKET-END FEATURE FOR SEALING A T-JOINT ASSEMBLY - A t-joint assembly includes a gasket having first and second ends, and a substantially elongated body having a profile. The first end includes an enlarged tapered section having a distal tip and a force-transfer surface disposed substantially perpendicular to the body. The assembly also includes a first component having a channel with a profile and a reaction surface configured to respectively complement the profile and accept the force-transfer surface of the gasket. The first component also has a first sealing surface arranged substantially parallel to the reaction surface, and a second sealing surface arranged substantially perpendicular to the reaction surface. The t-joint assembly additionally includes second and third components, each having a sealing surface. Inserting the gasket into the channel and assembling the three components compresses the gasket against the channel, and the tip of the gasket against the reaction surface, to thereby seal the t-joint. | 01-19-2012 |
20120180753 | ACTIVE THERMAL SHIELD AND DIVERTER - A thermal shield-diverter includes a first layer and a second layer. Each of the first and second layers is formed from a material resistant to thermal energy, and each is characterized by a surface having a width and a height. The shield-diverter also includes a third layer formed from a material substantially non-conductive of thermal energy. The third layer is characterized by a third width and a third height, and is disposed between the first layer and the second layer to define at least one passage extending along at least one of the first height and the second height. The at least one passage is configured to divert thermal energy along the respective first and second heights and expel the thermal energy from the shield-diverter when the shield-diverter is exposed to a heat source. An engine assembly employing such a shield-diverter is also disclosed. | 07-19-2012 |
20120181756 | ANNULAR SEAL WITH TRAPEZOIDAL CROSS-SECTION - An annular seal for sealing between a cylindrical probe and a bore includes a radially inward-facing sealing portion having a first contact height, a radially outward-facing sealing portion having a second contact height, where the first contact height is greater than the second contact height. The seal further includes a vertical-loading portion, and a sloped deformation portion that extends between the vertical-loading portion and the radially outward-facing sealing portion. | 07-19-2012 |
20140232498 | INTEGRATED INTERLOCK FEATURE FOR OVERMOLDED COIL AND BOBBIN - An electromagnetic solenoid is provided with a bobbin having a generally cylindrical body and a pair of radially outwardly extending end flanges each disposed at opposite ends of the generally cylindrical body. The pair of end flanges each have an inner face facing one another and an outer face facing away from one another. The inner and outer faces of the pair of end flanges have a plurality of grooves formed in a surface thereof. The grooves provide for enhanced retention of an over-mold that seals a coil within the bobbin assembly. | 08-21-2014 |
