摘要： High-offset belt tensioners have a support base with a pivot tube and an arm coupled thereto rotation about a pivot axis. A flat wire torsion spring has an inner spring hook attached to the pivot tube and an outer spring hook attached to a first end of the arm at a position that counterbalances a hub load force. The torsion spring applies a spring force to the arm in a direction that moves with the arm throughout its entire sweep in a belt engaging direction. A first plane of the hub load force is axially offset from a second plane of the spring force, a fulcrum is defined between first and second ends of the arm, and a first lineal axial distance from the fulcrum to the first plane is greater than or equal to a second lineal axial distance from the fulcrum to the second plane.

摘要： Check valves have a housing defining an internal cavity and a first port and a second port both in fluid communication with the internal cavity and have a hemispherical poppet sealing member within the internal cavity and translatable between a closed position against an annular seat within the internal cavity of the housing and an open position. The annular seat, in a longitudinal cross-section through the check valve, defines a convex spherical radius and, in the closed position, a convex surface of the hemispherical poppet sealing member is sealing engaged with the convex spherical radius of the annular seat.

摘要： Torsional vibration dampers for rotating shafts are disclosed that have a hub or a hub portion of a pulley-hub monolithic body that has an innermost sleeve defining a bore, an outermost ring concentric with and spaced radially outward from the innermost sleeve, and a plurality of spokes connecting the innermost sleeve to the outermost ring that each have torsional flexibility to act as a first spring to attenuate torsional vibrations. The dampers include an elastomeric member positioned concentrically against the outermost ring or the innermost sleeve of the hub, where the elastomeric member acts as a second spring to attenuate torsional vibrations, and an inertia member positioned concentrically against the elastomeric member, which places the first spring and second spring in series. The dampers may be crankshaft, driveline, or direct drive dampers, and the equivalent spring rate for the first and second springs is governed by the elastomeric member.

摘要： Venturi devices and systems incorporating the Venturi devices are disclosed. The Venturi devices have a body defining a passageway that has a motive section and a discharge section spaced a distance apart from one another to define a Venturi gap. Both the motive section and the discharge section converge toward the Venturi gap. Also, the body defines a first suction port and a second suction port generally opposite one another that are each in fluid communication with the Venturi gap. The Venturi gap is generally wider proximate both the first suction port and the second suction port than at a generally central point therebetween. In a system, the Venturi device has its motive section fluidly connected to a source of motive pressure and one or both of the first and second suction ports in fluid communication with a device requiring vacuum.

摘要： Torsional vibration dampers having isolator members (crankshaft damper-isolators) are disclosed that include a hub defining an annular receptacle, a pulley body having a belt engaging surface, a damper assembly disposed between an outermost radial surface of the hub and the pulley body, an isolator member seated in the annular receptacle of the hub, and a slide bearing disposed between an outer radial surface of the hub and the sleeve of the pulley body. The isolator member is engaged with both the hub and the pulley body for rotation therewith when the hub and pulley body rotate at the same speed and when the hub rotates relative to the pulley body. The isolator member may be an elastomeric isolator or a torsion spring isolator. The slide bearing axially retains the pulley body to the hub and allows the pulley body to rotate relative to the hub.

The tensioner has an arm that is rotatable about a first axis. The tensioner also includes an outer spring and at least one inner spring. The outer spring has an outer coil that defines an outer diameter. The inner spring has an inner coil that defines an inner diameter. The inner diameter of the inner coil is less than the outer diameter of the outer coil such that at least a portion of the inner spring is received by the outer spring. The outer spring and the inner spring both urge the arm to rotate about the first axis and into tensioning engagement with the power transmitting element.
