The piston spring ... 12/21/06 - 20060287146 - Belt alternator starter accessory drive with dual tensioner An accessory drive for an engine has a belt driven starter generator adapted for driving and being driven by the engine. In an exemplary embodiment, the drive includes a first engine drive pulley and a second starter drive pulley. A drive belt engages the drive pulleys for driving either pulley ... 12/14/06 - 20060281595 - Tensioner A tensioner that includes a piston supported slidably in a piston bore formed in a housing, a piston spring biasing the piston in the protruding direction, and a circlip member having an expandable ring-shaped body that is engageable with the rack teeth of the piston. In the piston bore, the ... 12/14/06 - 20060281594 - Mechanical chain tensioner with a rotational ratcheting device A blade tensioner comprising a blade shoe with a proximal end pivotally attached to the bracket and a distal end of a clevis shape having a raised portion and a recessed portion for receiving a semicircular ratchet wheel, with an edge of the raised portion defined by a radial journal ... 11/30/06 - 20060270500 - Chain tensioner This invention provides a chain tensioner that is compact, excellent in operation, easy to maintain and handle and low in manufacturing cost. This chain tensioner has a tubular housing 1 having a bottom, a plunger 3 installed in the inner periphery 1a of the housing so as to smoothly slide ... 07/20/06 - 20060160645 - Tensioner with ratcheting device A tensioner including a housing having a bore, a hollow piston, a piston spring, a check valve between the source of pressurized fluid and hollow piston, and a pawl plate. The hollow piston is slidably received within the bore of the housing and forms a fluid chamber with the bore. ... 07/13/06 - 20060154764 - Ram-type tensioner assembly having integral hydraulic fluid accumulator The invention is directed to a tensioner assembly for providing tensile force from a floating vessel at the surface of the ocean to the blowout preventer stack, or production tree, which is connected to the wellhead at the sea floor. The tensioner assembly compensates for vessel motion induced by wave ... 05/11/06 - 20060100047 - Compliant snubber A compliant snubber for a chain is disclosed. The snubber preferably includes an elastomeric body and metal bushings. The compliance feature allows the snubber to be located with a negative clearance to the back side of the chain without causing excessive surface loads that may result in excessive snubber surface ... 05/04/06 - 20060094548 - Chain tensioner A chain tensioner includes a housing defining a cylinder chamber, and a plunger having a small-diameter end and a spring both mounted in the cylinder chamber. A register ring is fitted in a ring-receiving groove formed in the inner periphery of the cylinder chamber near its open end. A plurality ... 04/27/06 - 20060089220 - Chain tensioner A mechanical anti-backdrive chain tensioner includes a four-sided planar piston and plastic chain shoe assembly. A pair of helical compression springs of opposite helices urges the piston and shoe assembly into the chain, and a ratchet plate pawl prevents backdrive of the piston but is designed with a predetermined amount ... 04/20/06 - 20060084537 - Tensioner with improved stopper In a tensioner for a timing chain, a spring-biased plunger for urging a shoe into sliding engagement with the chain is temporarily held in a retracted condition, prior to installation of the tensioner, by a stopper having a pin that extends through a hole in the tensioner housing and engages ... 04/13/06 - 20060079359 - Tensioner with drainhole A belt tensioner is provided for mounting on a mounting surface of a structure. The tensioner comprises a body, which defines a cavity, and a drain hole that is in communication with the cavity. The drain hole is located on the body so as to be facing the mounting surface ... 03/09/06 - 20060052194 - Torsional force linear tensioner A linear tensioner driven by a torque input is provided having a base, a pinion rotatably mounted on the base, a rack operatively engaged with the pinion, an arm slideably mounted on the base and coupled to the rack for linear movement therewith, and a pulley rotatably mounted on the ... 03/09/06 - 20060052193 - Pivot assembly A pivot assembly to permit relative pivotal motion of a sleeve of the pivot assembly about a pivot axis. The pivot assembly may contain a spherical bearing assembly therein. The spherical bearing assembly may include a spherical portion and a tubular portion, wherein the tubular portion is operable to form ... 11/10/05 - 20050250609 - Thin autotensioner An autotensioner comprises a torsion coil spring interposed between a base and a rocking arm, and a tubular bushing provided between an inside surface of the base and an outside surface of the rocking arm.
