摘要： 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 a grove formed in the plunger. The stopper is bent so that its handle extends away form the pin axis at an angle greater than zero but not greater than 90°. Removal of the stopper from the tensioner can be carried out by rotating the handle to avoid interference with engine components in the vicinity of the tensioner.

摘要： In a ratchet-type tensioner, a rocking ratchet pawl is released from a rack of teeth on a tensioner plunger following engine start-up by a hydraulically operated pin slidable in a pin hole and caused to protrude therefrom by oil under pressure received directly from an external oil supply, or alternatively from the tensioner's high pressure oil chamber through a passage in the tensioner housing. Optionally, an orifice can be provided within the pin hole to control flow of oil when the supply is excessive and to avoid leakage when the supply is insufficient.

摘要： In a ratchet tensioner, a linearly moving ratchet for engagement with rack teeth on a plunger is operated a piston that is spring-biased in a direction to engage the ratchet teeth with the rack, and movable by oil pressure in a direction to disengage the ratchet teeth from the rack. The piston is located within a hole in the housing and, with that hole, forms a second high pressure oil chamber that can receive oil through an oil supply path independent of the oil supply path that carries oil to a first high pressure oil chamber formed by the plunger and the tensioner housing.
