Alternatively if an oblique camming surface is formed on the toothed end of the piston, the ratchet teeth can be disengaged from the rack teeth by pushing the tool inward against the oblique camming surface. The piston and the hole in which it slides are shaped to prevent rotation of the piston. The ratchet teeth on the piston and the rack teeth on the plunger can be oblique to allow setback of the plunger when excessive force is exerted on the plunger.11-21-2013
20130324337HYDRAULIC TENSIONER - In a hydraulic tensioner for maintaining tension in a traveling transmission medium in an engine, oil is delivered to an expansible chamber formed by a tensioner housing and a plunger through a reserve chamber composed of an entrance reserve chamber into which oil flows from an oil supply and a supply reserve chamber from which oil flows to the expansible chamber. A partition between the entrance and supply reserve chambers establishes a communication passage that ensures an amount of oil in the supply reserve chamber sufficient to make up the loss of oil due to leakage from the expansible chamber during a long interval while engine is inoperative, and additional leakage from the expansible chamber due to reciprocating movement of the plunger when the engine is started.12-05-2013
20130331212TENSIONER - In a tensioner having a housing and a plunger protruding in an advancing direction from a plunger-accommodating hole formed in the housing. The plunger has a cylindrical outer wall for sliding contact with the wall of the plunger-accommodating hole, and a tapered the rear end wall. A small clearance between the cylindrical outer wall of the plunger and the wall of the plunger-accommodating hole allows the plunger to become inclined by a small amount, which increases as the plunger advances. The angle of the taper at a boundary where the end wall meets the cylindrical outer wall is substantially equal to the maximum inclination of the plunger when the plunger is in its fully advanced condition12-12-2013
