Abstract
A tensioner moves the flow restriction controlling the tensioner tuning to the nose of the piston through a hole ranging in cross sectional area from 0.01 mm2 to 1.1 mm2. It also eliminates a component from the design of the tensioner. The piston hole geometry is one or a plurality of holes.
