Patent abstract
In a hydraulic tensioner, an oil pressure control recess, at a proximal end of a cylindrical, plunger-receiving hole, receives from an oil supply, and also receives oil which oozes past a check valve and an inner sleeve inside the plunger, thereby returning the oil, which would leak to the outside in a conventional hydraulic tensioner, to the interior of the plunger.
