ABSTRACT:
An oil tensioner for applying a tensile force to chains, belts and similar wrapping type power transmitting mechanisms. The tensioner includes an oil reservoir for storing oil drawn from an engine block to a cylinder of a piston via a check valve, and returned to the reservoir via an orifice. The valve and orifice allow the piston to move more readily in one direction than in the other. A bell-shaped oil filter disposed adjacent to the bottom of the reservoir filters out chips and dust as well as controls the rate of oil outflow thereby preventing air from being drawn into the cylinder with the oil, and providing smooth oil flow and possible damage to the components.
