ABSTRACT:
A hydraulic chain tensioner has an air vent. The tensioner includes a housing having a fluid filled chamber and a hollow plunger slidably received within the chamber and biased in a protruding direction by a spring. The plunger has an upper end with an aperture. The vent includes a disk biased by the spring against the inside of the upper end of the plunger. With the disk having at least one channel formed on at least one side of the disk. The channel has a first end at the periphery of the disk and a second end at a position to establish a connection between the atmosphere and the chamber through the aperture in the upper end of the plunger.
