ABSTRACT:
In an oil-operated tensioner, oil from s reservoir formed in the tensioner housing passes through a check valve to a chamber behind a spring-urged plunger, which protrudes from the housing to maintain tension in a chain or belt. Instead of the usual press-fit cup for closing the opening of the reservoir, a flat or convex cover plate is fixed to the housing for closing the opening in the reservoir.
