Abstract
A belt or chain tensioner comprises a plunger that is slidably received in a chamber of the tensioner housing. The plunger is biased by a spring to project out of the housing and into contact with a tensioning shoe by which tension is applied to the chain or belt. The chamber is supplied with hydraulic fluid to damp movement of the plunger within the housing. The spring is captively connected between the plunger and housing and located outside of the housing. The tensioner is simple to install and remove from an internal combustion engine as the plunger and housing are held together by the spring.
