The present study describes an improvement of damping performance of a mechanical tensioner driven by friction force at the power spring interface. used for the timing chain system for an internal combustion engine. The mechanical tensioner consists of a power spring subjected to face-to-face contact with a reciprocal motion and a leaf spring to apply the reaction load. The concave an... https://poolsproductscanadas.shop/product-category/pentair-eq-series-parts/
