Patent ID: 10054200

Abstract:
An assembly comprising: a fixed support such as an engine block, a plurality of pulleys mounted rotatably on the support a belt mounted on said pulleys a tensioner comprising: a plate a rotary element mounted on the plate via a rotating shaft fixed relative to said plate, the tensioner being capable of turning relative to the support, in a predefined direction of rotation, between an idle position in which the rotary element is separated from the belt and an operating position in which the rotary element is in contact with the belt, it being specified that, in the operating position, the belt exerts a force on the rotary element, the direction of said force tending to rotate the tensioner in said same predefined direction of rotation; at least one stop for preventing the tensioner from rotating in the predefined direction of rotation beyond the operating position of same, the latter thus being defined by the stop; wherein in order to rotate the tensioner relative to the support between the idle position and the operating position of the tensioner, the assembly comprises: at least one closed port arranged on the plate of the tensioner or on the support at least one means for engaging with the or each closed port, said engaging means being fixed relative to the support when the closed port is located on the plate or fixed relative to the plate when the closed port is located on the support.
