ABSTRACT:
A tensioner for adjustably exerting tension upon a flexible member such as a chain or belt. The tensioner comprises a housing having a piston cavity with an actuating piston reciprocally mounted therein. A spring biases the piston in a direction outwardly of the housing. Both the piston and the housing carry a guide shoe thereon for engaging the flexible member. The piston has a flat face cut therein that defines a first stop and a second stop. A pin is positioned parallel to the flat face to restrict axial movement of the piston to within the constraints of at least one stop, and to also prohibit rotational movement of the piston within the cavity.
