Abstract
A hydraulic tensioner for a traction device (1) having a pressure chamber (2) in a housing (3), into which a medium that transmits pressure can be introduced, having a feed unit (5) having a non-return valve (6) at one end (4) of the pressure chamber and having an overpressure relief device (8) at the other end (7) of the pressure chamber (2), wherein the overpressure relief device (8) includes a closure element (11), a housing body (9) and a cage (10) which is at least partly arranged within the housing body (9) and which forms a stop for the closure element (11) on the side remote from the pressure chamber, wherein the cage (10) at least partly covers an end side of the housing body (9) that is remote from the pressure chamber. The invention also relates to a traction device drive having such a tensioner for a traction device.
