摘要： In order to provide a seal for sealing a sealing gap between a first component and a second component, comprising a seal body with at least one sealing portion and at least one spring element for biasing the sealing portion against at least one of the components to be sealed, the spring element being at least partially arranged in a receiving space of the seal body, which seal is simply constructed and easily producible and nevertheless ensures a secure retention of the spring element in the receiving space, it is proposed that the spring element has at least one claw element, by means of which the spring element is interlocked with the seal body.

摘要： The present invention relates to a hydraulic auto-tensioner, in particular for a chain drive of an internal combustion engine, comprising a housing, a tensioning plunger guided in a plunger bore of said housing, a free piston guided in said plunger bore, and a plunger rod formed on said tensioning plunger and extending through the free piston. The tensioning plunger, the housing and the free piston delimit a hydraulic reservoir which is sealed with respect to the housing and the plunger rod by means of a sealing unit that is arranged on the free piston. The sealing unit is implemented as a double seal ring with an outer sealing surface which is in sliding contact with the plunger bore of the housing, and an inner sealing surface which is in sliding contact with the plunger rod of the tensioning plunger. In addition, the present invention relates to the use of such a double seal ring in a hydraulic auto-tensioner.
