Abstract
Slide ring seals have the problem that they generate noise under certain conditions of use. In order to suppress this noise in an effective way, the slide ring seal has at least one damping part that comprises at least one shaped sheet metal part. It is provided with at least one elastically deformable spring part that is supported under pretension. Between the damping part and the support area microfriction is generated that leads to an effective noise damping action. The slide ring seal is advantageously used in the automotive field.
