Abstract
A sealing arrangement for providing a seal between a component and a cylinder in which the component is inserted includes a sealing ring supported in the axial direction in a circumferential slot on the component. The sealing ring has at least one static and one dynamic sealing lip. The sealing lips rest radially on corresponding sealing surfaces of the component and the cylinder. To reduce the noise generated during movement of the component in the cylinder, the geometrical shape of at least of one of the sealing lips is asymmetrical in the axial and/or radial direction with respect to a longitudinal axis of the component or a plane perpendicular to the longitudinal axis of the component, or cavities are distributed around a circumference of a base body portion of the sealing ring.
