Abstract: An active, vibration-countering mount assembly for a vibrating component is disclosed. The mount assembly comprises a supported mount supported on a machine element, a supporting mount supported via a spring element on the supported mount, and an inertial mass, movable back and forth by means of a drive parallel to the direction of the vibrations introduced by the vibrating component. The inertial mass is joined to the supported mount by a spring such that the inertial mass and the spring are not contacted by a liquid.
Abstract: A method of making a shaft seal ring starts with a tube, optionally provided on its outside and/or inside with hydrodynamically-acting return elements, as may be cut from a hollow cylinder. The tube is axially slipped along a form with a continuously increasing diameter until its leading or lower end is shaped into a flange in the radial direction. The flange may be simultaneously joined to a reinforcing ring.
