摘要

The sleeve (10) has a retaining space for partially retaining movable components (12), and a vent connected with a vent channel (18) for ventilating the retaining space. The channel is partial helically formed in a longitudinal extending direction of the sleeve. The channel is connected with a collection chamber that is formed diagonal or vertical to a main extending direction of the channel. The vent and the channel are partially provided with a labyrinth seal, and the chamber partially limits the channel. An eddy current filter and/or a cyclone filter are arranged in the vent channel.
