Abstract

In a multi-chamber device a chamber with lubricant is sealed off on a rotationally drivable component from a second chamber at a peg of a power tool, by at least one seal sliding at a contact face, and least one stationary component is provided in the chamber with lubricant before the contact face and surrounds a rotationally drivable component at least over a region of a circumference to substantially prevent turbulence in the lubricant in a region of the contact face.
