Abstract (en)

[origin: WO0222315A1] The invention relates to a machine tool, in particular a hand-operated hammer drill, comprising a chamber (10) with lubricating agent and a pressure equalising device (12, 14, 34) for the chamber (10), in the region of a bearing (16, 18, 36) for a rotating driven component (20, 22, 54). According to the invention, the bearing (16, 18, 36) forms at least part of a lubricating agent seal (24, 26, 38) for the pressure equalisation device (12, 14, 34), by means of which a pressure in the chamber (10) may be equilibrated.
