Machine tool with a chamber for lubricating agent and a pressure equaliation device for said chamber

摘要

The present invention is directed to a machine tool, in particular to a hand-operated hammer drill, having a compartment (10) containing lubricant in which at least one rotationally drivable component (12) is mounted and having a device (14) for compensating the pressure in the compartment (10), the device having a rotationally drivable centrifugal component (16) which shields at least one pressure-compensation channel (18) disposed downstream from it, in terns of fluid mechanics in the venting direction of the compartment (10). It is proposed that the centrifugal component (16) be mounted in a torsionally fixed manner on the rotationally drivable component (12).
