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

摘要

A machine tool, in particular to a hand-operated hammer drill is described. The tool has a compartment containing lubricant in which at least one rotationally drivable component is mounted and having a device for compensating the pressure in the compartment. The device has a rotationally drivable centrifugal component which shields at least one pressure-compensation channel disposed downstream from it, in terms of fluid mechanics, in the venting direction of the compartment. The centrifugal component is mounted in a torsionally fixed manner on the rotationally drivable component.
