Abstract (en)

[origin: US2003136586A1] An apparatus having a housing (5) that shields a front of a percussion drive (1) against the environment, and into which a drive driven tool (3) projects. An exchangeable outer seal (10) is disposed at the housing opening (6c) for the tool (3), surrounds the tool transversely to its longitudinal axis (3a) with spacing, and is moveable in this transverse direction. An inner seal (11) is disposed behind the outer seal (10), and rests elastically against the tool (3) outside of its tool guide (2). The inner seal (11) is exchangeably secured to an elastic extension (12) of the tool guide (2) that surrounds the percussive tool (3) in the region of the inner seal (11) with a spacing larger than the largest transverse displacement of the tool (3). The extension (12) is an independent, elastic support that forms a detachable connection with the tool guide (2) at one end.
