Abstract

A percussion apparatus has a housing that shields a front of a percussion drive and into which a drive driven tool projects, exchangeable outer seal disposed at housing opening, and inner seal disposed behind the outer seal. The inner seal is exchangeably secured to an axial extension of tool guide. The extension forms a detachable connection with the tool guide at one end. A percussion apparatus comprises a fluid operated percussion drive. A housing part shields the percussion drive, at least at the front, against the environment, and into which a percussive tool driven by the drive projects axially into a tool guide of the drive. An exchangeable outer seal id disposed at an opening provided in the housing part of the tool. The seal surrounds the tool, transversely to its longitudinal axis, with at least some spacing, and is seated for movement in the transverse direction. An inner seal is disposed behind the outer seal, when seen counter to the direction of action of the tool, and resting in an elastic manner against the tool, outside of the guide. The inner seal is secured, so as to be exchangeable, to an axial extension of the tool guide in the direction of the action of the tool. The extension surrounds the percussive tool in the region of the inner seal, with a spacing that is larger than the largest possible transverse displacement of the percussive tool in the housing. The extension is an independent, elastic support element that, on its rear side facing away from the inner seal, has a beginning segment (12c) that forms a detachable connection with a receiving segment (2a) of the tool guide in the longitudinal and transverse directions. The extension latches in the receiving segment of the tool guide that is designed to secure the extension in a snap connection.
