Hydraulic hammer with compressed gas store to operate piston has upper end of piston in fluid-filled first chamber separated from second chamber by membrane

摘要

The hydraulic hammer has a compressed gas store to operate the striker piston. The upper end (19) of the striker piston (2) runs into a first chamber (11) filled with fluid. This chamber is separated by a membrane (12) of elastic material from a second chamber (10) filled with compressed gas and forming the compressed gas store.
