Abstract
A hydraulic breaking hammer (10) has a machine housing (11) in which a percussion motor (15) which includes a reciprocatingly movable percussion piston (17) delivers impacts to a breaking tool (13) in the front of the machine housing (11). The machine housing (11) is carried by a surrounding carrier support (18) via intermediate walls (24, 25, 26). The carrier support has the form of a shell (18) which is attached at the rear adjacent connecting devices (19), to a carrier, such as a hydraulic digging machine which aligns the machine housing (11) while the manner (10) is at work. The machine housing (11) is constructed without joints in its axial direction along the length of the housing and includes a guide passage (21) in which a percussion motor (15) is carried, this percussion motor having the form of an insert cartridge which can be clamped from the rear. The shell (18), the intermediate walls (24, 25, 26) and the machine housing (11 ) are all combined in a single one-piece metal casting and the space between the shell (18) and the machine housing (11) is filled with a sound-damping material which adheres to the housing (11) and surrounding parts. Hydraulic fluid communication with the percussion motor cartridge (15) is effected through annular grooves (44', 45', 46') provided in the guide passage (21).
