Abstract
Hydraulic breaker hammer comprising a housing (10) with a longitudinal bore (12), a cylinder sleeve (14) mounted in the bore (12), a hammer piston (15) sealing guided in the cylinder sleeve (14), a guide sleeve (21) located in the front end portion of the bore (12) for receiving a working implement, and a rear end cover (16) forming a closure for the rear end of the bore (12). The rear end cover (16) comprises a tubular neck portion (17) which is formed integral as a one piece member with the end cover and which extends into the bore (12). The neck portion (17) forms a guide means for the hammer piston (15), and the bore (12) having an axially facing annular shoulder (18), wherein the cylinder sleeve (14) is supported in a correct operating position between the shoulder (18) and the end cover neck portion (17).
