Abstract
A hydraulic hammer is disclosed that includes at least one accumulator that is connectable to a hydraulic circuit disposed in the housing of the hammer. The accumulator includes an annular base coupled to a cover with a diaphragm sandwiched therebetween. The annular base includes a proximal end and a distal end. The proximal end of the annular base defines a first central opening. The proximal end of the base in the housing define an annular inlet that encircles the first central opening and that is in communication with the first central opening. The cover also includes a proximal end and a distal end. The proximal end of the cover is coupled to the distal end of the base with the outer periphery of the diaphragm sandwiched therebetween.
