Abstract

A hydraulic impact device comprises a housing (10) with a cylinder (11) and a hammer piston (13) guided in the cylinder (11) and reciprocated by a hydraulic control system including a directional valve (18) and a pressure accumulator (19), wherein the pressure accumulator (19) comprises a pressure chamber (20) divided into two compartments (20a, 20b) by an elastic flexible membrane (21), and a movable membrane support (24) formed by a disc element (26) with a convex contact surface, and a spring (28) acting both as a biasing means and a guide means for the disc element (26), said spring (28) is positively located relative to the disc element (26) by a circular recess (30) in the latter and by a tubular neck portion (29) on the housing (10).
