摘要： The invention relates to a striking device (5) comprising a striking mechanism (8) which is driven by a pressure medium. Said device comprises a percussion piston (13) which can be displaced back and forth by means of a control device and a control valve which is embodied as a pressure shut-off valve (19) or as a stop valve, said control valve automatically stopping the striking mechanism if it exceeds a predetermined maximum value based on the working pressure controlling the inlet line, blocking the pressure line (3) or maintaining the control device in one of the end positions thereof. The inventive striking device also comprises a hydraulic catcher buffer which is used to brake the percussion piston when it exceeds a predetermined impact plane. According to the invention, the control valve must remain deactivated at least as long as the percussion piston is displaced on the hydraulic catcher buffer.

摘要： The present invention relates to a hydraulic attachment comprising a hydraulic circuit, the attachment being a construction or demolition tool, in particular a hydraulic breaker, demolition shears, scrap shears, a pulverizer, a gripper, a crusher bucket or a compactor, which can be mechanically connected to a support device and hydraulically connected to the hydraulic system of the support device. In order to enable the hydraulic circuit to be opened quickly and safely within an attachment and, in particular, to make it possible to display the presence of a particular pressure level within a hydraulic attachment and to determine whether a dangerous residual pressure is present in the system, a hydraulic attachment is proposed that has a residual pressure display (40) which is connected to the hydraulic circuit of the attachment in a detachable or non-detachable manner.

摘要： The invention relates to a percussion device comprising a percussion mechanism housing which has a receiving bore in which a percussion piston is mounted such that it is movable along the longitudinal axis, wherein at least one percussion mechanism guide surface having an inner diameter is formed in the receiving bore and at least one percussion piston guide surface having an outer diameter is formed on the percussion piston. In order to avoid radial contact between the percussion piston and the percussion mechanism housing as far as possible, to reduce the volume of oil leakage through the gap of the guide surface and to prevent wear on the guide surfaces and on the lands between the seals, according to the invention the percussion mechanism guide surface has, at least in some regions, an inner diameter that increases non-linearly in the axial direction and/or the percussion piston guide surface has an outer diameter that decreases non-linearly in the axial direction.
