摘要： A piston rod (2) with a piston (21), against which a displaceable valve ring (23), a short, axially rigid striking pin (3), guided in a bush (24), and a pressure transformer piston (25) are set, is immovably placed in one part of the supporting housing (1). A working tool (4) is placed in the second part of the supporting housing (1) in a tool bush (27) protected on the outside by a lower sealing cover (29) to prevent corrosion. A gas chamber (45) is set up under the supporting housing (1), the pressure transformer piston (25) and the striking pin (3). A pressure transformer cylinder (43) and an equalizing chamber (44) are formed between the piston rod (2) and the pressure transformer piston (25). The striking pin (3) is driven by working fluid under pressure, which is distributed by a system of channels in the piston rod (2). The striking pin (3) is driven onto the working tool (4) in a striking action by high-pressure gas, which is pressurized in the gas chamber (45). The movement of the striking pin (3) is controlled by a switching element (20), fitted in the piston rod (2), and a valve ring (23), pushed onto the piston rod surface. It is assisted by the pressure transformer, which eliminates pressure peaks of the working fluid.

摘要： A breaching apparatus (100) includes an impactor element (106,108) and a self-contained energy source. The self-contained energy source (102) enables the impactor element (106,108) to impact a first surface of a structure. The impactor element is configured to transmit a localized shock wave through the structure upon impact. The self-contained energy source (102) is capable of accelerating the impactor element (106,108) to a velocity sufficient to induce spalling at a second surface of the structure. Multiple breaching apparatuses can be supported by a frame (704) to facilitate simultaneous or successive breaching of the structure. The breaching apparatus (100) can be used in a method to breach a concrete structure.

摘要： A pressure protection valve is provided which provides a fluid short circuit between a fluid pressure inlet of a hydraulic tool such as a hydraulic hammer and a low pressure region when the pressure at the fluid pressure inlet exceeds a first trigger pressure equal to a predetermined permissible pressure. This prevents damage to the hydraulic tool which can arise through operation at excessive fluid flow or pressure from hydraulic fluid supplied by a carrier vehicle. The pressure protection valve may maintain fluid communication between the fluid pressure inlet and the low pressure region until the pressure at the fluid pressure inlet reduces to a pressure below a predetermined second trigger pressure which is less than the first trigger pressure, to prevent further operation of the tool until the flow of fluid to the fluid pressure inlet has been stopped by an operator.

摘要： An implement comprises an internal combustion engine (1) having a throttle valve (2). At least one handle (7), the inside of which is provided with a gas lever (4) likewise in a pivotal manner, is attached to a housing (5) surrounding the internal combustion engine (1). The minimum distance between the gas lever (4) and the handle (7) is defined by a stop (9, 10). When the operator lifts the implement by the handle (7), the position of the gas lever (4) also changes. Even when the gas lever (4) is fully depressed, only a part-load position is achieved at the throttle valve (2). In this way, effective rotational speed limitation is achieved.
