摘要： An impact tool has a slidable hammer that is driven by hydraulic oil under pressure inside a chamber. The hydraulic oil is pressurized by a piston driven by compressed gas on the opposite side of the piston from the hydraulic oil. The gas in the gas chamber is compressed by the piston on an initial stroke, and has a large annular chamber holding the gas so that higher average gas pressure can be attained during the power stroke. As the piston is moved to compress the gas, the piston lifts a valve that opens a passage for the hydraulic oil moved by the piston to act on a hammer to impact a breaking tool. The piston is a two part piston that serves to lower the inertia during the final closing of the valve, and thereby reduces impact loads on the valve as it is closed. The valve also is controlled as to its stroke for efficient operation.

摘要： A hydraulic percussive machine, for example a jack hammer or a rock drill, has an accumulator with a flexible diaphram (35). A lift valve (40, 41, 42) closes the outlet of the accumulator if the flow exceeds the normal flow substantially and it traps a volume of oil between the diaphragm and the valve when it closes.

摘要： A cylinder (15) is reciprocable in the housing (11) of a hydraulic percussive tool and a piston hammer (16) is reciprocable in the cylinder. The force between the cylinder and the housing is constant during the cycle of reciprocation and as a result the housing (11) is practically not vibrating at all. The piston hammer (16) and the cylinder (15) are coupled together to move conjointly during a part of each forward stroke of the hammer piston, which ensures the timing of the reciprocation of the hammer piston 16 and the cylinder (15).

摘要： A hydraulic percussion or an impact apparatus for driving rock-breaking tools, drill bits and ramming or tamping tools comprises a body in which an end of the tool is received and a reciprocating mass formed as a piston which is axially displaceable in a cylinder. The cylinder is provided with a distributor member slidable above the piston and of the same diameter as the latter, the distributor being formed as a sleeve having a central portion engaging a collar of a plunger which extends into a piston and forms therewith a suction chamber. The plunger has an extension which is slidable in a bore of the body and is acted upon by the high-pressure fluid.

摘要： A pressure indicator for a hydraulic hammer is provided. The pressure indicator includes a sleeve member configured to couple to an opening defined in a wall housing of an accumulator of the hydraulic hammer. The pressure indicator further includes a plunger slidably disposed within the sleeve member and movable between a first position and a second position with respect to the sleeve member. The plunger includes a first end disposed outside the wall housing of the accumulator. The plunger further includes a flange coupled to a second end. The pressure indicator further includes an elastic member inserted over the plunger and disposed between the wall housing of the accumulator and the flange. A position of the first end of the plunger with reference to an outer end of the sleeve member provides a visual indication of the pressure of the gas within the accumulator.
