摘要： The invention relates to a percussion device having a body and a percussion piston moving therein, pressure fluid spaces in the rear and front ends of the percussion piston and pressure fluid channels for feeding pressure fluid into the percussion device. The percussion piston and the control valve comprise surfaces, which, when aligned, substantially close the pressure fluid flow from the pressure fluid space locating behind the percussion piston in front of the control valve, whereby the produced pressure displaces the control valve to another position.

摘要： A pneumatic tool (20) for impacting a workpiece (22) is provided. The tool (20) comprises a casing (42) defining a chamber (48). A piston (54) is slidable within the chamber (48) along an operational axis (A). An exhaust valve (100) controlled by a pilot valve (200) slides the piston (54) by selectively introducing and releasing pressurized fluid into and out from the chamber (48). The pilot valve (200) includes a valve housing (202) defining a pilot chamber (204) with a plunger (206) slidable in the pilot chamber (204). The pilot valve (200) actuates the tool (20) by quickly releasing pressurized fluid from the exhaust valve (100) to atmosphere. The pilot valve (200) includes a spring-biased annular seal (214) that is releasable from a poppet seat (222) to perform this function.

摘要： A sleeve carried by and preferably slidable relative to the piston, for controlling air passages associated with a central air feed tube, whereby retraction pressure is applied to the piston substantially at impact. It is the impact itself of the piston against the bit, which enhances sliding of the sleeve relative to the piston, over the feed tube, and thereby switches the airflow at the moment of impact.

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.
