摘要： Disclosed is a fluid hammer tool with two separate fluid hammers in separate sections of the tool. The tool includes an upper poppet valve assembly along one fluid flow path, and a lower poppet valve assembly along a separate outer flow path. Both fluid flow paths are fed from an upper sub and both exit through a lower sub. Both poppet valves include spring return mechanisms. Sealing of each poppet valve propagates an upstream shock wave. The lower poppet valve assembly encounters greater fluid flow and generates a larger shock wave. In the period when the upper poppet valve is closed, the lower poppet valve cannot open.

摘要： The invention relates to an impact machine which is adapted to perform a hammering operation on a surface or an object to be worked upon. In particular, a vibration reduction arrangement is attached to the housing and comprises a moveable counterweight, interacting with a motion reversing arrangement having a non-linear spring characteristics, such that the motion of the counterweight can be brought into a counter-acting movement in relation to the vibrations in the housing of the hammering element thus substantially reducing the vibrations. A spring action arrangement is arranged inside said counter weight, the counter weight being movable a first distance without actuating the spring action arrangement, and the counterweight comprises displaceable projecting member for actuating the spring action arrangement.

摘要： A chisel with a bi-material blade comprising a main body of low grade steel and a cutting portion of higher grade steel. The cutting portion of higher grade steel provides longer life and decreases the need for frequent sharpening. The main body and cutting portion are connected using an arcuate interface. Additionally, the main body and cutting portion may have a radiussed cross-sectional connection. The arcuate interface and radiussed cross-section help absorb the shear and impact forces applied to the tool.

摘要： An electrical hammer (100) comprises a main housing (101), a hand grip (500) connected to the main housing (101) via a compression coil spring (321). In the electrical hammer (100), a hammer bit (119) is driven by a first motion converting mechanism (120) and thereby a hammering operation is performed. During the hammering operation, the hand grip (500) is moved against the main housing (101) in a state that biasing force of the compression coil spring (321) is applied on the hand grip (500). Further, the electrical hammer (100) comprises a second motion converting mechanism (220) which drives a counterweight (231).
