Abstract
In one embodiment, a reciprocating tool includes a first variable volume fluid chamber, a second variable volume fluid chamber in fluid communication with the first variable volume fluid chamber, a plunger configured to modify the volume of the first variable volume fluid chamber by movement generally in a first direction along a plunge axis such that a portion of a fluid moves from one of the first and second variable volume fluid chamber to the other of the first and second variable volume fluid chamber, a counterweight configured such that the movement of the portion of the fluid results in a movement of the counterweight generally in a second direction along the plunge axis, the second direction opposite to the first direction, and a chuck assembly supported by the plunger.
