A hydraulic, pneumatic, or electric tool may include a spindle that is adapted for rotational movement. A swing arm may be coupled to the spindle such that the rotational motion of the spindle is transferred to the swing arm. The swing arm may make contact with an anvil such that the rotational motion of the swing arm causes the anvil to move along a linear path. A piston may be operatively coupled to the anvil to follow the linear movement of the anvil. The piston may be adapted to interact with an energy storage medium when the swing arm moves the anvil in the first direction, causing energy to be stored. As the swing arm continues to rotate, the swing arm may lose contact with the anvil, thus allowing the energy storage medium to urge the piston and the anvil in a second direction opposite the first direction. |
