Abstract

Improvements in percussion tools characterized by the combination in combination of a percussion tool provided with a frame, a working cylinder formed in said frame and a hammer piston movable alternately in said working cylinder by the pressure of a fluid, a member in that no vibrations should occur, pneumatic means for transmitting the force between said member and said frame, and means for automatically adjusting the value of said force in order to keep said members and frame in a relative predetermined average situation, and to maintain such value relatively constant during a considerable number of reciprocating movements of said hammer piston.
