摘要： The pneumatic tool comprises a body (1) for mounting a piston (2) in a manner that enables it to slide in a sealed manner, said piston being capable of acting upon a striking element (3) mounted at the end of the body. The piston head (2a) slides inside a bore (1a) that communicates with a connecting port (1d) to a circuit for supplying air compressed by a compressor and with a discharge port (1c). The length (L) of the piston head and the positioning of the ports (1c) and (1d) are determined so that the stroke (C) of this piston is independent from the pressure.
