Abstract (en)
This comprises a marking tool (3) comprising a tip (5) attached to a piston (9) which slides inside a cylinder (10). Cyclical control means (CC) alternately move a shutoff element (13) at a specific frequency into the closed or open position. In the open position, the tool (3) is pushed by a pressurised fluid acting on its piston (9) in such a way that its tip (5) strikes the object intended to be marked. With the shutoff element (13) in the closed position, the piston is brought back to its initial position at the top of the cylinder (10) by return means. <IMAGE>
