Abstract

L'invention concerne un appareil de percussion à coussin d'air présentant un carter (1) dans lequel un piston d'entraînement (2) et un piston frappeur (9) sont guidés de manière à effectuer un déplacement dans le sens axial. Le mouvement du piston d'entraînement (2), produit par un mécanisme à manivelle, est transmis au piston frappeur (9) par l'intermédiaire d'un coussin d'air dans une première chambre (10), ledit piston frappeur (9) venant heurter de manière cyclique une bouterolle (11) ou un outil. Le mouvement de retour du piston frappeur (9) renvoyé par la bouterolle (11) est assisté par une augmentation de la pression de l'air dans une troisième chambre (15) qui est alimentée en air par le piston d'entraînement (2) par l'intermédiaire d'une deuxième chambre (14) et d'un canal de communication (13).
