Abstract

L'invention a pour objet un outil à percussion. Il comprend un corps ayant une partie intermédiaire 10 à laquelle est incorporé un distributeur principal 11, un manchon 13 qui déborde du corps intermédiaire et qui sert au montage d'une partie arrière 20 et d'une partie avant 21; dans ce corps est monté un piston 14 qui sert en même temps de marteau pour frapper sur un burin 26 sous l'effet d'un fluide compressible comprimé dans une chambre 23 limitée par la partie arrière 20 du corps L'invention est utilisable sur les machines d'exploitation des mines nécessitant des outils compacts et d'entretien facile.The subject of the invention is a percussion tool. It comprises a body having an intermediate part 10 in which is incorporated a main distributor 11, a sleeve 13 which protrudes from the intermediate body and which serves for mounting a rear part 20 and a front part 21; in this body is mounted a piston 14 which serves at the same time as a hammer to strike on a chisel 26 under the effect of a compressible fluid compressed in a chamber 23 limited by the rear part 20 of the body The invention can be used on mining machines requiring compact and easy-to-maintain tools.
