Abstract

Travaux publics. Le marteau piqueur se compose d'un cylindre antérieur supportant l'organe coupant réuni à un second cylindre au moyen d'un filetage particulier en dents de scie, ledit second cylindre étant introduit dans une chemise dans laquelle se déplace un percuteur mû par un ensemble approprié de soupapes ou de clapets, le percuteur heurtant l'organe coupant qui est poussé par celui-ci en produisant la perforation désirée, l'intérieur de la culasse porte un piston de culasse et un obturateur qui sont animés d'un mouvement de translation commandé par un dispositif de mise en marche, l'amortissement du marteau étant réalisé au moyen d'un anneau amortisseur qui est introduit à l'intérieur d'un raccord, le filetage extérieur du raccord étant réuni à une barre de perforation et celle-ci à la machine qui fournit l'air, un ensemble de soupapes ou de clapets protégeant le marteau lorsque l'on travaille dans les zones humides. Perforation de roche et analogues.
