Abstract
CETTE INVENTION CONCERNE UN COUTEAU POUR RABOT DEPLACE LE LONG D'UN FRONT DE TAILLE AFIN D'ASSURER L'ABATTAGE DE CHARBON OU D'AUTRES MINERAUX. CE COUTEAU COMPORTE AU MOINS UNE BUSE DE COUPE ASSURANT LA PROJECTION SUR LE FRONT DE TAILLE D'UN JET D'EAU A HAUTE PRESSION. CETTE BUSE PEUT ETRE CONJUGUEE A UNE MISE OU ARETE DE COUPE EN METAL DUR PREVUE SUR LE COUTEAU. LE CORPS DE LA BUSE EST MONTE DE FACON AMOVIBLE DANS UN PERCAGE DU COUTEAU ET SON EMBOUCHURE SE TROUVE A UNE CERTAINE DISTANCE DE LA SURFACE EXTERIEURE DE CE COUTEAU. ELLE COMMUNIQUE AVEC CETTE SURFACE PAR UN ALESAGE DE SORTIE AYANT UN DIAMETRE NETTEMENT SUPERIEUR A L'ALESAGE DE LA BUSE. UN AGENCEMENT DE CE TYPE ASSURE UNE DECOMPRESSION DU CHARBON PAR LA FORMATION D'UNE SAIGNEE POUR FACILITER SON ABATTAGE MECANIQUE.
