Abstract

Marteau perforateur de fond de trou comprenant un logement, une tête postérieure et un assemblage de clapet de retenue coulissant et tubulaire comportant une extrémité distale, une extrémité proximale mâle taraudée, une entrée et un port d'échappement. Le port d'échappement établit une communication entre l'intérieur de la tête postérieure et l'extérieur de la tête postérieure. L'assemblage de clapet de retenue coulissant et tubulaire comprend un distributeur, un obturateur coulissant et un élément de sollicitation. Le distributeur est doté d'une ouverture centrale s'étendant à travers le distributeur, d'un orifice s'étendant à travers le distributeur et d'une galerie d'échappement. L'obturateur coulissant glisse le long de l'ouverture centrale. L'élément de sollicitation sollicite l'obturateur coulissant en position fermée.
