Abstract

Dans le dispositif de support selon l'invention, le tube 3 d'injection d'eau de lavage repose contre le piston 2 au moyen d'éléments de support 11, 14 qui font partie du tube d'injection et qui sont conçus de manière que des canaux 16, 17 subsistent entre lesdits éléments de support en vue de l'acheminement de l'air et du lubrifiant le long du canal 6 entre le passage axial du piston et le tube d'injection. Applications : outils de perçage et forage à percussion.
