CA 2621483

An impulsive unit (12) for a jack hammer (10) or rock drill (80, Figs 2 and 3) is adapted to be powered by water, and comprises a piston (34) slidable within a cylinder (32), and carrying a striker portion (35) thereon. At least a portion of the piston and/or cylinder is coated with ceramic. The ceramic is most suitably an aluminium oxide-titanium dioxide composite, which enables the clearance between the internal diameter of the cylinder and the external diameter of the piston to be reduced to between 8 and 10 micro-metres.

La présente invention concerne une unité d~impulsions (12) pour un marteau perforateur (10) ou perforateur mécanique (80, figures 2 et 3) qui est conçue pour être actionnée de façon hydraulique, et comprend un piston (34) qui peut coulisser à l~intérieur d~un cylindre (32), et qui supporte un percuteur (35) sur celui-ci. Au moins une partie du piston et/ou cylindre est enduite avec de la céramique. La céramique est de façon la plus appropriée un composite d~oxyde d~aluminium-dioxyde de titane, qui permet à l~espace mort entre le diamètre interne du cylindre et le diamètre externe du piston d~être réduit à une distance comprise entre 8 et 10 micromètres.
