Abstract: In a valveless percussive drill of the hydraulic type and incorporating a hammer assembly, an “intermediate” shoulder between the head portion and cushion portion of a reciprocating piston engages the end face of a distributor or liner, rather than an interior bearing structure for the piston. This end face can be made harder than the ulterior bearing structure, which may include a surface made of a different material than the piston. Collectively, the result is a percussive drill with the hammer assembly incorporating the piston substantially less susceptible to failure due to galling as the result of contamination in the working fluid.
