A lubrication system for rock drill machines powered by pressurized fluid, the lubricating system comprising a reservoir of lubricant, means for pressurizing the lubricant in the reservoir, conduits for feeding lubricant from the reservoir to individual dosage units, each connected to a particular lubrication point of the rock drill machine, the lubricant being supplied under pressure from the dosage unit by way of a rod- or plunger-operated piston reciprocable in the dosage unit, the end of the piston rod engaging an adjustable abutment, the dosage units being mounted such as to be reciprocable in unison with the rock drill by way of the drill feed unit.
Lubrication system for rock drill machine operated by pressurized fluid, said rock drill machine comprising a rock drill unit mounted on a slide reciprocable by power feed means relative to stationary rail means, said lubrication system comprising a reservoir of lubricant, lubricant dosage means having an input connected to said reservoir of lubricant for receiving lubricant from said reservoir, conduit means connected between lubrication points on said machine and an output of said dosage means, and means for automatically and recurrently feeding an adjustable lubricant quantity into said conduit means upon reciprocation of said slide relative to said rail, each of said dosage means comprising a cylinder into which lubricant is fed from said reservoir, a piston reciprocable in said cylinder, and a piston rod attached to said piston, said piston rod being engageable with an abutment upon reciprocation of said slide.
