Abstract:
A rock drilling machine includes a sleeve having openings surrounding a portion of a lubrication channel. A groove surrounds the sleeve, and one end of a second channel is connected to the groove. The other end of the second channel is connected to a lubrication point so that lubricant from the lubrication channel is distributed from the lubrication channel, through the sleeve and groove to the second channel, and from the second channel to a lubrication point of the rock drilling machine.
