摘要：
Oil is supplied to the compressed air supply hose (15) for a jack leg rock drill (10) by means of a conventional in-line oiler (16). A substantial part of the oil is separated from the drive air by means of a wall flow separator (30,31) at the drill and conveyed through internal passages (35) in the drill to various parts to be lubricated such as a chuck (25) and a ratchet mechanism (26) for rotating the chuck.
