Abstract

Device for regulating the feed force for a rock-drilling unit of the type including a drilling rod (12) with a bore crown, a fluid-driven pressurized rock-boring machine (11) for the rotating and striking effect of the drilling rod (12), a feed motor (17) for feeding the drilling rod to or from the rock and a device for supplying a means of flushing to the scavenging ducts (23) in the bore crown (13). The invention is especially characterized by the flushing device containing a flow indicator (25) for sensing flow through the scavenging ducts (23) and that the given flow indicator (25) has a control device connected to the feed motor (17) for reversing of this if the flow goes under a predetermined level.<IMAGE>
