Abstract: A device for automatically regulating the operation of a drilling turbine which drives a tool and is supplied with hydraulic fluid at an essentially constant rate of flow from a source of fluid. The device includes a duct in the form of a bore provided in the shaft of the turbine wherein the lower part of the bore terminates in the immediate vicinity of the tool, a first communicating member directly connecting the source of fluid with an inlet of the turbine to provide a flow path for the hydraulic fluid therethrough and a second communicating member for providing a flow path for hydraulic fluid to the tool. The second communicating member includes at least one orifice having a variable cross section for communicating between the inlet of the turbine and the upper end of the duct, the cross section being variable in accordance with an operating parameter of the turbine to regulate the flow of hydraulic fluid to the inlet of the turbine and to the tool.
