DEVICE FOR AUTOMATIC REGULATION OF THE RUNNING SPEED OF A DRILLING TURBINE THROUGH ELASTIC ACCUMULATOR MEANS

Device for automatic regulation of the running speed of a drilling turbine, adapted to compensate for a drop in the pressure power of the drilling fluid through the turbine by an opposite variation of the flow rate of said fluid through the turbine, comprising a tank of elastically expansible volume...

Beschreibung
Zusammenfassung:	Device for automatic regulation of the running speed of a drilling turbine, adapted to compensate for a drop in the pressure power of the drilling fluid through the turbine by an opposite variation of the flow rate of said fluid through the turbine, comprising a tank of elastically expansible volume whereinto is applied the pressure of the drilling fluid, said tank being placed upstream with respect to the turbine, in the vicinity thereof and acting as a flow regulating means.
