摘要：The invention relates to a hydraulic motor (), comprising a cylindrical motorhousing () with a central cylindrical rotor () carrying longitudinal vanes (), wherein thevanes () are provided at the outer surface of the rotor () in such a manner that they can
protrude into an annular space between the housing () and the rotor () in order to createa circumferential driving force on the rotor, wherein the housing () comprises inwardspointing salient cams () on its inner surface, which separate the annular space betweenthe housing () and the rotor () into several hydraulic chambers () with at least one inlet ()and at least one outlet () for a hydraulic medium, and the vanes () can swing around alongitudinal axis that is mostly parallel to the rotation axis of the rotor () into thehydraulic chambers (). The invention further relates to the use of such a hydraulic motorin a drilling system, and a drilling system with such a hydraulic motor.
