ABSTRACT:
The device has, inside a duct (11) through which flows an incompressible fluid, a first profiled throttling element (17), a differential piston (10) subjected on one side to the pressure upstream of the profiled element (17) and on the other side to the pressure reduced by the element (17), a profiled surface (18) on the piston on the side subjected to the reduced pressure and a second profiled element (16) which are intended to interact to reduce the passage of fluid as a result of the movement of the piston in a first direction and increase the loss of head substantially, and a spring (15) returning the piston (10) in its second direction of movement. The device can serve particularly for actuating a stabilizer of a set of drill rods. In this case, the differential piston has inclined slopes.
