摘要： The invention is directed to a controllable pressure reducing valve (1) having a housing (2) which includes an inner chamber (3) extending in the direction of a longitudinal axis and having an inlet opening (15) and an outlet opening (17), said inlet opening (15) and said outlet opening (17) opening into the inner chamber (3) at an axial relative distance, and said inner chamber (3) including between the mouths of the inlet opening (15) and the outlet opening (17) at least one annular wall (11) having a cylindrical valve bore (20) and an axially movable valve body (4) which is arranged in the inner chamber (3), extends through the valve bore (20) and has a piston-type portion (29) guided in the valve bore (20) and adapted to close the valve bore (20). The piston-type portion (29) includes at least one control recess (45) bounded by a control step (46) which extends in axial direction and in circumferential direction and combines with an edge of the valve bore (20) to form a controllable valve opening.The pressure reducing valve (1) is particularly well suited for the generation of pressure change signals adapted to be transmitted to a downhole location in a mud pump supply conduit connected to drill pipes, with the inlet opening (15) of the pressure reducing valve (1) being connected to a bypass conduit branching off the supply conduit of the mud pump, and the outlet opening (16, 17 or 18) being connected to a return conduit leading to a mud pit.

摘要： The invention is directed to a turbine (3) for generating power in a drill string (2), including a turbine rotor (10) drivable by a fluid and a bypass device having a first bypass channel bypassing the turbine rotor (10). For varying the volumetric flow through the bypass channel, provision is made for a valve (28) and a control device driven by the fluid and having a drive element (24) by means of which the valve (28) is movable anywhere between a first and a second position. The drive element (24) produces a flow resistance in the fluid flow path downstream from the turbine rotor (10) and downstream from the valve (28) and in the flow direction takes support upon a spring (26).
