<p>A pressure reducer(1) has a housing(4) comprising an inlet(2) and an outlet in which a flow-around body (5)is arranged in a flow channel(6) connecting inlet and outlet(3). A flow restrictor(7) is adjustably mounted relative to the flow-around body for varying a flow rate and is movably connected with an adjusting means(8) comprising a recirculating ball nut (9) substantially fixed in an axial direction and rotatably mounted in the flow-around body and a rotating spindle(10) is axially adjustable mounted in said recirculating ball nut wherein the rotating spindle is movably connected with said flow restrictor. To improve such a pressure reducer that a corresponding flow restrictor with a facilitated construction is reliable and can exactly be adjusted in position, the recirculating ball nut is detachably fastened to a turning sleeve(11) rotatably mounted in the flow-around body and the recirculating ball nut is connected with a driving toothed wheel(59) in a rotation-resistant manner, which is rotatable by an electric drive(58) for the movable connected with recirculating ball nut.</p> |
