<p>A pressure reducer has a housing comprising an inlet and an outlet in which a flow-around body is arranged in a flow channel connecting inlet and outlet. A flow restrictor is adjustably mounted relative to the flow-around body for varying a flow rate and is movably connected with an adjusting means comprising a recirculating ball nut and a rotating spindle 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 rotatably mounted in the flow-around body and the recirculating ball nut is connected with a driving toothed wheel in a rotation-resistant manner, which is rotatable by an electric drive for the movable connected with recirculating ball nut.</p> |
