A flow regulator, preferably in a respirator/ventilator, has a conduit through which a medium conduit flow is to be regulated flows and a choker valve arranged outside the conduit, the choker valve having pressure applicators arranged exactly opposite one another between which the conduit can be brought and act on the flow cross-section of the conduit such that they leave the flow cross-section of the conduit uninfluenced in a first limit position and press the conduit completely closed in a second limit position. In order to obtain a flow regulator of this type with a choker valve that is gentle on the conduit and which can also completely compress a conduit having a comparatively large flow cross-section, the pressure applicators are fashioned such that, when the conduit is compressed, both pressure actuators actively press it together from both, opposite sides.
