Abstract

Controller of flow rate has body, control throttles and shutoff-control springy device installed in the inlet cavity and arranged as thin-wall cup. Output cavity between the body and the shutoff-controlled springy device through controlled throttle is connected to input cavity. To change rigidity, in the thin-wall cup adjustment spring is placed. Control screw is placed at the outer surface of the core. Input and output cavities are formed by installed concentrically body and shutoff-control springy body. Control throttles are formed with connection of opening in the body and respective number of rectangular channels that are concentrically placed on the left end of thin-wall cup and are arranged as radial slots.
