Controller of flow rate has installed concentrically body and bushing that form inlet and outlet cavities. On cylindrical surface of bushing radial channels are provided. Shutoff-control elastic body is installed in input cavity and is arranged as thin-wall cup on the bottom of which control screw is placed. Walls of thin-wall cup are formed with circular lugs provided on the inner surface of the bushing and radial channels, control throttles. Cavity between the bushing and thin-wall cup is through throttle connected to input cavity. Inside thin-wall cup adjustment spring is placed. Control screw is placed on the outer surface of the core. Throttle connecting inlet cavity to cavity between the bushing and thin-wall cup is made controlled.
