Abstract
The present invention concerns an improvement to devices for regulating the flow and the pressure of compressed gases in order to save energy. The device according to the invention comprises a main body whose inlet nozzle is connected to a main seat on which a main valve is adapted to come to rest, said main valve being integral with a valve-chamber and being returned to its seat by means of an elastic member, a secondary valve being adapted to occupy an opening position to allow the flow of gas from the pressure user apparatus whose rate of flow is controlled by a nozzle provided in the main valve. The invention finds an application in the control of jacks.
