Abstract

Improvements in sets of fluid regulation valves, of the type of assemblies comprising a fluid regulation valve whose output is determined by the position of a valve control device, resilient means pushing the valve control device in direction to a predetermined position where the valve control device controls the valve to produce a corresponding predetermined outlet flow rate of the valve, characterized in that the assembly is provided with a device responsive to the fluid pressure which, only when a predetermined level of supply pressure is present, it pushes the valve control device in the opposite direction to inhibit the effect of the resilient means.
