Abstract
An automatic regulator of hydrostatic pressure for incorporation in vertically extending pipes, comprises a nozzle 10 for connection to upstream piping and having a flared orifice C opening into a turbulence chamber 8 having an outlet which is connected via branch piping 11, 12, 13, 14 to an inlet of a cylinder 1 for connection to downstream piping. A piston 2 in the cylinder carries a valve member 5 which extends into the turbulence chamber and has a tapered head for co-operating with the flared orifice of the nozzle to control the flow from the nozzle in dependence upon the difference in force exerted by the pressures acting on a downstream end of the piston and on the head of the valve member. A safety valve 14 is provided in the branch piping. <IMAGE>
