ABSTRACT:
A fluid distribution system is described including a plurality of utilization devices, such as water sprinklers or drippers, supplied with pressurized fluid, characterized in that the inlet pressure to the utilization devices is substantially equalized by the provision of pressure-equalizer valves. Each valve includes means for producing a pressure drop having a first component compensating for the pressure change due to the elevation of the utilization device, and a second component compensating for the pressure drop due to the distance of fluid flow to the utilization device. Also described are pressure-equalizer valve constructions producing pressure drops having the above two components.
