Abstract:
1. A fluid intake pressure regulating system having a master header connected to first and second fluid discharge lines and being connectable to a pressurized fluid source, said first fluid discharge line being connected to a pump for delivering fluid from the pressurized fluid source, through the pump, and to a secondary header, and said second fluid discharge line being connected to a reserve tank, comprising: a flow meter connected to the secondary header and being adapted to deliver a signal (A) in response to fluid flow through the header; a pressure transducer connected to the master header and being adapted to measure the fluid pressure within the master header and deliver a signal (B) responsive to said measured pressure; a master control valve connectable to the pressurized fluid source and to the master header and being adapted for controlling the fluid passing into the master header; a secondary control valve positioned in the second fluid discharge line between the master header and the reserve tank and being adapted for controlling fluid passing from the master header and into the reserve tank; means associated with the reserve tank for measuring the fluid level within the reserve tank and delivering a signal (C) in response to said measurement; a micro processor having a manual set point and being electronically connected to the flow meter, the pressure transducer, the measuring means, the master control valve and the secondary control valve and being adapted to receive signals (A–C) and deliver controlling signals (D and E) to the master control valve and secondary control valve respectfully and responsively control the fluid pressure entering the pump, maintain the reserve tank in a full condition, and prevent fluid having undesirably high fluid pressure from discharging from the secondary header.
