  • Patent number: 4120234
    Abstract: A device for distributing pressurized fluid to first and second movable consumers while maintaining a fixed ration between the fluid flows to the consumers, including rotary flow value gauges for directing a return flow from each consumer to an associated gauge, a comparator interconnecting the gauges without one gauge being dependent on the other gauge as to the rotation of the gauges and sensing differences between the output flow of the gauges, inlet valves activated by the comparator to regulate the flow to each consumer for maintaining the fixed flow ratio, and throttle valves for the return flow from each consumer and activated by the comparator to throttle the return flow from a consumer to slow down such consumer.
