ABSTRACT:
The self-actuating fluid holding system includes a fluid pump and two fluid valves and two fluid motors all fluid-flow connected together. The valves are arranged to sense the proportionate flow therethrough and to the two motors, and when the flow is out of proportion, such as when one of the connecting lines or a connection breaks to permit the fluid to leak, then the valves have shut off closures which protect the system against fluid leakage.
