Abstract

See full text

A regulator pump provides disconnects an inflow from an outflow, such that a downstream pressure is unaffected by an upstream pressure. The regulator pump receives a fluid through an input valve, while an output valve remains in a closed position. The fluid continues to flow to the regulator pump until the regulator pump is full. With the regulator pump filled with the fluid, the inlet valve shifts to a closed position, thereby isolating the regulator pump chamber from the fluid source. The regulator pump drives the fluid downstream to an applicator with the inlet valve closed. The regulator pump fully isolates the upstream fluid from the downstream fluid such that the upstream pressure has no effect on the downstream pressure.
