Valve control of pump inlet pressure bootstrap reservoir

摘要

A closed-loop system (10) includes a pump (8) driving a fluid through a series of conduits (44). A control system (52) is included that minimizes pressure fluctuations in a bootstrap reservoir (20) to maintain a desired minimum pressure at the pump inlet (32). Moreover, the control system (52) reduces a maximum system pressure by reducing the magnitude of pressure fluctuations encountered by the bootstrap reservoir (20).
