ABSTRACT:
A hydraulic power actuator system flow augmentation scheme of the boot-strap type. The scheme consists of a jet pump to augment pump inlet flow with return flow by reducing the pressure in the jet pump below return pressure. A check valve is installed in the augmentation circuit to prevent back-flow during low flow rate conditions. Two load recovery check valves are used to short circuit the actuator during aiding load conditions.
