Paper Abstract

Three small, low cost piezo-hydraulic pumps have been developed. The pumps deliver up to 600 psi of blocked pressure and 338 cc/min of free flow, while the smallest weighs less than 90 grams. The pumps utilize cofired multilayer piezoelectric actuators for low drive voltages and low cost. The properties of these pumps make them suitable for distributed actuation systems where pump, control valve and hydraulic actuator are located at the point of actuation, minimizing the system weight and length of hydraulic tubing.
