Performance Modeling and Efficiency Analysis for a Piezohydraulic Pump with Active Valves
… research, a compact piezohydraulic pump with active valves has been developed, tested and characterized. Furthermore, theoretical models are developed based on different levels of approximation of the hydraulic fluid. The first model, which assumes an incompressible and inviscid fluid, …

Piezohydraulic Actuator Design and Modeling Using a Lumped-Parameter Approach
… this unidirectional motion. Inlet and outlet valves are connected to a pumping chamber where pressure is built by the displacement of the piezoelectric material and released by the opening of the outlet valve, thus achieving a variable flow rate that is used to push a hydraulic cylinder. Loads …
