Abstract

To expand the operational capabilities of hydraulically actuated systems the development of new valves capable of enhanced flow rates and bandwidth performance is required. In previous work, the solution to achieving desired flow rates was to increase valve spool size and travel, but this is at the expense of the dynamic response. To increase flow without restricting dynamic performance, this paper roposes the use of multiple metering edges achievable using the H¨orbiger plate valve principle, actuated by piezoelectric means. Experimental results from a piezoelectric actuated valve are then used to demonstrate improved performance in both static and dynamic operation.
