ABSTRACT:
A fluidic actuator includes dual-element, differential area pistons consisting of a power piston and an extender piston that are mounted in a double-chamber cylinder. A spring-loaded throttling plunger is slidingly mounted in a longitudinal bore in the power piston to meter the flow of pressurized fluid against to the extender piston as a function of the incremental stroke length of the extender piston.
