Abstract
A fluidic stiffness enhancing circuit for use with a fluid driven piston type actuator includes a fluid conduit arrangement that interconnects two variable volume chambers of the actuator upon occurrence of a loss of system pressure to at least one of the chambers. The fluid conduit arrangement incorporates an inertance device for controlling the rate of flow of fluid therethrough so as to control the pressures in the two chambers in response to external forces applied to the actuator piston and thereby the stiffness of the actuator.
