ABSTRACT:
A prosthetic knee device having a hydraulic cylinder with a piston and a gas cylinder. A connecting element extends outwardly from the piston and passing through a gas cylinder. A bottom portion of the gas cylinder is adapted for slidable engagement with the hydraulic cylinder. A plunger is fixedly connected to the hydraulic cylinder. An outer periphery of a plunger is adapted for slidable engagement with the interior surface of the gas cylinder, so as to form an operational chamber within the gas cylinder between the bottom portion thereof and the plunger. The operational chamber is responsive to the movement of the prosthetic knee device.
