Abstract
A prosthetic system includes a prosthetic knee having a controller and a hydraulic unit pivotally connected to the controller. The hydraulic includes a reserve hydraulic cylinder, a brake hydraulic cylinder, and a hydraulic cylinder having a lower hydraulic compartment. A flow system fluidly connects the hydraulic cylinder, the reserve hydraulic cylinder, and the brake cylinder. The flow system has first and second flow paths in communication with the lower hydraulic compartment and the reserve hydraulic cylinder. The first flow path is in communication with lower hydraulic compartment and the reserve hydraulic cylinder via the brake cylinder. The second flow path bypasses the brake hydraulic cylinder.
