Abstract:

The development of electro-pneumatic flow control valves for artificial limbs is described. Initially a flexible membrane type of valve was chosen for evaluation. At the small sizes necessary for prosthetic systems, the major problem highlighted was gas leakage. It is concluded that the Flexible Membrane Valve did not realise its full potential in these small sizes. An alternative of using a Flat Faced Armature Valve and producing proportional control by variation of the mark to space ratio is described, in order to present as comprehensive a range of options as possible to the designer of artificial limb systems.
