Electrofluid converter

摘要

An electrofluid converter converts electrical energy into fluid energy by controlling the linear expansion of a wire that is used as a fluid control valve. Thermal linear expansion of the wire is brought about by passing an electric current through the wire thereby increasing or decreasing the portion of the wire within the fluid flow path. The converter can be used in applications that require converting electrical proportional or digital signals into corresponding fluid signals. The converter signal may be used to control fluid amplifiers or other fluid sensors.
