A theory of non-linear compliant mechanisms has been developed that can be applied to macro and micro structures. This theory has been applied to the development of an automotive positive crankcase ventilation valve and tested against current production valves to manufacturer's specification. Tests have shown that this new valve costs less, is less susceptible to hysteresis and is impervious to flutter instabilities and failure by freezing. This paper discusses the testing procedures and results of this new valve developed at the Massachusetts Institute of Technology.
