Abstract
A valve apparatus for controlling fluid flow comprising a substrate having a first aperture extending therethrough for defining a first fluid flow path; a beam having first and second terminal end portions mounted in fixed relationship with the substrate and having a bucklingly displaceable intermediate portion positioned in overlying relationship with the aperture for covering and uncovering the aperture for preventing or enabling fluid flow through the aperture; and a temperature control assembly for selectively controlling the temperature of the beam for selectively bucklingly displacing the intermediate portion of the beam for controlling fluid flow through the aperture.
