Abstract :
The paper describes the components of a fuel and air supply system for a micro combustor. Liquid gas from a fuel cartridge is regulated by a micro valve, ejected from a nozzle, and then supplied, with air, to a micro combustor. The valve is composed of a largely-deformable corrugated diaphragm regulating fuel gas and two electrostatic valves controlling the corrugated diaphragm to realize low pressure loss, low power consumption and low driving voltage. The CFD (computational fluid dynamics) simulation of the ejector was performed, and compared with real experiments. The CFD simulation results fairly matched with the experimental results. The micro valve was fabricated and preliminarily tested. The pressure loss is as low as 11 Pa/sccm, and the electrostatic valve controlled butane with a pressure of 220 kPa at a driving voltage of 40 V.
