ABSTRACT:
Systems, valves and methods for controlling fluid flow using the systems and the valves for applications involving the control of micro flow of fluids, such as, for example, spacecraft rocket thrusters, oil well production, medical/biological apparatus, industrial apparatus is disclosed. The valves used in the systems and in the methods include a housing having a cavity and an inlet and an outlet. A seat is positioned in the housing and connected to both the inlet and the outlet. A poppet member is positioned in the cavity relative to the seat for controlling fluid flow from the inlet to the outlet. A magnetostrictive member is positioned in the cavity and connected to the poppet member. Electromagnetic excitation means are positioned in the cavity relative to the magnetostrictive member such that current applied to the electromagnetic excitation means controls the position of the poppet relative to the seat. The systems include a controller and associated sensor(s) for measuring any one of a plurality of parameters used to control the micro flow of fluids. A method for controlling fluid flow through the valves is also disclosed.
