Abstract: A general electro-rheological valve is disclosed used in controlling the flow of fluids in a variety of applications. The valve comprises an inlet in communication with a fluid source, an outlet for transporting the fluid out of said valve, and an oscillating valve member for opening and closing off said inlet. The valve member has a cavity containing an electro-rheological fluid, a perforated electrode member emersed in the electro-rheological fluid within the cavity, and means for electrifying the perforated electrode member such that the electro-rheological fluid within the electrode solidifies, thereby locking the position of the valve member relative to the electrode. In this manner, the valve member, which oscillates with respect to the perforated electrode member, can be frozen in an open, closed, or intermediate position with respect to the inlet. The valve member thereby controls the level of fluid flow through the valve.
