Precision Fluid Dispense Valve

US Patent:
4489863, Dec 25, 1984
Filed:
Feb 11, 1982
Appl. No.:
6/347843
Inventors:
Leonard A. Horchos - Poughkeepsie NY
Harold W. Lorber - Poughkeepsie NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
F16K 3108
US Classification:
222504
Abstract:
A micro dispense valve arrangement for accurately dispensing minute quantities of a fluid. The valve arrangement interfaces an enclosed interior region under pressure with an exterior region of less pressure through an orifice opening. The orifice wall is tapered from interior to exterior to bound a frustoconical region constricting toward the exterior to accommodate a magnetizable pellet or ball. The ball is held in its seated position against the orifice wall by permanent magnets imbedded in the wall. An AC coil surrounding the orifice opening acts when energized to cause the ball to move between its seated or closed position and a non-magnetizable screen in its open position. The frequency and duration of applied positive and negative pulses driving the coil act to control the on/off fluid flow duty cycle of the valve.
