Abstract
A three position fast acting solenoid which may be coupled to a spool valve with a center null position. The spool of the valve is moved to one of three positions by a momentary signal to either of two coils. The spool is held positively in each end position by magnetism, and in the center position by a mechanical stop, so that the valve requires no electrical input except when the valve is changing from one position to another.
