Abstract
A fast-response three-way solenoid valve. A housing has three openings interconnected by a linear fluid pathway, with two chambers each disposed between two openings and having at least one valve seat per chamber. In each chamber a ball is movable toward and away from a valve seat to open and to close off the flow of fluid there. A separator pin is disposed, with clearance, within the linear pathway between the two chambers and bearing against both balls; when one ball is seated against its seat, the other ball is away from its seat. A solenoid has a plunger which moves upon energization of the solenoid, and a guide passage between the plunger and one chamber is aligned with both chambers and the balls. A plunger pin disposed in the guide passage bears against one ball on the side thereof opposite to the separator pin; the other end of the plunger pin bears against the plunger when the solenoid is energized. Movement of the plunger upon the energization of the solenoid causes the plunger to contact and move the plunger pin, in turn moving the balls and their separator pin, so that one ball is seated when the solenoid is energized, and the other ball is seated when the solenoid is de-energized.
