Abstract
A deflector valve for fluids directs fluid flow from an inlet port into either of two outlet ports. Deflection of the fluid into the desired outlet port is controlled by piston means which typically are operated by a solenoid. A unique operating pin, shaped like an hourglass, provides mechanical engagement between the piston means, and also facilitates the flow of fluid in the desired direction. The piston means are spring-biased, so that the valve selects one of the outlet ports in the de-energized state. The other outlet port is selected when the piston means encounter an external force opposing the spring.
