Three-way, two-position in-tube solenoid gas valve assembly

Abstract

A new three-way, two-position in-tube solenoid gas valve assembly comprises a modified in-tube solenoid gas valve and a pair of gas release valves is designed to control pneumatic systems. The modified in-tube solenoid gas valve is a modification based on the previous invention by Wang et al., U.S. Ser. No. 10/924,789. The new modifications are first adding a rod-piston assembly onto the solenoid assembly, a new inlet was added to the valve tube and two outlet fittings were also added. With these modifications, the systems can now work with two directions of gas flows, which is important to control pneumatic systems. To be able to control pneumatic systems properly, two gas release valves are included as part of the assembly. The goal of these two gas release valves is to be able to release gas from pneumatic quickly and completely. These gas release valves are operated based on two compression springs and through gas inputs into the valves. The operations of the gas releases valves are simultaneously while one opens the other closes. The opening and the closing of the gas release valve depends on the state of the modified solenoid gas valve.
