Abstract
A solenoid valve comprises spring loaded poppets that selectively seal an inlet supplied from a pump and an outlet that exhausts. The spring loaded poppets are carried by an armature in axially aligned relation and maintain both the inlet port and outlet part normally closed, wherein the armature is movable to open one of the inlet or outlet while the other remains closed. Two independent solenoid coils are provided to move the armature in opposite directions, wherein the armature is movable interiorly of the bobbin and has sufficient stroke to displace and seat one poppet or the other. The solenoid coils are selectively energized to pull the poppet away from its respective seat on the inlet or outlet to allow selective flow to and from a communications port for selectively pressurizing and depressurizing the communications port and interconnected components such as one or more air bladders.
