ABSTRACT:
A dual series valve is formed with two plungers within a central bore of a solenoid. Each of the plungers is formed with a guide bore that is supported on respective guide members through opposite ends of the guide bore. The guide members are firmly supported from respective plugs in the solenoid bore to prevent the plungers from contacting the central bore of the solenoid. Two of the guide members supporting respective plungers define valve seats that are opened and closed by respective valve seals carried within the guide bores of the two plungers. The valve seats and the valve seals are maintained in alignment with each other within the respective guide bores between the guide members supporting opposite ends of the plungers.
