  • Pilot solenoid valve
    Patent number: 5996629
    Abstract: A valve installation surface of a manifold base includes an installation surface on which a main valve and two pilot valves and are installed, separate from each other. The manifold base includes a supply channel, ejection channels and an output port that opens to a front end surface, all opening to the main valve installation surface. One end of pilot supply passages and communicates with pilot supply and ejection channels and, respectively. The other ends of pilot ejection passages and are open to the pilot valve installation surface. One end of pilot output passages and opens to the pilot valve installation surface, while the other ends are open to the main valve installation surface. A manifold base may also include a waterproof cover that covers the pilot valves and the energization system, extending from the feeding line to the pilot valve. The main valve may be a single or double solenoid.
