Abstract:
1. A valve device having a plurality of solenoids and comprising: a solenoid portion having magnetic attracting faces for attracting a movable valve at one ends of fixed cores disposed in coils; a valve body portion connected to the solenoid portion and having an input flow path and an output flow path for pressurized fluid; the movable valve being made of paramagnetic material to open and close a valve seat between both the flow paths, the valve device carrying out opening and closing of the valve seat by the movable valve according to actuation of the solenoid portion, wherein the solenoid portion has the plurality of solenoids having the attracting faces of the fixed cores arranged to be adjacent to each other on the same plane and a common magnetic frame covering the solenoids and having a top panel portion in contact with end faces of the respective fixed cores on opposite sides to the attracting faces, wherein an opening portion surrounded by the valve seat of the output flow path for the pressurized fluid in the valve body portion slenderly extends in an arranged direction of the plurality of solenoids, and wherein the movable valve has a portion facing at least the respective fixed cores and attracted by the fixed cores when the plurality of solenoids are energized, and a device for seating the movable valve on the valve seat when the energization is cancelled.
