Abstract
A valve bank has a coil pack assembly with multiple solenoid coils bound to one another by a single resin body. An L-shaped magnetic (but not magnetized) bracket is also bound within the body and extends between upper pole pieces of the valves and the manifold in which the valves are mounted. A retainer plate holds the valves in the manifold, and helps complete the magnetic flux path circuit from the manifold end of the bracket to the lower pole pieces of the valves. A spring clip helps position the manifold end of the bracket close to the retainer plate. A circuit board for individually energizing the coils is also potted within the resin body.
