Here are the specifics on my Dragon solenoids
This is the plunger. It is made from a lightweight, anti corrosive, magnetic material that resist everything but acid, therefor you can flow methanol,water, fuel and alcohol without corrosion.
This is how the plunger sits in the barrel. it has more sealing area so it has superior sealing over other solenoids (no leaks)
This is the nitrous barrel that I designed. It is made of a non magnetic anti corrosive material. Being non magnetic means it will not interfere with the plunger activation. This one has a .187 orifice. The barrel stays the same size for .063 through .200 size orifices. Only the exit holes need to be drilled accordingly.
The nitrous barrel has a threaded end that screws into the casing. The o ring is a hardened viton rubber that is chemical and fuel resistant.
This is the case for the .187 solenoid.
This is the coil installed onto the barrel
The nitrous and fuel going through the coil will help keep the coil cooler. There is no need for heat sinks, cooling fins or openings in the case. The col heats up from the tightest windings outward. Heat kills the magnetic force of the coil. This will help make the coil last longer.
more pics and specs coming.
