the nozzle body shown in context of the nozzle in fig4 is also shown in a specification form in fig5 the nozzle body 60 is a cylinder with a hollow passage 62 and made of a conductive material inserted through openings in the gas delivery pipe 42 and attached at the back end 66 by a screw on liquid attachment cap 43 the front end 67 of the nozzle is then inserted through the nozzle opening of the cylindrical shell 12 and attached by a lock nut 46 a middle section 69 of the nozzle body when fitted into the gas delivery pipe 42 will be inside of the gas delivery pipe 42 the gas delivery pipe 42 is then sealed by the use of gaskets 51 that ring the nozzle body 60 at the outside of the gas delivery pipe 42 the nozzle body 60 is pushed all the way through the gas delivery pipe 42 until the nozzle anchor 57 prevents further insertion the nozzle body being conductive delivers the high voltage signal from the gas delivery pipe 42 to the electrode 56 which is also conductive the nozzle body provides one half of the means for connecting the electrode to the nozzle body by its electrode threaded screw mount 64 the hollow passage 62.
