Abstract

Electrostatic spray gun in which the electrical path is in part through the fluid to be sprayed, the spray nozzle at least and optionally the fluid container as a whole being insulating and electrical connection being made with the fluid prior to its emergence from the nozzle, the fluid to be sprayed being expelled from the container (8) by a piston (56, 57) having a lubricating and sealing fluid (60) between axially inner and outer parts (56, 57). <IMAGE>
