Abstract
A hand-operated electrostatic spraygun comprises a gun body, a pistol tube of insulating material, a handle, an insulation-clad high-voltage generator and a connection for paint delivery and is contructed such that the gun is particularly small, lightweight and can be effortlessly held in the hand. The gun body, preferably composed of aluminum, is an essentially cylindrical body which comprises the connection for paint delivery in the region of its forward end adjacent its forward face. The pistol tube, preferably formed of plastic, is secured to the forward face of the gun body in a manner to be secured against twisting and comprises a clover leaf-shaped cross section having two to four "leaves". The high-voltage generator is secured at the rear region of the end body to the underside thereof, whereby the cladding of the high-voltage generator is shaped as a pistol grip and forms a handle for the spraygun.
