    • A portable electrostatic spray gun for liquid and/or pulverulent materials has a body with a grip and a second portion which carries a detachable barrel and has an inlet for admission of material to be sprayed. The rear side of the grip has a socket for a first unit of the high-voltage generator. A second unit of the generator is installed in a chamber provided in the second portion of the body and being accessible upon separation of the second portion from the grip. The grip contains a proximity switch which is actuatable by the trigger and can be deactivated by rotating it in the grip. The first unit of the generator has a transformer and an oscillator connected to a low-voltage input, and the second unit has a voltage multiplier connected with two high-voltage electrodes, one in the inlet and the other in an air admitting channel which is provided in the second portion of the body and includes a passage in the second unit of the generator.
    • 用于液体和/或粉末材料的便携式静电喷枪具有带有手柄的主体和携带可拆卸筒的第二部分,并具有用于容纳待喷涂材料的入口。 手柄的后侧具有用于高压发生器的第一单元的插座。 发电机的第二单元安装在设置在主体的第二部分中的室中,并且在将第二部分与把手分离时可接近。 手柄包含接近开关,该接近开关可由触发器启动,并可通过在手柄中旋转而使其不起作用。 发电机的第一单元具有变压器和连接到低电压输入的振荡器,并且第二单元具有与两个高压电极连接的电压倍增器,一个在入口中,另一个在空气导入通道中, 设置在主体的第二部分中并且包括在发电机的第二单元中的通道。
