Abstract

An insulation device for a coating system for coating objects, the coating system having an electrostatically operating application apparatus having a dispensing device which dispenses a coating material, and at least one storage container which is connected to an input valve device via an inlet line and to the dispensing device via a supply line. The insulation device comprises a channel with a physical body which can move in the channel. The physical body has an electrically insulating material and can be moved by means of a fluid pressure between a park position and an insulation position and is designed such that, when it moves from the park position to the insulation position or from the insulation position to the park position, the physical body removes material from an inner casing surface of the channel, so that an electrical insulation path can be formed between the storage container and the input valve device.
