Insulation device and coating system comprising said insulation device

An insulation device for a coating system for coating objects,

• wherein the coating system comprises an electrostatically operating application apparatus having a dispensing device by means of which a coating material is able to be dispensed, and at least one feed reservoir for coating material, which is connected to an input valve device via an inlet line and to the dispensing device via a supply line,
• the insulation device comprising:
• a duct having a clearing body that is movable in the duct, the clearing body having an electrically insulating material and being movable between a parked position and an insulation position,
• wherein the clearing body is configured such that, while moving from the parked position to the insulation position or from the insulation position to the parked position, the clearing body frees an inner lateral surface of the duct of material such that an electrical insulation section is able to be formed between the at least one feed reservoir and the input valve device,
• wherein the clearing body is movable by means of a fluid pressure, and
• wherein the clearing body has an insulation portion for electrical insulation and a line portion for a coating-material line so that coating material can pass through the clearing body through the coating-material line when the coating material travels from the inlet line to the supply line.
