The liquid from the working container (3) flows via working pipeline to an operating installation for a paint-spray gun, as a result of applying pressure to the liquid in the working container (3). According to an advantageous embodiment of the invention, after a preset filling height has been reached in the storage container (2), the working container (3) is topped up until a preset filling height is achieved in the working container (3), said filling height in turn enabling or triggering the refilling of the storage container.
