Abstract
Apparatus for spraying a fluid, including a pipe, a scraper capable of moving in the pipe, and a casing defining a storage volume for accommodating the scraper in a position for storing the scraper, the scraper being configured to push fluid in front of it which is present in the pipe when the scraper moves in the pipe, the storage volume being in fluid communication with the pipe and being configured to allow the scraper to move between the storage volume and the pipe. The scraper includes a first magnet, and the casing includes a second magnet capable of exerting a first force on the first magnet to move the scraper from the storage volume to the pipe.
