Abstract

This device (6) is placed beneath the feed hopper (4) of a spraying installation and serves to feed the gun. It includes: - a flexible connecting conduit (hose) (9) which bears against a fixed surface and connects the outlet of the hopper (4) to the inlet of the conduit (2) bringing the mixture to the gun; - a movable assembly which is moved in the direction of discharge of the product and is fitted with protuberances (20, 21) squashing (compressing) the tube (9) in a sealed manner, so that the air contained in the said tube (9) is forced out via the front and creates a suction action at the rear; - a compression element (22) which is placed downstream of the feed hopper (4) and makes it possible, when the movable assembly moves and releases the squashing of the tube (9), to prevent back-flow towards the hopper (4). <IMAGE>
