Abstract
The invention concerns a reservoir capable of being periodically cleaned and/or filled with a coating product equipped with a piston (10) controlled in its movement by a control rod (11). A module (32) elastically deformable in compression (F) is incorporated in the kinematic linkage (20) between the rod (11) and the piston (10) or between the rod (11) and its actuating means, thereby providing elasticity for positioning the piston against the base of the reservoir, which enables a slight displacement of the piston rearwards when the cleaning product or fresh coating product is being injected.
