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.
Claims10
Device for spraying coating product, comprising at least one sprayer (1) and a reservoir (4) provided with a piston (10), the displacement of said piston being controlled by an actuating rod (11), while the bottom (14) of said reservoir is connected by at least one channel (15) to a supply (16) of cleaning product and/or of fresh product, characterized in that it comprises a module (32), elastically deformable in compression (F), incorporated in the kinematic linkage (20) between said rod and said piston or between said rod and its drive means (12), said module allowing a movement of recoil of said piston during the introduction of product in said reservoir from said channel (15) and in the direction of the front face (13) of said piston.
