<p>The invention concerns a valve body for sprayer. The inventive valve is essentially characterised in that it comprises a valve-supporting sleeve (1), a connection sleeve (2) with a pouch P, and means for connecting the two sleeves. The two sleeves define a sealed channel (7) for ejecting a fluid to be sprayed, the connection sleeve (2) consisting of two walls (11, 12) shaped like curved arches joined along a plane (13), each of the two dihedrals (21, 22) tangent to the outer surface (18, 19) of the two arches and having respectively as ridges (23, 24) the two straight lines common to said two surfaces (18, 19) in the junction plane (13),having an angle at the summit (25, 26) less than 180 DEG . The invention is useful for producing a sprayer wherein the product to be sprayed is contained in the pouch P which is welded on the connection sleeve of the spraying valve body.</p> |
