<p>1. Distributor for a pasty product comprising : a) a body (20; 120; 320) which is made up of a tubular body and a piston (59) sliding in the interior of this tubular body and, at its top (19, 119; 319) a suction valve or closure (48 and 50) for aspirating the pasty product into a compression chamber (55) ; b) a distribution head comprising : - elements bounding the compression chamber (18 and 32; 118 and 132; 318 and 335 and 332 and 363) - an actuator (1) fixed to an upper pipe (37; 137; 237) of the deformable element (18; 118; 318) bounding this compression chamber (55), said actuator (1) cooperating with said element (18; 118; 318) which allows it to be driven in, bringing about a reduction in the volume of the compression chamber (55), and which produces the return of the actuator (1) into the upper position, said actuator (1) bearing a distribution duct (8) ; - an expulsion valve (38 and 32; 138 and 132; 363 and 309) for expelling the pasty product in the distribution duct (8) placed at the outlet of the compression chamber (55) ; characterised in that the actuator (1) comprises, on the one hand, an external tubular part (2; 102; 302) fixed on the top (19; 119; 319) of the body (20) and surmounting this top and, on the other hand, a push-piece (3; 103; 202; 303) bearing a lateral driving-in stop (8; 108; 208; 308) as well as said distribution duct (8), said push-piece being fixed to the outlet of the compression chamber (55) and also comprising a lateral external wall (33) allowing its axial sliding and its rotation in the interior of said external tubular part (2; 102; 302), which comprises an upper edge (23) preventing the driving-in of the push-piece when said lateral stop surmounts said edge (23) and at least one cut-out (6) in which this lateral stop (8) engages in the driving-in position of said push-piece, said cut-out (6) therefore limiting this driving-in.</p> |
