Abstract (en)
Device for the continuous delivery of dense and/or viscous substances, in particular adhesives of the polymerizable type, comprising a tubular delivery body (5) with a cylindrical rod (4) coaxially sliding, alternately, inside it by means of a double-acting piston (2), so as to create an annuler cavity (6) connected to a source supplying adhesive under pressure, said rod being provided with substantially conical obturator means (8a) at its free end which comprises, coaxially with the said conical obturator (8a) and in the vicinity thereof, at least two sealing members consisting of enlarged parts (10, 13), integral with said rod (4) and sliding inside chambers or countersunk zones (11, 14) formed in the internal surface of the tubular body (5), there also being provided at the opposite end of said annular cavity (6) at least one other sealing member consisting of a cylindrical body (17), coaxial with said rod (4) and sliding inside a chamber (16) of larger diameter formed inside the cylindrical body. <IMAGE>
