Patent ID: 7644877

Claim:
A diffuser device, particularly for a sprinkler for dispersing liquids, comprising: a support body that is at least partly hollow and defines a longitudinal axis; a connection sleeve for connecting to an external liquid feed line, said sleeve being designed to be removably coupled to said support body; a convergent nozzle accelerating a liquid, said nozzle being interposed between said support body and said sleeve; a deflector member located in said support body downstream of said nozzle, said deflector member diverting liquid flow so as to distribute the liquid outwardly; and primary connection means for removably coupling said nozzle to said support body while preventing an accidental separation thereof upon mutual coupling of said sleeve with said body, the primary connection means being formed both on the support body and the nozzle, thereby allowing a fast and easy periodic replacement of the nozzle in the diffuser device, wherein said nozzle has a substantially frustoconical longitudinal portion, from which one or more transverse extensions extend radially therefrom, said transverse extensions being designed to be slideably inserted in corresponding longitudinal slots of said connection portion pertaining to said support body.
