Disclosed herein are check valve assemblies with enhanced back flow protection. There are at least two duckbilled check valves (10), each having an inlet at one end and an elastomeric bill formed at an oppossite end, the bill having opposed lips and an outlet openable by a flexing of the lips apart. The bill of the first duckbill check valve is telescoped into and retained in the inlet of the second duckbilled check valve (e.g. by a jam fit or snap fit connection). These assemblies can be positioned in compact conduits such as those found in garden hose outlet nozzles.

L'invention porte sur des ensembles de clapets de non-retour pourvus d'une protection améliorée de retour de fluide. Ces ensembles comportent au moins deux clapets (10) de non-retour en bec de canard, chacun possédant un orifice d'admission à une extrémité et un bec élastomère formé à une extrémité opposée, le bec comportant des lèvres opposées, et un orifice d'évacuation pouvant s'ouvrir sous le fléchissement et l'écartement des lèvres. Le bec du premier clapet de non-retour est déployé et retenu dans l'orifice d'admission du second clapet de non-retour (par exemple, par assemblage à enclenchement). Ces ensembles peuvent être positionnés dans des conduits compacts tels que ceux placés dans les buses d'évacuation des tuyaux de jardin.
