         9 . The jet regulator ( 1 ) as claimed in,  claim 1 , wherein the splitter unit ( 4 ) has a splitter plate ( 14 ) or a diffusor, or is configured as a splitter plate ( 14 ) or diffusor. 
     
     
         10 . The jet regulator ( 1 ) as claimed in,  claim 1 , wherein the water guide ( 5 ) terminates above a discharge structure ( 22 ) of the jet regulator ( 1 ), or is routed through a discharge structure ( 22 ) of the jet regulator ( 1 ), or an integrally molded, screen element ( 23 ) is at least one of: disposed or configured in the water guide ( 5 ). 
     
     
         11 . The jet regulator ( 1 ) as claimed in  claim 1 , wherein the jet regulator ( 1 ) in the region of the water guide ( 5 ) has at least one of: at least one attachment screen ( 10 ) or at least one screen insert ( 20 ). 
     
     
         12 . The jet regulator ( 1 ) as claimed in  claim 4 , wherein the splitter unit ( 4 ) and the attachment screen ( 10 ) are releasably or non-releasably connected to one another, by way of a snap-fit connection, or the anchoring element ( 11 ) is releasably or non-releasably connected to the splitter unit ( 4 ), by way of a snap-fit connection. 
     
     
         13 . The jet regulator ( 1 ) as claimed in  claim 1  wherein the two ducts ( 2 ,  3 ) on an inflow side have inlets ( 24 ,  25 ) which are mutually separate, or the two ducts ( 2 ,  3 ) on an outflow side have outlets ( 26 ,  27 ) which are mutually separate.
