Abstract
The present invention relates to a fluid distribution arrangement (100), comprising: at least three fluid guides (107, 107-1, 107-2, 107-3, 107-4) which are designed to guide fluid, wherein the at least three fluid guides (107, 107-1, 107-2, 107-3, 107-4) are formed in a valve housing (101) of the fluid distribution arrangement (100), a valve housing (101) which delimits a housing interior (103), wherein the valve housing (101) has at least three housing openings (105, 105-1, 105-2, 105-3, 105-4), which each connect the housing interior (103) with a fluid guide (107, 107-1, 107-2, 107-3, 107-4) of the at least three fluid guides (107, 107-1, 107-2, 107-3, 107-4) fluidically connect, wherein the respective housing opening (105, 105-1, 105-2, 105-3, 105-4) is each limited by an opening edge (109) of the valve housing (101), a valve piston (111) which is rotatably arranged and formed in the housing interior (103),to at least partially fluidically block or at least partially fluidically release the at least three housing openings (105, 105-1, 105-2, 105-3, 105-4) depending on a piston position of the valve piston (111), at least three sealing arrangements (117, 117-1, 117-2, 117-3, 117-4), wherein in each case one of the at least three sealing arrangements (117, 117-1, 117-2, 117-3, 117-4) is arranged in one of the at least three fluid guides (107, 107-1, 107-2, 107-3, 107-4) at one of the at least three housing openings (105, 105-1, 105-2, 105-3, 105-4), wherein the Sealing arrangements (117, 117-1, 117-2, 117-3, 117-4) each have a fastening element (119) and a sealing element (121), wherein the respective fastening element (119) rests against an inner wall (123) of the respective fluid guide (107, 107-1, 107-2, 107-3, 107-4) and is designed to apply a force to the respective sealing element (121),to press the respective sealing element (121) against the respective opening edge (109) of the valve housing (101) and to effect a fluidic seal between the valve piston (111) and the respective opening edge (109).
