Abstract: A fluid line system comprises fluid lines (100, 200, 300, 400). Each of the two fluid lines (100, 400) has in each case one lumen (100*; 400*) which is enclosed by a wall, and extends from a flow opening (100a; 400a), located in a respective first line end (100+; 400+), of the respective fluid line both to a flow opening (100b; 400b) which is located in a line end (100#; 400#) of said fluid line (100; 400) and also as far as a flow opening (100c; 400c) which, spaced apart from said flow opening (100b; 400b), is likewise located in each case in the line end (100#; 400#) of said fluid line (100; 400). Each of the other two fluid lines (200, 300) in turn has a lumen (200*; 300*) which is enclosed by a wall and extends from a flow opening (200a; 300a) which is located in a line end (200+; 300+) of the respective fluid line (200; 300) as far as a flow opening (200b; 300b) which is located in a line end (200#; 300#) of said fluid line (200; 300), in such a way that a greatest flow section (A200,Max; A300,Max) of the respective fluid line (200; 300) is spaced apart both from its line end (200+; 300+) and from its line end (200#; 300#). Both the fluid line (200) and the fluid line (300) are connected by way of their line end (200+; 300+) in each case to the line end (100#) of the fluid line (100) and by way of their line end (200#; 300#) in each case to the line end (400#) of the fluid line (400). The flow openings (200a; 200b; 300a; 300b) form in each case one inlet-side and outlet-side flow cross section (A200a, A200b; A300a; A300b) of the respective fluid line (200; 300). In addition, the fluid lines (100, 200, 300, 400) are configured in such a way that an outlet-side flow cross section (A100,min; A100,min) of the fluid line (100; 400) which is located at the line end (100#; 400#) of the fluid line (100; 400) and adjoins both the flow opening (100b; 400b) and the flow opening (100c; 400c) of said fluid line (100; 400) and flow cross sections (A200a; A200b; A300a; A300b) overall fulfil the conditions: (I) and (II), and (III) and (IV).

Abstract: A flow divider comprises a lumen having perpendicular, symmetry planes intersecting in an axis of inertia connecting the ends. Cross sectional area have radii extending from a geometric center of gravity to the wall and lying at an angle φ (−180°≤φ≤180°) to a reference axis and being perpendicular to its axis of inertia, wherein each radius lying at an angle φ=0° to the relevant reference axis points away from the symmetry plane, and fulfills a formula fi(φ, Pi) associated with its cross sectional area and defined by a coefficients set Pi (Pi=[ai bi m1i m2i n1i n2i n3i]) corresponding to the flow divider opening: R i ( φ ) = R 0 · r i ( φ ) = f i ( φ , P i ) = f i ( φ , [ a i b i m 1 i m 2 i n 1 i n 2 i n 3 i ] ) = R 0 · ❘ "\[LeftBracketingBar]" 1 a i cos ( m 1 i 4 φ ) ❘ "\[RightBracketingBar]" n 2 i + ❘ "\[LeftBracketingBar]" 1 b i sin ( m 2 i 4 φ ) ❘ "\[RightBracketingBar]" n 3 i - n 1 i , in such a manner that the radii R4(φ) of a cross sectional area of the lumen fulfills a formula f4(φ, P4) defined by a coefficients set P4=[a4 b4 m14 m24 n14 n24 n34], with a4=(0.95 . . . 1), b4=(0.45 . . . 0.7), m14=4, m24=4, n14=3.0, n24=n14 and n34=(3 . . . 4).
