Nozzle arrangement, nozzle carrier and device for extruding doughy substances

Nozzle carrier having a nozzle arrangement for extruding doughy substances, comprising

• an axis of rotation (26),
• an inner nozzle (14), which is disposed coaxially with said axis of rotation (26) and has a mouth (16) for extruding an inner substance (56), and
• two outer nozzles (18, 19), which are disposed axially offset relative to said inner nozzle (14) and are rotatable about said axis of rotation (26) and each have a mouth (20;
• 21) for extruding an outer substance (58, 59), wherein
• the nozzle carrier (10) comprises two parts, which are rotatable relative to one another, namely
• a stator, in which an inner feed channel (22) as well as a first (24) and a second outer feed channel (25) are formed, and
• a rotor, which carries the nozzles (14, 18, 19), is first rotatably supported in said stator and contains a first connection channel (62), which connects said inner feed channel (22) to said inner nozzle (14), characterized in that
• in at least one of the said parts, which are rotatable relative to one another, a first annular space (28) and in the rotor a second connection channel (63) are formed, which connect the first outer feed channel (24) to the first outer nozzle (18), and a second annular space (29) is formed, which connects the second outer feed channel (25) to the second outer nozzle (19).
