About the control port 13 takes place in dependence on the rotational position of the rotary valve 6 a connection from the inlet opening 9, 10 or 11 to the collection port 7 and thus a connection to the suction side of the impeller 3 of the water pump.
  • FIGs 4 to 7 are different control positions the control device 1 shown. So shows Fig. 4 shows the position in normal operation "cooling".
  • Fig. 5 is a first mixing operation in the warm-up phase of the engine during simultaneous heating operation, wherein the inlet opening 9 of the radiator line shut off and the inlet openings 10 and 11 for the Short circuit circulation line and for the heating circuit are open.
  • Fig. 6 shows a second mixing operation in the phase "warm-up and cooling", where the heating circuit is shut off.
  • FIG. 7 shows a third mixing operation in FIG Phase "heating and cooling", wherein the inlet opening 10th is shut off for the short circuit circuit line.
  • heating circuit can also be a second Short circuit, e.g. for the cylinder head, provided his.
  • the rotary valve 6 can be any circuit switch separately. In addition, between each two circuits set any mixing stages his.
  • inlet openings 9, 10 and 11 are all three inlet openings 9, 10 and 11 in the same radial plane, which achieves a very short construction length becomes.
  • a circumferential opening can also be used as a partial circuit for an additional heater or an exhaust gas heat exchanger provided his. Also combinations of different subcircuits are self-evident in the context of the invention possible.
