Coolant circuit, in particular a coolant circuit having a plurality of sub-circuits 1, 2, 3 of an internal combustion engine 11 includes a primary cooling circuit 1 and a heating circuit 2 as well as a coolant delivery pump 5 disposed on a rotary actuator 4, with the rotary actuator 4 having a rotary-slide housing 20 with several ports 8a, 8b, 9a, 9b, 10a through which coolant can flow, and a first and at least one second rotary slide 6 and 7 which are rotatably supported in the rotary-slide housing 20 and have each at least one rotary-slide pass-through opening 8, 9, 10 forming a flow path, wherein the ports 8a, 8b, 9a, 9b, 10a can be brought into at least partial coincidence with the rotary-slide pass-through openings 8, 9, 10 by a rotary motion of the respective rotary slide 6 and/or 7), wherein a first branch 1a of the primary cooling circuit 1 leads from the internal combustion engine 11 via a main radiator 12 to a main radiator port 8b of the first rotary slide and can be controlled by the first rotary slide 6, and that a second branch 1b of the primary cooling circuit 1 leads from an outlet 21 of the coolant delivery pump 5 to the internal combustion engine 11 and can be controlled by the second rotary slide 7. |
