Abstract
Coolant circuit, in particular a coolant circuit having a plurality of sub-circuitsof an internal combustion engineincludes a primary cooling circuitand a heating circuitas well as a coolant delivery pumpdisposed on a rotary actuator, with the rotary actuatorhaving a rotary-slide housingwith several portsthrough which coolant can flow, and a first and at least one second rotary slideandwhich are rotatably supported in the rotary-slide housingand have each at least one rotary-slide pass-through openingforming a flow path, wherein the portscan be brought into at least partial coincidence with the rotary-slide pass-through openingsby a rotary motion of the respective rotary slideand/or), wherein a first branchof the primary cooling circuitleads from the internal combustion enginevia a main radiatorto a main radiator portof the first rotary slide and can be controlled by the first rotary slide, and that a second branchof the primary cooling circuitleads from an outletof the coolant delivery pumpto the internal combustion engineand can be controlled by the second rotary slide
