摘要：
A rotary valve for selectively connecting at least one component (51, 52) into a fluid path. According to the invention the inner stator face (I l ia, 211a) comprises orifices (131b-136b; 231b- 236b) and said inner rotor face (112a, 212a) comprises at least a first groove (121, 221), a second groove (122, 222), and a third groove (123, 223) so arranged that the rotary valve can take at least three different rotary positions, in which either both components are bypassed, only one of the components is connected and the other bypassed or both components are connected to a main flow.
