ABSTRACT:
A regulating valve, comprising a housing having a cylindrical valve chamber, is disclosed. The valve chamber is provided with at least one inflow and at least two outflow ports. The inflow and the outflow ports can be at least partly closed off as required by a single common valve body arranged in the valve chamber that can rotate about an axis. The valve body acts as a rotary valve and can be actuated by a drive. The inflow and/or at least one of the outflow ports is surrounded on the side of the housing facing the valve body by a seal. The seal can be brought into sealing engagement with the valve body under an elastic preload. The valve body has an extension in the peripheral direction of the valve chamber that is delimited in each case by an edge, such that the flowoff edge passing over the inflow port while it is opening has an axially extending elliptical indentation.
