Abstract

A rotating valve is provided that includes an inlet region having a plurality of stationary separate inlets for several flows of a fluid and an outlet region having an in particular identical plurality of stationary separate outlets for the flows of the fluid, wherein between the inlet region and the outlet region a switching region having a switching member that can be rotated about an axis is provided, wherein in a first position of the switching member the plurality of inlets are connected to the plurality of outlets in a first association, and wherein in a second position of the switching member the plurality of inlets are connected to the plurality of outlets in a second association, wherein the switching member comprises a plurality of openings through which the fluid flows flow axially in the direction of the rotation axis and which are moved together with the switching member, the openings alternately covering a plurality of stationary, axially directed openings in the course of the rotation of the switching member, wherein the different associations of the inlets with the outlets are carried out by the alternating covering of the axially directed openings.
