Abstract
A rotating valve includes an inlet region, an outlet region, and a switching region having a switching member that can be rotated about an axis. In a first position of the switching member the plurality of inlets are connected to the plurality of outlets in a first association, and in a second position of the switching member the plurality of inlets are connected to the plurality of outlets in a second association. The switching member has a plurality of openings through which the fluid flows flow axially in the direction of the rotation axis and are moved together with the switching member. The openings alternately cover a plurality of stationary, axially directed openings in the course of the rotation of the switching member. Different associations of the inlets with the outlets are carried out by the alternating covering of the axially directed openings.
