Abstract
A rotary valve comprising a stator with an inner stator face, and a rotor with an inner rotor face arranged in sealing contact with the inner stator face, the rotor is rotatably movable to a plurality of rotor positions about a rotational axis relative to the inner stator face, the stator comprises a plurality of connection ports each being in fluidic contact with a corresponding valve orifice at the inner stator face and the rotor comprises two or more interconnection paths for selective fluidic interconnection of said valve orifices with respect to the rotor position, wherein the stator comprises, an inlet port, an outlet port, a component feed port, a component return port, and wherein the interconnection paths in the rotor are arranged to: —in a first rotor position interconnect the inlet port with the outlet port, —in a second rotor position interconnect the inlet port with the component feed port and the component return port with the outlet port, —in a third rotor position interconnect the inlet port with the component return port and the component feed port with the outlet port.
