Abstract
A rotary valve includes a housing having a housing bore which can be laterally closed by bearing covers. Inside the housing, a cellular wheel is rotatably supported. A guiding device extends in an axial direction of the cellular wheel and serves for drawing the cellular wheel in the direction of its axis of rotation out of the housing bore. This guiding device includes an additional bearing which can be displaceable in the axial direction relative to that bearing cover which is on the guiding side. The additional bearing serves to support the cellular wheel temporarily during removal from the housing bore. This additional bearing can be connected to that end of a cellular wheel shaft which is situated at the side of the guiding device.
