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.

Rotary valve comprising a drawing device

The present invention relates to a rotary valve for conveying and metering bulk material into a pneumatic conveying conduit. Exemplary embodiments include a housing with a supply opening, a discharge opening and a cellular wheel supported rotatably about a substantially horizontal axis within a cavity of the housing. The cellular wheel rotates in a predetermined direction of rotation so that as some of its cells move upward, other cells move downward. The housing has at least one venting opening for venting the upward moving cells, the venting opening being arranged before the supply opening when seen in the direction of rotation. A perimeter of the at least one venting opening lies on a peripheral wall of the housing and has a plurality of recesses which extend in a direction towards the cellular wheel when the latter rotates in the direction of rotation.
