Conveying assembly i.e. roll-cell pump for delivering fuel, has compensation channel connecting groove chamber with working chamber, and enlarging end section facing working chamber, where channel runs diagonally with respect to flute base

摘要

The assembly has a pump chamber (12) including grooves provided in a sealing body (28), where the grooves include a flute base and two side flanks. The grooves are guided in a radial direction with respect to a rotating axis in a track. A compensation channel connects a groove chamber with a working chamber. The groove chamber is enclosed between the base and the body, and the working chamber is enclosed in a rotating direction. The channel enlarges an end section that faces the working chamber, where the channel runs diagonally with respect to the base.
