ZWEIKANALIGE DREHDURCHFUEHRUNG ZUM UNABHAENGIGEN BEAUFSCHLAGEN VON DRUCKRAEUMEN IN UMLAUFENDEN SYSTEMEN

摘要

A fluid feed device comprises a hub (2) with central feed channel (3) which opens into a first pressure chamber (5) and a plurality of parallel feed channels (4) which are arranged around the central channel and open into second pressure chambers (6). The channels (3, 4) are supplied by way of ducts and annular grooves in the hub (2) and in a non-rotating annular member (7) which surrounds the hub. To accommodate axial tolerances, the annular member (7) and a coaxial cover (8) adjacent thereto each have a respective pair of claws, which are oriented towards each other and disposed in slidable engagement in a cross-slotted sheave (12). The channel arrangements (31 to 37; 41 to 47) open out in the claws and these channel arrangements are connected by means of connecting ducts which extend in the sheave (12) and open out at slot faces covered by the claws. <IMAGE>
