<p>A rotary distribution apparatus includes a fixed inner distribution member ( 12 ) with inner conduit zone; a rotatable distribution member ( 16 ) rotatable about the fixed inner distribution member; a plurality of fluid distribution chambers ( 18 ) located between the fixed inner distribution member and the rotatable outer distribution member; each fluid distribution chamber having a fixed port ( 20 ) in the fixed inner distribution member to which a fixed supply or return conduit for a fluid can in use be connected and at least one distribution port ( 22 ) in the rotatable outer distribution member; at least one indexing arrangement ( 24 ) including a rotatable indexing member ( 26 ) and a fixed indexing member ( 28 ); a plurality of passageways ( 30, 32, 38, 40 ) extending through each of the rotatable and fixed indexing members ( 26, 28 ), the plurality of passageways each having indexing ports ( 30.2, 32.2, 38.2, 40.2 ) and connection ports ( 30.1, 32.1, 38.1, 40.1 ) with the indexing ports being provided in an indexing surface ( 36 ); and the connection ports ( 30.1, 32.1 ) of the rotatable indexing member ( 26 ) in use being connected to the distribution ports ( 22 ) of the distribution chambers by connecting conduits, and the connection ports ( 38.1, 40.1 ) of the fixed indexing member in use being connected to process chambers by fixed conduits; so that, in use, when the rotatable outer distribution member, the rotatable indexing member and the connecting conduits are rotated, fluid fed to a fluid distribution chamber ( 18 ) is sequentially fed to each process chamber and returned from each process chamber to another fluid distribution chamber ( 22 ) as the indexing ports ( 30.2, 40.2 ) of the fixed indexing member ( 28 ).</p> |
