Abstract

1408806 Rotary positive-displacement fluidmachines DANFOSS AS 16 Aug 1973 [18 Aug 1972] 38731/73 Addition to 1395817 Heading F 1F The main invention is improved or modified in that the commutator valve 17 comprises an "insert" with ports 21 communicating with respective working chambers 14 and co-operating with coaxially disposed ports 18, 19, which communicate with inlet and outlet ports 15, 16, respectively. Auxiliary ducts 32 may be formed at each end of the wheel 11. Alternatively, either form of the auxiliary ducts described in the parent Specification 1395817 may be incorporated. The insert may comprise first and second parts 15, 16 lodged in the wheel so as to revolve in a planetary manner therewith. The ports 21 may be displaced 90 degrees relative to the chambers 14, as shown.
