| abstract | 1480042 Rotary positive-displacement fluidmachines ERYX CORP 13 Feb 1976 [10 March 1975] 05738/76 Heading F1F In a feed-water pump for a boiler an annular working-chamber 12 contains pistons 18 fixed to a ring 14, which is rotated by a gear-wheel 22 meshing with gear teeth 16 formed on and between the pistons. Water enters the chamber 12 through a chamber 26 and ports 8 and is ejected through a conduit 30 with the assistance of a compressible fluid e.g. steam from the boiler, supplied through a conduit 32. The compressible fluid is discharged at differing pressures through ports 34, 38. The comparatively low-pressure fluid issuing from the ports 38 may be used to charge the chamber 26 and a housing 24 for the gear-wheel so as to obviate leakage of air into the working chamber. The pistons may be furnished with sealing rings 20. |
