Abstract

1352576 Rotary positive-displacement machines C BANCROFT 19 April 1971 [9 April 1970] 26702/71 Heading F1F A compressed-gas motor, or pump, similar to that described in Specification 1270993 has sets of rotary mutually-oscillating pistons 61 .. 64 and pairs of endwalls 72, 88 and 74, 92 with axial pressure-loading chambers 99 therebetween pressurized by working fluid e.g. air, leaking from the spaces between the pistons. To minimize leakage across the piston edges a sealing ring 83 on each of the walls 72, 74 has projections 86 meshing with projections 80, and may comprise sectors 102 pressed apart by wedgelike plungers (103), Fig.4C (not shown).
