Abstract

1396702 Rolling diaphragm seals GIRLING Ltd 25 Aug 1972 [27 Aug 1971] 40254/71 Heading F2T A rolling diaphragm for a servomotor has an axially-extending support or spacer member 36 freely located in the. open fold 30. The support 36 may be made of metal or plastics and formed as a continuous or segmental ring or formed from a piece of wire folded in wave-like manner into a cylindrical shape.
