Abstract

1324688 Diaphragm seals PHILIPS GLOEILAMPENFABKIEKEN NV and MASCHINENFABRIK AUGSBERG-NURNBERG AG 10 Aug 1970 [13 Aug 1969] 38388/70 Heading F2B A seal between a rod 4 and an element 2 (e.g. a piston rod and a displacer rod of a hot-gas reciprocating engine) comprises a centring sleeve 13 which engages the rod in two places 14, 15 and is accommodated in the element so as to be movable in the radial direction only relative to the element, a rolling diaphragm 16 between the sleeve and the rod and a sealing member 20, which may also be a rolling diaphragm, between the sleeve and the element. The diaphragms separate a gas space from a liquid space and the pressure differential across the diaphragms are controlled by a spring-load device 27. The gas spaces 23, 25 above the diaphragm are interconnected by an aperture 26 and the liquid spaces below the diaphragms are inter-connected by an aperture 22 and supplied with liquid through a ring 17.
