Abstract
1284060 Volume-compensating devices INDUSTRIE PIRELLI SpA 24 May 1971 [23 May 1970] 16686/71 Heading F1P A volume-compensation apparatus 10 for oilfilled electric power cables comprises a pressure tank 12 divided into two completely oil-filled chambers 14, 16 by a bellows 20 and end-plate 28. Chamber 14 communicates through a port 22 with the cable and chamber 16 communicates through port 22a with a chamber 24 which receives oil expelled from chamber 16. Valve means 26, 26a serve to close ports 22, 22a when the volume of chamber 14 reaches a predetermined minimum and maximum respectively, thus preventing an excess pressure differential across the bellows. Valve means 26 has a plunger 46 biased away from a closure member 56 by spring 64, member 56 being biased from the base of valve body 48 by spring 60. Valve means 26a is identical. When the volume of chamber 14 reaches a minimum, end-plate 28 engages plunger 46 to close port 22. If seating is not complete plunger 46 moves on downwards to seal a part 68 thereof against a valve seat 66. When chamber 14 attains a maximum volume plate 28 engages plunger 46a to close port 22a. Chamber 24 is connected to a gas pressure vessel 38. There is also described an embodiment in which chamber 24 and vessel 38 are combined, Fig.2 (not shown).
