Abstract

Oppblåsbar pute (1) dannet av en blokk av elastisk deformer-bart materiale, omfattende en indre sliss (2) avgrenset av vegger som i den opprinnelige tilstand ligger mot hverandre slik at blokken har kompakt tverrsnitt, samt en oppblåsings-kanal (3) med en forste ende (3a) ved slissen og en andre ende '(3b) som er koblet til et forråd av fluid under trykk. Puten kan benyttes i en jekkanordning for forskyvning av et gjenget element, omfattende midler for å utove en stempelvirkning på et stempelelement, hvilke midler utgjøres av en pute i henhold til oppfinnelsen.Inflatable cushion (1) formed by a block of elastically deformable material, comprising an inner slot (2) delimited by walls which in the original state lie against each other so that the block has a compact cross-section, as well as an inflation channel (3) with a first end (3a) at the slot and a second end '(3b) connected to a supply of fluid under pressure. The pad can be used in a jacking device for displacing a threaded element, comprising means for exerting a piston effect on a piston element, which means are constituted by a pad according to the invention.
