Abstract

En drivanordning for hydroakustiske sendere omfatter. minst ett aktiverende element (1) som er innrettet til å utføre en frem- og tilbakegående bevegelse, hvor bevegelsen av det aktiverende element (1) omfatter en økning og en minskning av avstanden mellom to ender av det, og minst ett fjærorgan (5,27) som er forbundet med det aktiverende element (1) i endene og som rager i en krum linje mellom endene, idet økningen og minskningen av avstanden mellom endene resulterer i en forandring av fjærorganets (5,27) krumning og derved i en bevegelse av det.Anordningen omfatter et element (12,13,28) for forskyvning av en masse, idet dette forskyvningselement er forbundet med fjærorganet (5,27) slik at bevegelsen av det sistnevnte overføres til forskyvningselementet (12,13,28) og genererer en forskyvning av dette med nevnte masse-forskyvning som resultat. Oppfinnelsen vedrører også anvendelse av anordningen for transport av hydroakustiske. bølger i en væske.
