Abstract

En seismisk luftkanon omfatter et legeme (18), et hovedkammer (32), to porter (46, 48), flere luftpassasjer (90-94), en skyttel (12), en returanordning (14) og en avfyringsanordning (16). Hovedkammeret (32) befinner seg inne i legemet. De to porter (46, 48) er anord- net i hovedkammeret og ligger langs en felles akse (A). Luftpassasjene for- binder en høytrykksluftkilde med retur- anordningen (14), hovedkammeret (32) og avfyringsanordningen (16). Skyttelen (12) glir langs den felles akse mellom en åpen stilling i hvilken hovedkammeret (32) er åpent, og en lukket stilling i hvilken hovedkammeret er lukket. Retur- anordningen (14) forspenner skyttelen (12) mot den lukkede stilling. Avfy- ringsanordningen (16) bringer skyttelen (12) til å bevege seg fra den lukkede stilling til den åpne stilling, hvorved trykkluft frigjøres samtidig fra de to porter (46, 48) og i motsatte retninger.
