Abstract
Trykkstyrt avfyringsanordning for anvendelse i forbindelse ' med et rartransportert perforeringssystem. Avfyringsanordningen i er forbundet med en kabel, og nedfares til kontakt med det I rartransporterte perforeringsapparat som er innmontert i brønnen. ; Kabelen fjernes og trykk overfares til rarstrengens ringkanal. I Ved et forutbestemt trykk vil et bruddelement (15) knekkes, j hvorved avfyringsanordningen armeres. Et fjærelement (29) utaver en kraft mot en slagtennstift () og bevirker derved at fluid ledes fra et reservoar (45) , gjennom en stramningsbane og mot et stempel (43) som er fastgjort til slagtennstiften. Ved én utfarelsesform kan stramningsbanen innsnevres, for oppnåelse av j en tidsforsinkelse innen slagtennstiften utlases ved at kraften ! fra en fjær tvinger tennstiften inn i en perkusjonsavfyrings-! anordning, for å detonere denne og det tilkoplede perforerings-i apparat. Alternativt kan stramningsbanen utelates, for å oppnå momentan avfyring. Avlastingsdeler i form av tunger (42) på stempelet (43) forhindrer at fjærens lagrede energi overfares til bruddelementet. I tillegg er det innfart en låsekile (11) for å forebygge relativ bevegelse av bruddelementet og utvikling av torsjonskrefter i tilknytning til en slik dreiebevegelse.
