Abstract
Stempelborings forvrengninger i en undergrunns sikkerhetsventil reduseres eller elimineres når ventilhus utsettes for høye arbeidstrykk. I en utførelse er et stempel anordnet i en hylse (24) som er anordnet i en stempelboring (16). Boringen kan forvrenges, men hylsen (24) inne i den vil ikke forvrenges til det punkt hvor tetningstrykk forsvinner rundt stemplet. I en annen løsningsmåte er en boring eller boringer (18, 20) anordnet i umiddelbar nærhet av stempelboringen (16), for å gjøre tappenden av forbindelsen for ventilhuset mer ensartet i området ved stempelboringen (16), slik at trykkbelastningen ikke resulterer i tilstrekkelig forvrengning av stempelboringen til å miste stemplets tettende relasjon i sin boring.
