Abstract
Det er beskrevet et styreventl l system (10) som føler trykk l strømmende fluider og er beregnet for anvend- else på utblåsnlngsslkrlnger og er utstyrt med en drlvsyllnder (11) samt et stempel (12) for lukning av utblåsnlngssikrlngen der drlvsyllnderen (11) og stempelet (12) har en lukkende elde (14) og en åpnende side (16), og der lukkeslden har et effektivt areal som er sterre enn åpningssiden. Systemet (10) Innbefatter en føleanordning (35) som registrerer fallende trykk l den fluldumstrøra som blir rettet mot den lukkende side (14) l forhold til økninger l hastigheten på fluldum- strømmen. Et fluldum-retursystem er Innbefattet for valgvls dirigering av fluidet fra åpningssiden (16) av drlvstempelet til stempelets (12) lukkeslde (14) når trykkfallet over foleanordnlngen (35) antar en verdi som er over en på forhånd bestemt verdi for å redusere kravene til fluldumkapasltet og for som et alternativ å dirigere strømmen fra lukkeslden (14) til et utløps- punkt (23) når trykkfallet avtar under den på forhånd bestemte verdi. En sekvensventll (60) for valgvls foring av strømmen til føleanordnlngen (35) til bruk l kombinasjonen mellom føleanordnlngen (35) og fluldurn- retursystemet er også beskrevet.
