Abstract

Gassregulatorsammenstilling som styrer trykket i gass fra et gassreservoar til en pneumatisk drevet anordning, innbefatter et primært hus som omgir et par av gassregulatorer. Gassregulatorene er innrettet på linje med hverandre i serie inne i det primære hus mellom et innløp som skal ta imot høytrykksgass, og et utløp som skal slippe ut gass med styrt trykk. Hver gassregulator innbefatter en tettbar ventil som angir en inngang og en utgang, hvor hver ventil innbefatter et stempel som har en sylinder og en stang. En fjær befinner seg i tilstøring til nevnte stempel for å tvinge nevnte stempelsylinder bort fra nevnte motsvarende innløp, og et mellomleggselement nærliggende nevnte fjær for å justere den kraft som blir påført nevnte stempelsylinder av nevnte fjær. Hver ventil 15 tillater gass å strømme gjennom den motsvarende gassregulator inntil et forhåndsbestemt trykk er oppnådd i det respektive utløp i den respektive gassregulator, på hvilket tidspunkt det forhåndsbestemte trykk vil stenge den motsvarende ventil.
