Abstract

Den foreliggende oppfinnelse tilveiebringer en sviktbeskyttelsesanordning som inkluderer en luftkilde som tilveiebringer luft som har et lufttrykk, en første ventil i fluidkommunikasjon med luftkilden, hvilken tillater fluidkommunikasjon av et styringsfluid mellom en første fluidport og en annen fluidport når lufttrykket er i det minste et minimum lufttrykk og hindrer fluidkommunikasjon av styringsfluidet mellom den første fluidport og den annen fluidport når lufttrykket er under minimum lufttrykket, en annen ventil i fluidkommunikasjon med luftkilden, hvilken hindrer kommunikasjon av luft mellom et luftinnløp og et luftutløp når lufttrykket er i det minste minimum lufttrykket og tillater kommunikasjon av luft mellom luftinnløpet og luftutløpet når lufttrykket er under minimum lufttrykket, en tredje ventil i fluidkommunikasjon med luftkilden, hvilken tillater kommunikasjon av luft til et tredje ventilutløp når lufttrykket er i det minste minimum lufttrykket og hindrer kommunikasjon av luft til det tredje ventilutløp når lufttrykket er under minimum lufttrykket, en trykkbeholder i fluidkommunikasjon med det tredje ventilutløp og som har et luftutløp, hvor luftutløpet er i fluidkommunikasjon med luftinnløpet til den annen ventil, og en varslingsinnretning i fluidkommunikasjon med luftutløpet fra den annen ventil og som er funksjonsdyktig til å sende ut lyd når luft kommuniseres fra luftutløpet.
