Denne oppgaven handler om å utforske mulighetene for å fjerne luft fra et hydraulikksystem mens det er i drift. Undersøkelser av dagens løsninger viser at det er mange måter å gjøre dette på. I hovedsak er det syklonprinsippet som grundig undersøkes i denne oppgaven. Med prototypetesting for effekt og utforming vises de ulike problemstillingene veldig tydelig og en drøfter hva som kunne gjøres for å bedre utluftningen ytterliggere. Videre er det også konstruert et hydraulisk aggregat som tar seg nytte av prinsipp for å redusere størrelsen på oljetanken. Det største fokuset i oppgaven er å få dette så kompakt som mulig for å spare både plass, olje, vekt, penger og miljøet. Dagens løsning som tar ca. 6,3 kubikkmeter ser ut til å da kunne erstattes med oppgavens løsning som er på omtrent 2,8 kubikkmeter uten å trykk-sette tanken.
This thesis is about exploring the possibilities for removing air from a hydraulic system while it is operational. Investigation of current solutions show multiple principles for doing this. This thesis focuses on using the cyclone principle for extracting air from the oil. With multiple prototype tests for shape and efficiency, the challenges with this solution become obvious. To complete the thesis a hydraulic power unit is constructed while using other principles to reduce the size of the tank. This reduction should lead to savings in space, oil usage, weight, money and the environment. The solution which is presented in this thesis is about half of the physical volume of normal units. This reduction is also done without pressurizing the tank.
