Injector ikalowetsedwa pamutu wa silinda, mphete ya O-mphete mu mphete zitatu za O imalekanitsa njira yamafuta mumutu wa silinda munjira yolowera mafuta ndi njira yobwerera mafuta (gawo lakumtunda ndi njira yobwerera mafuta). Chifukwa kupanikizika kwa mafuta panjira yolowera mafuta ndikwambiri kuposa njira yobwerera mafuta, pomwe O-ring yapakati ikasweka, mafuta omwe ali munjira yolowera mafuta amadumphira munjira yobwerera mafuta, motero amawonjezera kupanikizika kwamafuta. ndime yobwerera. Kuyimitsa kukazimitsidwa, kukakamiza munjira yamafuta obwerera kudzasinthidwa kupita kumalo olowera mafuta, kotero kuti kuthamanga kwamafuta pamaso pa dzenje la jekeseni sikungathe kuchepetsedwa panthawi yake kuti kuyatsa kwamafuta, zomwe zimapangitsa kuti moto uzivuta. . Kuopsa kwa kuwonongeka kwa O-ring kumasiyanasiyana ndi nthawi yayitali komanso yochepa ya moto. Cholakwacho chikachitika, zimakhala zovuta kudziwa kuti jekeseni yapakati ya O-ring ya jekeseni yawonongeka, ndipo m'pofunika kuti pang'onopang'ono mutulutse jekeseni kuti muyang'ane mpaka chifukwa chake chikupezeka. Mukasintha mphete ya O-yowonongeka, mphete ya O iyenera kuyikidwa bwino mu jekeseni wa jekeseni ndipo sichikhoza kupindika; Ayenera yokutidwa ndi mafuta pamaso potsegula yamphamvu mutu; Popeza jekeseni imatulutsidwa ndikulowetsedwanso, kawirikawiri, ngati palibe muyeso wotetezeka kwambiri, jekeseni ya plunger ya jekeseni iyenera kusinthidwanso.
