Kamora hore mochini oa ho khanna o qalisoe, e khanna crankhaft ea konteraka ho potoloha ka lebanta le likhutlo li tharo, le fetotsoeng piston ka mochini oa molamu oa molamu ho etsa motsamao o phetoang ka hara silindara. Ha piston e tloha sekoahelong ho ea theko, molumo oa silindara oa eketseha, khatello ea silindara e tlase ho feta khatello ea sepakapaka, 'me moea o kantle o kenella ka silindara ka sefaele le pompo ea ho hula; Kamora ho fihla setsing se ka tlase se shoeleng, piston e tloha lehlakoreng la shaft ho ea lehlakoreng le koahelang, valve ea ho hula e koetsoe, bophahamo ba silinda butle-butle boa fokotseha, moea o ka hara silindara o hatelloa mme khatello ea eketseha. Ha khatello e fihla boleng bo itseng, valve ea ho qeta e sutumetsoa, ​​'me moea o hatelletsoeng o kena ka tankeng ea polokelo ea moea ka phaephe. Ka tsela ena, konpresser e sebetsa ho potoloha le ho potoloha, e ntse e fetisetsa moea o petelitsoeng ka tankeng ea polokelo ea moea, 'me butle-butle e eketsa khatello ka tankeng, E le ho fumana moea o hlokehang o hlokehang.
