Kwagura valve nigice cyingenzi cya sisitemu yo gukonjesha, mubisanzwe yashyizwe hagati ya silinderi yo kubika amazi na moteri. Umuyoboro wagutse utuma firigo ikonjeshwa mubushyuhe buringaniye kandi umuvuduko mwinshi uhinduka umwuka mubi mubushyuhe buke hamwe numuvuduko muke ukoresheje imbaraga zayo, hanyuma firigo ikurura ubushyuhe mumashanyarazi kugirango igere kubikorwa bya firigo. Kwagura kwaguka kugenzura imigendekere ya valve binyuze mumihindagurikire yubushyuhe kumpera yumuyaga kugirango hirindwe ikoreshwa ryagace ka moteri hamwe nikintu cyo gukubita silinderi
Muri make, kwaguka valve igizwe numubiri, ubushyuhe bwo gupima ubushyuhe hamwe nuburinganire
Uburyo bwiza bwo gukora bwo kwagura valve bugomba kuba uguhindura gufungura mugihe nyacyo no kugenzura umuvuduko woguhindura hamwe no guhindura imitwaro ya moteri. Ariko mubyukuri, kubera hystereze yo guhererekanya ubushyuhe mu ibahasha yerekana ubushyuhe, igisubizo cya valve yagutse gihora igice cyakubiswe buhoro. Niba dushushanyije igishushanyo mbonera cyigihe cyo kwaguka, tuzasanga atari umurongo ucuramye, ahubwo ni umurongo wuzuye. Ubwiza bwa kwaguka valve bugaragarira muri amplitude yumuraba. Ninini ya amplitude, buhoro buhoro reaction ya valve nubuziranenge bwiza
