Chinhu chinoshandiswa kuwedzera kumanikidzwa kwemafuta uye kuona kuti mafuta aripo, zvichimanikidza mafuta kune imwe neimwe nzvimbo yekukweshana. Rudzi rwegiya uye pombi yemafuta yerudzi rwerotor zvinoshandiswa zvakanyanya mumainjini ekupisa mukati. Pombi yemafuta yerudzi rwegiya ine zvakanakira zvechimiro chiri nyore, kugadzirisa zviri nyore, kushanda kwakavimbika, hupenyu hurefu hwebasa, kumanikidzwa kwemafuta epombi yakakwira, pombi yerotor inoshandiswa zvakanyanya. Chimiro cherotor chakaoma, kudzvanya poda ine hunyanzvi hwakawanda. Pombi iyi ine zvakanakira zvakafanana zvepombi yegiya, asi chimiro chakaoma, saizi diki.
Kushanda zvakanaka, ruzha rwakaderera. Mazino eCycloid rotor pombi yemukati neyekunze yerotor ane zino rimwe chete, kana achifamba zvishoma nezvishoma, kumhanya kwekutsvedza kwepamusoro pezino kudiki, nzvimbo yekutsvedza inogara ichifamba pamwe chete neprofile yemazino erotor yemukati neyekunze, saka, pamusoro pemazino maviri erotor dzinopfekana diki. Nekuti Angle yekamuri yekusveta mafuta nekamuri yekuburitsa mafuta yakakura, iri pedyo ne145°, nguva yekusveta mafuta nekuburitsa mafuta yakakwana, saka, kuyerera kwemafuta kwakadzikama, kufamba kwakadzikama, uye ruzha rwakaderera zvakanyanya pane pombi yegiya.
