Muviri wevharuvhu wetsono uye vharafu yetsono zvakare maviri echokwadi zvikamu zvakatsvakwa uye kufananidzwa. Kune maburi mana emhuno ane dhayamita ye0.35mm pamusoro wemuromo, akagoverwa zvakaenzana, uye kona yepfapfaidzo i150°. Kune flange pamusoro pechikamu chepamusoro chemuromo, iyo inotsikirirwa pamucheto wezasi weinjector muviri ne nut. Iyo ndege yekubatanidza pakati pemhuno nemuviri wejekiseni yakanyatso kuderedzwa kuchengetedza mafuta akasimba. Pane pini yekumisikidza mundege kumucheto kwekumusoro kwemhuno uye muviri wejekiseni kuti uve nechokwadi chekuti nzira mbiri dzemafuta dzinoenderana, uye nzira yemafuta inotungamira yakananga kukamuri yekuunganidza yekumanikidza yemuromo. Mugumo wezasi wevharuvhu refu yetsono ine tapered pamusoro, iyo iri pamusoro pechigaro chevharuvhu yetsono mune jekiseni remafuta. Pachigaro chevharuvhu ichi pane maburi mana ataurwa pamusoro apa. Iyo cylinder duku kumucheto wepamusoro wevhavha yetsono inopinzwa mugomba pamucheto wezasi we ejector tsvimbo. Kudzvinyirirwa kwechitubu kumucheto wepamusoro we ejector tsvimbo inotsikirira vharafu yetsono pachigaro chayo, ichivhara buri remuromo.

Kana pombi yejekiseni yemafuta ichidzvanya yakakwira-kudzvanya mafuta mukamuri yekuunganidza iri pazasi pemuromo wepombi kuburikidza nejoinhi yepombi uye yakatsvetwa mafuta sefa chinhu, kudzvanywa kwemafuta kunowedzera. Pamusana pekumanikidzwa kwemafuta pamusoro pekoni pamucheto wezasi wevhavha yetsono, simba re axial rinoumbwa, rinoedza kusimudza valve yetsono. Kana mafuta ehutsi achiwedzera kukunda simba remazambara resimba rinodzora chitubu, vharuvhu yetsono inosiya chigaro chevharuvhu uye mafuta anobaiwa mucylinder kubva kumaburi mana ejekiseni nekumhanya kukuru. Kana pombi yejekiseni yemafuta yamira kupa mafuta, kudzvanywa kwemafuta mujekiseni remafuta kunodonha, vharafu yetsono inodonha ichidzokera kuchigaro chevharuvhu pasi pechiito chekudzvanyirira chinodzora chitubu, uye jekiseni remafuta rinomira pakarepo.
