Chigawo chomwe chimagwiritsidwa ntchito kuonjezera kuthamanga kwa mafuta ndikuwonetsetsa kuchuluka kwa mafuta, kukakamiza mafuta pamtunda uliwonse. Mtundu wa giya ndi pampu yamafuta amtundu wa rotor amagwiritsidwa ntchito kwambiri mu injini zoyatsira mkati. Pampu yamafuta amtundu wa zida ili ndi ubwino wamapangidwe osavuta, kukonza kosavuta, kugwira ntchito kodalirika, moyo wautali wautumiki, kuthamanga kwamafuta apompopompo, mawonekedwe ogwiritsidwa ntchito kwambiri ndi rotor mpope rotor ndizovuta, kukakamiza kwamitundu yambiri ufa. Pampu iyi ili ndi zabwino zomwezo za mpope wa zida, koma mawonekedwe ophatikizika, kukula kochepa
Opaleshoni yosalala, phokoso lochepa. Cycloid rotor mpope mkati ndi kunja rotor mano amodzi okha, pamene kuchita wachibale zoyenda, kutsetsereka liwiro la pamwamba dzino ndi laling'ono, meshing mfundo nthawi zonse kusuntha pamodzi mkati ndi kunja rotor dzino mbiri, Choncho, awiri rotor dzino pamwamba kuvala wina ndi mzake yaing'ono. Chifukwa emvulopu Angle ya chipinda choyamwa mafuta ndi chipinda chotulutsira mafuta ndi chachikulu, pafupi ndi 145 °, nthawi yoyamwa mafuta ndi nthawi yotulutsa mafuta ndi yokwanira, choncho, kutuluka kwa mafuta kumakhala kokhazikika, kayendetsedwe kake kamakhala kokhazikika, ndipo phokoso ndilotsika kwambiri kuposa pampu ya gear.
