Ingxenye esetshenziselwa ukukhulisa umfutho kawoyela nokuqinisekisa inani elithile lamafutha, ukuphoqa uwoyela endaweni ngayinye yokungqubuzana. Uhlobo lwegiya kanye nephampu kawoyela yohlobo lwe-rotor zisetshenziswa kakhulu ezinjinini ezivuthayo zangaphakathi. Iphampu kawoyela yohlobo lwegiya inezinzuzo zesakhiwo esilula, ukucubungula okulula, ukusebenza okuthembekile, impilo ende yesevisi, ingcindezi kawoyela wephampu ephezulu, ukwakheka kwe-rotor pump rotor esetshenziswa kabanzi kuyinkimbinkimbi, ukucindezela kwe-powder metallurgy okunezinjongo eziningi. Le futha inezinzuzo ezifanayo zephampu yegiya, kodwa isakhiwo esihlangene, usayizi omncane
Ukusebenza okushelelayo, umsindo ophansi. I-Cycloid rotor futha amazinyo e-rotor yangaphakathi nangaphandle izinyo elilodwa kuphela, lapho benza ukunyakaza okuhlobene, ijubane lokushelela lendawo yezinyo lincane, iphuzu le-meshing lihlala lihamba ngephrofayili yamazinyo ye-rotor yangaphakathi nangaphandle, ngakho-ke, i-rotor yezinyo ezimbili zigqoka ezincane. Ngenxa yokuthi i-Engle yemvilophu yegumbi lokudonsa uwoyela kanye negumbi lokukhipha uwoyela likhulu, lisondele ku-145 °, isikhathi sokudonsa uwoyela kanye nesikhathi sokukhipha uwoyela sanele, ngakho-ke, ukugeleza kwamafutha kuzinzile, ukunyakaza kuzinzile, futhi umsindo uphansi kakhulu kunepompo yegiya.
