Incazelo emfushane:
Ukugeleza kuvunyelwe ukudlula ohlangothini olulodwa (V1 kuya ku-C1 noma V2 kuya ku-C2), bese ivalvu ihlala ivaliwe (ihloliwe) kuzo zombili izinkomba ezingemuva (C1 kuya ku-V1 noma C2 kuya ku-V2) ukuze ibambe futhi ikhiye isilinda noma ezinye iziqalisi; ukugeleza okungemuva kungenzeka kuphela uma kusetshenziswa ingcindezi eyanele yomshayeli ku-V2 noma ku-V1, esebenza njengezimbobo zomshayeli ezixhumene, futhi i-piston yomshayeli iphakamisa i-poppet esihlalweni sayo inqobe ingcindezi yembobo yesilinda.
