1. Phokoso lopangidwa ndi kugwedezeka kwamakina:Zigawo za valavu yochepetsera mpweya wa gasi zimatulutsa kugwedezeka kwamakina pamene madzi akuyenda.Kugwedezeka kwamakina kumatha kugawidwa m'mitundu iwiri:

1) Kugwedezeka kwafupipafupi kochepa.Kugwedezeka kwamtunduwu kumayambitsidwa ndi jet ndi kugwedezeka kwa sing'anga.Chifukwa chake ndi chakuti kuthamanga kwa valavu kumatuluka mofulumira kwambiri, kakonzedwe ka mapaipi ndi kosamveka, ndipo kulimba kwa mbali zosunthika za valve sikukwanira.

2) Kugwedezeka kwakukulu kwafupipafupi.Kugwedezeka kotereku kudzayambitsa resonance pamene ma frequency achilengedwe a valavu amagwirizana ndi ma frequency osangalatsa omwe amayamba chifukwa chakuyenda kwa sing'anga.Zimapangidwa ndi valavu yochepetsera kuthamanga kwa mpweya mkati mwamtundu wina wochepetsera, ndipo zinthu zikasintha pang'ono, phokoso lidzasintha.Chachikulu.Phokoso lamtunduwu la makina ogwedezeka siligwirizana ndi kuthamanga kwa sing'anga, ndipo makamaka chifukwa cha mapangidwe osayenera a valve yochepetsera mphamvu yokha.

2. Chifukwa cha phokoso la aerodynamic:Pamene compressible zamadzimadzi monga nthunzi akudutsa kupanikizika kuchepetsa gawo mu kuthamanga kuchepetsa valavu, phokoso opangidwa ndi makina mphamvu ya madzimadzi amasandulika mphamvu phokoso amatchedwa aerodynamic phokoso.Phokosoli ndiye phokoso lovutitsa kwambiri lomwe limapangitsa phokoso lalikulu la valve yochepetsera kuthamanga.Pali zifukwa ziwiri za phokosoli.Chimodzi chimayamba chifukwa cha chipwirikiti chamadzimadzi, ndipo china chimayamba chifukwa cha mafunde owopsa omwe amabwera chifukwa chamadzi omwe amafika pa liwiro lalikulu.Phokoso la aerodynamic silingathetsedwe kwathunthu, chifukwa valavu yochepetsera kuthamanga imayambitsa chipwirikiti chamadzimadzi pamene kuchepetsa kupanikizika sikungapeweke.

3. Phokoso lamphamvu zamadzimadzi:Phokoso lamphamvu la Fluid limapangidwa ndi chipwirikiti ndi kutuluka kwa vortex pambuyo poti madziwo adutsa padoko lopumira la valve yochepetsera kuthamanga.
