I-air compressor ethule engenawo uwoyela ingeyesicindezelo esincane se-piston compressor. Umgomo wayo osebenzayo ukuthi lapho imoto ishayela i-compressor crankshaft ukuze ijikeleze, ngokudluliswa kwenduku yokuxhuma, i-piston ene-self lubrication ngaphandle kokungeza i-lubricant izokwenza ukunyakaza okubuyisanayo, futhi ivolumu yokusebenza yenziwe ngodonga lwangaphakathi lwesilinda, ikhanda lesilinda nendawo ephezulu ye-piston izoshintsha ngezikhathi ezithile. Lapho i-piston ye-piston compressor iqala ukusuka ekhanda lesilinda, ivolumu yokusebenza kusilinda iyanda kancane kancane. Ngalesi sikhathi, igesi iphusha i-valve yokufaka eceleni kwepayipi lokungena bese ingena kwisilinda kuze kube yilapho ivolumu yokusebenza ifinyelela okuphezulu, futhi i-valve yokufaka ivaliwe; Lapho i-piston ye-piston compressor ihamba iye kolunye uhlangothi, ivolumu yokusebenza ku-cylinder iyancipha futhi umfutho wegesi uyanda. Lapho ingcindezi esesilinda ifika futhi ingaphezulu kancane kwengcindezi ye-exhaust, i-valve yokukhipha iyavula bese igesi ikhishwa kusilinda kuze kube yilapho ipiston idlulela endaweni enomkhawulo, futhi i-valve yokukhipha iyavalwa. Lapho i-piston ye-piston compressor ihamba kolunye uhlangothi futhi, inqubo engenhla iyaphinda. Okusho ukuthi, i-crankshaft ye-piston compressor ijikeleza kanye, i-piston iphinda ibuye kanye, futhi inqubo yokudla, ukucindezela kanye nokukhipha kutholakala ngokulandelana ku-cylinder, okungukuthi, umjikelezo wokusebenza uqediwe. Umklamo wesakhiwo somgodi owodwa nesilinda esimbili wenza ukugeleza kwegesi kwe-compressor kuphindwe kabili kukasilinda owodwa ngejubane elithile elilinganisiwe, futhi kulawulwe kahle ekulawulweni kokudlidliza nangomsindo.
