Isimanzisi somoya esine-oyile engenasiphako sesomatshini ojikelezayo wokubuyisela umpu. Umgaqo-nkqubo wayo osebenzayo kukuba xa i-motor iqhuba i-crankhaft ye-compressor ukuba ijikeleze, ngokuhambisa intonga yokuqhagamshela, ipiston ene-lubrication yakho ngaphandle kokongeza i-lubricant iya kwenza intshukumo yokubuyisa, kunye nevolumu yokusebenza eyakhiwe ngodonga lwangaphakathi lwesilinda, Intloko yesilinda kunye nomphezulu wepiston uya kutshintsha amaxesha ngamaxesha. Xa i-piston ye-piston compressor iqala ukuhamba entloko yesilinda, umthamo osebenzayo kwisilinda uyanda ngokuthe chu. Ngeli xesha, irhasi ityhala ivalve yokungena ecaleni kombhobho wokungena kwaye ingene kwisilinda ide ivolumu yokusebenza ifikelele kwelona liphezulu, kwaye ivalve yokungena ivaliwe; Xa i-piston ye-piston compressor ihamba kwelinye icala, ivolumu yokusebenza kwisilinda iyancipha kwaye uxinzelelo lwegesi luyanda. Xa uxinzelelo kwisilinda lufikelela kwaye lungaphezulu kancinci kunoxinzelelo lweemoto, ivelufa yokukhupha iyavula kwaye irhasi ikhutshwe kwisilinda ide ipiston ihambele kwindawo yomda, kwaye ivelufa yokukhupha iyavala. Xa i-piston ye-piston compressor ihamba kwakhona, le nkqubo ingentla iyaphinda. Oko kukuthi, i-crankshaft ye-compressor ye-piston ijikeleza kube kanye, i-piston iphinda ibuye kube kanye, kwaye inkqubo yokutya, ucinezelo kunye nokudinwa kufezekiswa ngokulandelelana kwisilinda, okt umjikelo wokusebenza ugqityiwe. Uyilo lwesakhiwo se-shaft enye kunye nesilinda ephindwe kabini yenza ukuhamba kwegesi kwisiguquli kabini kweso silinda enye kwisantya esikalisiweyo, kwaye silawulwe kakuhle kukungcangcazela nasekulawuleni ingxolo.
