Xa isiguquli sibaleka, umoya ungena kwisilinda sokuqala esivela kwivelufa yokutsala ngokusebenzisa isihluzo sokuthulisa. Kwi-stroke yokunyanzeliswa, umthamo wegesi wokuqala uyancitshiswa kwaye uxinzelelo lwegesi luyakhula. Ngexesha lenkqubo yokukhupha, irhasi ecinezelekileyo ingena kwindawo epholileyo yokuphola ngokusebenzisa ivalve yokukhupha. Ngexesha lokutsalwa kwesibetho sepiston yesibini, irhasi epholileyo yindawo epholileyo yokungena ingena kwisilinda yesibini ngokusebenzisa ivalve yokufunxa yesibini. Ngexesha lokubetha koxinzelelo lwepiston yesibini, yenza ukuba igesi ecinezelekileyo ifikelele koxinzelelo olucacisiweyo. Ngena echibini ngevalufa yesekethe yokukhupha (okanye ngenisa ichibi emva kwento epholileyo).  

Ukuthintela ioyile yokuthambisa (okanye inkungu yeoyile) ekungeneni kwirhasi ecinezelweyo, uyilo lwecompressor ludiliza ngendlela yesiNtu, ukuze indawo esembindini yecompressor ivelise uxinzelelo lokuthintela ukuvela kweoyile ethambisayo. Ukuze kuqinisekiswe ubunyulu berhasi ecinezelekileyo.  

Umgangatho wegesi okhutshwe kwisiguquli esingenayo ioyile ubalasele, kwaye uyilo lomxholo weoyile ngu- ≤ 0.01ppm. Imveliso ixhotyiswe ngesixhobo sokuqala ukothula umthwalo. Ukuqala ukothula kugqityiwe ngokusebenza kwe-centrifugal ukothula kunye nolawulo lwevalve ngaphakathi kwesiguquli. Oko kukuthi, xa isiguquli siyekile, ukothula umthwalo we-centrifugal kunye nolawulo lwevalve. Ukukhupha irhasi yoxinzelelo oluphezulu kwisilinda yesibini, ukuze ufezekise injongo yokungabikho komthwalo okanye umthwalo omncinci xa uqala kwakhona. Ukuthembeka kwemveliso kuphuculwe.  

Xa iyunithi yecompressor ingavaliwe, iguqula ivolumu yegesi ngokwayo kwaye uxinzelelo lolawulo aluqhubeki nokunyuka. Ibizwa ngokuba yimveliso yomoya okanye ukothula rhoqo imveliso.  

Isixhobo esilawula umoya sisebenza ngokunxibelelana nesothululi esifakwe kwintloko yesilinda kunye nevalve elawulayo efakwe kwitanki yokugcina umoya ukulungelelanisa ivolumu yomoya. Xa uxinzelelo kwitanki lomoya lungaphaya kwexabiso elilinganisiweyo, uxinzelelo olulawula ivalve luyavula, kwaye uxinzelelo kwitanki lomoya lungena ekwehliseni kwintloko yesilinda. Uxinzelelo lunyanzela i-piston kunye ne-bottom plate ye-unloader ukuba iwele ngokuchasene ne-piston spring of the unloader. Intonga yokuqhagamshela kwipleyiti engezantsi ityhala ukuvula ipleyiti yevaluva yokutsala, ukuze igesi engenayo kwisilinda iphume ekuvulekeni kwesivingco sokufunxa, ngoko ke irhasi icinezelwe ayinakuveliswa. Xa uxinzelelo kwitanki yokugcina umoya lusezantsi kunomahluko woxinzelelo oluchazwe yivelufa elawula uxinzelelo, ivalve elawula uxinzelelo ivaliwe, i-unloader piston kunye neplate esezantsi zisetwa ngokutsha, ivalve yokufunxa ibuyela ekusebenzeni kwesiqhelo, kwaye isiguquli siyalayishwa kwakhona. Uxinzelelo kulawula ivelufa uye ukothula ummiselo uxinzelelo kunye ummiselo umahluko uxinzelelo. Ukothula uxinzelelo kukothula umthwalo; Uxinzelelo olwahlukileyo ngumahluko phakathi koxinzelelo lokothula kunye noxinzelelo xa isiguquli silayishwa kwakhona.
