Emva kokuba umatshini wokuqhuba uqalisiwe, uqhuba icompressor crankshaft ukuba ijikelezise kwibhanti engunxantathu, ethi iguqulwe ibe yipiston ngendlela yecrank rod ukwenza intshukumo ephindaphindanayo kwicylinder.Xa i-piston isuka kwikhava ukuya kwi-shaft, umthamo we-cylinder uyanda, uxinzelelo kwi-cylinder luphantsi kunoxinzelelo lwe-atmospheric, kwaye umoya wangaphandle ungena kwi-cylinder nge-filter kunye ne-valve yokufunxa;Emva kokufikelela kwindawo esezantsi efileyo, i-piston ihamba ukusuka kwicala le-shaft ukuya kwicala le-cover, ivalve yokufunxa ivaliwe, umthamo we-cylinder uyancipha ngokuthe ngcembe, umoya kwi-cylinder ucinezelekile kwaye uxinzelelo luyanda.Xa uxinzelelo lufikelela kwixabiso elithile, i-valve yokukhupha ityhilwa ivuleke, kwaye umoya ocinezelweyo ungena kwitanki yokugcina umoya ngombhobho.Ngale ndlela, i-compressor isebenza ngokujikelezayo kwaye ijikeleze, ngokuqhubekayo ihambisa umoya ocinezelweyo kwitanki yokugcina umoya, kwaye ngokuthe ngcembe yandisa uxinzelelo kwitanki, ukuze ufumane umoya ofunekayo.
