Ụkpụrụ na-arụ ọrụ nke compressor ikuku ogbi na-enweghị mmanụ: compressor ikuku na-enweghị mmanụ bụ obere piston compressor.Mgbe moto otu ogwe aka na-ebugharị crankshaft compressor ka ọ gbanwee, ọ na-eme onwe ya mmanye na-agbakwunyeghị mmanụ ọ bụla site na nnyefe nke mkpanaka njikọ.Piston na-emeghachi omume.Olu na-arụ ọrụ nke mgbidi dị n'ime nke cylinder ahụ, isi cylinder na elu elu nke piston ga-agbanwe kwa oge.

Mgbe piston nke piston compressor na-amalite ịkwaga site na isi cylinder, olu na-arụ ọrụ na cylinder na-eji nwayọọ nwayọọ na-abawanye → gas dị n'akụkụ ọkpọkọ oriri, na-agbanye valvụ oriri n'ime cylinder, ruo mgbe olu na-arụ ọrụ ruru oke, ihe oriri. ikuku Valve mechiri → Mgbe piston nke piston compressor na-agagharị na ntụgharị ntụgharị, olu na-arụ ọrụ na cylinder na-ebelata na nrụgide gas na-abawanye.Mgbe nrụgide dị na cylinder ahụ ruru ma dị ntakịrị elu karịa nrụgide nkwụsịtụ, valvụ ahụ na-emepe emepe na gas na-apụ na cylinder ruo mgbe piston na-emechi valvụ ahụ ruo mgbe ọ ruru njedebe.Mgbe piston nke piston compressor na-emegharị ọzọ na ntụgharị ihu, usoro dị n'elu na-emegharị onwe ya.

Ya bụ, crankshaft nke piston compressor na-atụgharị otu ugboro, piston na-akwụghachi otu ugboro, na oriri, mkpakọ, na ikpochapụ usoro na-aga nke ọma na-aghọta na cylinder, ya bụ, a na-arụ ọrụ okirikiri.Nhazi usoro ihe eji eme ihe na-eme ka ikuku compressor na-agbapụta okpukpu abụọ nke otu cylinder mgbe agbanyere ọsọ ọsọ, a na-achịkwa ya nke ọma na mkpọtụ na njikwa mkpọtụ.
