ABSTRACT:
This invention provides a package-type oil-cooled air compressor in which the housing is divided into two chambers, in one of which, a first chamber, are located the compressor unit, motor used to drive the compressor unit, air intake filter and intake regulator valve connected to the compressor unit, and in the other of which, a second chamber, are located the oil cooler and sirocco fan. An air duct connects the two chambers. Air outlets are formed in each of the chambers and an air inlet is formed in the second chamber. Air is introduced through the rotation of the sirocco fan into the second chamber via the air inlet. A portion of this air is directed into the first chamber via the air duct where a part is used to supply the compressor unit and the remainder flows over the components located in the first chamber to cool them and leaves via the outlet formed in the first chamber. The air that is not directed into the first chamber via the duct leaves the outlet formed in the second chamber after flowing over the oil cooler.
