Abstract

The compressor comprises: a crankcase () carrying a cylinder () and a bearing hub () having a first and a second end portions () and defining a radial bearing (), in which is housed a crankshaft (); and a connecting rod () coupled to a piston () housed in the cylinder () and having a larger eye () mounted in an eccentric end portion () of the crankshaft (). Each of said end portions () is defined by a bushing extension () affixed in the interior of the bearing hub () and having an end portion () projecting outwards from the bearing hub (), in order to be elastically and radially deformed when pressed by a confronting portion of the crankshaft (), which presents coaxiality deviation in relation to the axis (X) of the radial bearing ().
