Claim:
An oil discharge assembly ( 301 , 501 , 701 , 901 ) for a turbocharger ( 300 , 500 , 700 , 900 ) comprising: a thrust collar ( 324 , 524 , 724 , 924 ) being generally cylindrical and having a first radially outwardly extending wall and a second radially outwardly extending wall, the first and second radially outwardly extending walls being axially spaced such that a first annular channel is defined therebetween, the first radially outwardly extending wall having an annular flange that at least in part defines a second annular channel; a thrust bearing ( 340 , 540 , 740 , 940 ) having a radially inner end received in the first annular channel; and an insert ( 400 , 600 , 800 , 1000 ) having an inner axially extending lip with a distal end, wherein the distal end is received in the second annular channel, the inner axially extending lip defining an annular drainage channel, the insert ( 400 , 600 , 800 , 1000 ) annularly surrounding a portion of the thrust collar ( 324 , 524 , 724 , 924 ), the annular drainage channel being radially inward of a radially outermost portion of the second annular channel, wherein an oil collection chamber ( 440 , 640 , 840 , 1040 ) is defined at least in part by the drainage channel of the insert ( 400 , 600 , 800 , 1000 ), the annular flange of the thrust collar ( 324 , 524 , 724 , 924 ) and the thrust bearing ( 340 , 540 , 740 , 940 ), and wherein the oil collection chamber ( 440 , 640 , 840 , 1040 ) is in fluid communication with an oil release interface between the thrust collar ( 324 , 524 , 724 , 924 ) and the thrust bearing ( 340 , 540 , 740 , 940 ), whereby pressurized oil discharged from the oil release interface is directed towards a radially outer region of the oil collection chamber ( 440 , 640 , 840 , 1040 ) and is collected in the oil collection chamber ( 440 , 640 , 840 , 1040 ) for subsequent exhaust.
