ABSTRACT:
A journal bearing for rotatably supporting a turbomachinery shaft is supported by a housing which defines a sump chamber around the bearing. Means are provided to deliver a flow of lubricating fluid to the journal bearing and to sequentially or serially spray or impinge the lubricating fluid, after use for lubricating purposes, against the inner wall surface of the housing to thereby provide cooling for the bearing sump without increasing the flow of lubricating fluid beyond that required for bearing lubrication.
