ABSTRACT:
A compressor comprises one or more stages each including an impeller mounted for rotation on a shaft and rotatable in an impeller housing. A transmission is drivingly connected to the shaft and a bearing is provided supporting the shaft. Lubrication means are provided for the bearing which provide a continuous lubricant seal around the shaft between the shaft and the bearing to prevent air leaking through the bearing. A chamber is located between the impeller housing and the bearing for collecting excess lubricant and has an outlet for draining lubricant.
