Abstract
In a screw compression apparatus in which shaft sealing members () isolate a bearing space () from a rotor chamber () and a lubricating fluid separating collector () separates the rotor lubricating fluid from the target gas discharged by the screw compressor (), rotor lubricating fluid separated by the lubricating fluid separating collector () is introduced into the rotor chamber () via a rotor lubricating flow channel (), and a bearing lubricating system () supplies a bearing lubricating fluid to the bearing space (). The bearing lubricating fluid flowing out from the bearing space () is cooled and returned to the bearing space (). A part of the target gas may be supplied to the shaft sealing members () at a location between carbon rings of the shaft sealing members.
