Abstract: A method and an ejection device are provided for discharging contaminants out of a seal chamber of a rotating-fluid machine driving a main flow of contaminated fluid. The ejection device incorporates an obstacle for arresting a portion of the flow in the seal chamber to stagnation pressure, whereby a zone of fluid at stagnation pressure is created. A discharge passage is disposed in the seal chamber adjacent to a region of concentration of contaminants and in the zone of stagnation pressure created by the obstacle, whereby contaminants are pumped out via the discharge passage into the main driven flow. The discharge passage is disposed upstream of the obstacle and provides fluid communication between the seal chamber and a process side of the machine. The method and the ejection device are operative with a machine driving fluid in clockwise direction, in counterclockwise direction, and in both clockwise and counterclockwise direction.
