We merely men-tion this turbine, which never to have seen the light ofday, and whose efficiency was only very moderate. As will have been remarked, all of these machines utilize thepressure of the steam while working in tight compartmentsand turning at high velocities. The play of three one-thou-sandths of an inch can be obtained, but it will be difficult tomaintain it under working conditions, so that the leakage willgrow greater and greater and the utilization of the pressure ofthe steam will become more and more defective.
