Abstract: A vane rotary pneumatic pump where surface treatment is applied to a metal material portion facing a pump space (18). This prevents water from adhering on a metal surface, enabling rusting to be prevented even when air with high humidity flows into the pump space (18). A vane rotary pneumatic pump using plate-like vanes (12) made from a material having self-lubricating capability, wherein gaps are provided between a rotor (8) and a front plate (14) and between the rotor (8) and an end plate (16) so as to prevent contact sliding, and surface treatment using one of an alumite film, nickel-phosphorus plating film, and Teflon film or a combination of them is applied to the metal material portion facing the pump space (18).

Abstract: A ceramic helical rotor expander using a double-ended or tandem herringbone type rotor arrangement with bearing and seal assemblies remote from the hot gas inlets and especially capable of operating at an inlet temperature of above 1100.degree. C. The rotors are solid or hollow and bonded to hollow metal shafts, and mounted in a composite or simple prismatic casing. The rotors, casing and shafts are constructed from low expansivity materials. In the preferred embodiment the rotors are constructed of silicon nitride and the shafts constructed of an molybdenum alloy, with the metal shafts being supported in bearings and secured to synchronizing gears. The rotors and casing may be provided with coolant channels therein, and are constructed to eliminate the problem of end leakages at inlet temperature and pressure, and the need for high temperature bearings and seals.
