A pressure gas engine having an inner first member of circular cross section with a periphery containing first energy conversion means for converting gas pressure to power and an outer second member extending around the first member and with a generally circular inner surface facing the outer surface of the first member and having second energy conversion means in the inner surface facing the first member and for converting gas velocity to power. In certain embodiments the inner and outer arrangements of the first and second members will be reversed. At least one of these first and second members is rotatable about an axis of rotation by the force exerted thereon due to the gas acting on its energy conversion means with one of the energy conversion means in either the first member or the second member comprising at least one and preferably a plurality of spaced converging-diverging nozzles each lying on a chord of its member that is less than the diameter and exhausting toward the other energy conversion means with the other energy conversion means comprising a series of impulse turbine buckets facing the nozzles. Each bucket is inclined with respect to its member and is adapted to be aligned with the nozzle exhaust on relative movement of the first and second members with respect to each other. |
