Improvements in Elastic Fluid Turbines.
Реферат: 12,184. Wilson, L. May 28. Steam &c. turbines.- A reversible parallelflow turbine driven by steam, compressed air, or other gaseous fluid is shown in Fig. 2. The vane wheels e are mounted on the shaft B<1> and have an outer ring of vanes e' for forward running and an inner ring F<3> for reversed running. Annular steam channels U with supply pipes G<1> and nozzles a correspond with the two rings of vanes, either of which can be closed at its discharge end by means of a ring valve L operated by screwed spindles and adjusting hand-wheels. The outer nozzles a, Fig. 5, are tapered and their outlets are controlled by cut away plug cocks c with pinions J on their outer ends gearing with an annular rack K operated by worm gearing n or by a governor. Both rings of vanes may be arranged to drive in the same direction. Each turbine wheel is surrounded by a grooved ring h so that condensation water is collected by the rings and removed by pipes i leading to steam traps.
