Abstract

483,929. Rotary engines. LANGLEY, T. W., and TECALEMIT, Ltd. Nov. 10, 1936, No. 30723. [Class 110 (ii)] The engine or pump is provided with a number of impellers 1 rotating about spaced axes in the same direction. Each impeller is constructed in accordance with the following formulµ wherein D =overall length of the impeller, r=radius of curvature of each end of impeller, M=distance between the centres of the radii of curvature of the ends of the impeller, R = radius of curvature of the side walls of the impeller, W=greatest width of impeller. A small clearance may be provided between the impeller tips and the casing. External gears couple the impeller shafts. A flexible coupling may be embodied. The inlets to the working spaces are coupled together, as are the outlets. An inlet 27, Fig. 3, leads to branches 26, 28, in a pump end cover. The opposite ends of the branches connect through passages 29, 30, with an outlet 31. A disc valve 36 co-operates with a seating 37 and the end of a seat 32. A further disc valve 38 is provided, and similar valves 41, 42, arranged in the branch 28. A passage 43 communicates between the central pumping space 21 and the passage 28. Spring- pressed abutments may bear on the impellers, or spring-pressed packing pieces may be arranged within the impeller tips. It is also stated that the impellers need not be equal in size. The pumps or engines may be provided in sets coupled together. In a modification, rotary sleeve-valves are driven by a central shaft, to control inlet and outlet ports.
