Abstract
121,518. Ransomes & Rapier, and Cracknell, R. J. Dec. 19, 1917. Centrifugal and screw Sprengel pumps; leakagepreventing devices.-In a rotary pump in which a rotor B carrying a peripheral helical channel, rotates eccentrically in a casing M in which a liquid piston is maintained by centrifugal action, the channels are formed by parallel walls and are of two widths, each part of uniform width extending approximately completely round the rotor, and the wider channel D opening into the narrower G. Vanes Q assist the entry of the gas through openings M<2> to the wider channel D. The narrow channel G is made of less depth than the wider channel. The inlet J and outlet K of the channel may be in the cylindrical surface, as shown in Fig. 3, or in the outer wall as shown in Fig. 6. Liquid is maintained in the casing M at a constant level by a pump N causing a continuous flow through the pipe N' and an overflow opening M<4>. A liquid seal on the high-pressure chamber is provided by an annular channel O<1> on the rotor, which dips below the surface of the liquid piston at one point and into which dips the whole periphery of a fixed disk P.
