Abstract

153,327. Schmied, W. Nov. 4, 1919, [Convention date]. Fixed-abutment types; cooling; packing; plant. -Comprises a rotary pump having at least two working chambers. Fig. 1 shows a stator 1 having three cylindrical bores 3, 4, 5, the bore 5 being of somewhat greater diameter and forming abutments for the rotor 2. Sliding vanes 10 are arranged in slots 9 tangential to a circle 8 and normal to the stator at the outlets 7. They are in contact with the stator under the action of centrifugal force, and their number is such that one at least always bears on each of the abutments 5 to ensure fluid tightness. In addition, spring- pressed members 11 may be provided for this purpose. Fig. 2 shows a form having a cooling sleeve 13, outside of which are channels 14, 15 in two different planes connecting the inlet opening 18 with the inlets 6, 6, of the chambers and the outlets 7, 7 of the chambers with the outlet 19. The form shown in Fig. 1 may be used as a double-stage pump by arranging the two chambers in series. If the second chamber is of smaller dimensions, the machine may be used as a twostage compressor. For higher pressures, two machines may be used, the first working in parallel and the second being a single-acting machine; this allows rotors of the same size to be used, and if coupled directly will both run at the most efficient speed. A cooling apparatus may be directly inserted between the machines.
