Abstract

939,779. Rotary internal combustion engines; liquid seals. F. ZIMMERN. Feb. 1, 1962 [Feb. 3, 1961], No. 3870/62. Classes 110 (2) and 122 (5). A rotary I.C. engine comprises coaxial multistart compressor and turbine screws 1, 7, Fig. 1, housed in a common casing 8, Fig. 8, and mounted on a common shaft 29 and each meshing with a pair of pinions 16, 15 respectively disposed in planes containing the shaft axis. Air admitted to the upper end of the casing is compressed by means of the screw 1 and the pinions 16 and passed to combustion chamber 9, Fig. 2, to which liquid fuel supplied by a pump 37 is continuously admitted through a pipe 11. The pump 37 is driven by the shaft 29 through worm and bevel gearing and a variable speed transmission 34. The gases of combustion pass into the threads of the screw 7 where they expand and rotate the screw. Pumps 35, 36 driven by the shaft 29 through the worm and bevel gearing and a variable speed transmission 33 circulate cooling and sealing liquid through the engine. The liquid enters the top of the casing 8 through inlets 47, 48 and forms a seal between the casing and the crests of the threads of-the screw 1. At the junction of the screw 1 with the screw 7 the liquid is thrown outwardly by centrifugal force and separated from the air, fins 4 directing the liquid outwardly and causing it to form a liquid ring 13. Liquid from this ring passes through grooves 6 to permit sealing of the space between the easing and the crests of the threads of the screw 7 and through ducts 14 to provide a liquid seal along the side of the pinion 15. To obtain a higher compression ratio the outer profile of the screw is made cylindrical instead of being generated by rotating a circular arc whose centre coincides with that of the pinions. Specification 923,042 is referred to.
