Abstract

947,383. Intermeshing screw pumps and motors. SVENSKA ROTOR MASKINER A.B. Jan. 15, 1960 [Jan. 15, 1959], No. 34707/60. Dividend out of 947,382. Heading F1F. A rotary motor or compressor of the intermeshing screw type is provided with injection nozzles 64 located on the high-pressure side of the intersecting bores of the machine and in two parallel rows disposed on each side of the line of intersection 50 of the intersecting bores. Additional injection nozzles may be disposed in the end wall of the casing, see Figs. 1, 3 and 4 (not shown). Liquid having cooling, scaling or lubricating properties is fed through the nozzles as desired. Specification 832,386 is referred to.
