Therefore durability of the supercharger should not be a problem though the same comment would not necessarily apply to the clutch. Fuel economies of the order of 13 relative to that of a naturally aspirated engine developing the same maximum power should be obtainable. Screw-type compressors The first screw-type compressor was developed by Krigar in 1878. In the early nineteen-forties two compressors of similar type were introduced for supercharging the internal combustion engine. One was the invention of A. J. R. Lysholm of Ljungstr0ms Angturbin Sweden and the other the unit produced by the Saurer company in Switzerland. In each spiral lobes on a male rotor meshed with grooves in a female rotor as shown in Figs and . The spiral on one rotor is left- and that on the other right-handed the two rotating in opposite directions. During the rotation air is drawn through the inlet port in one end of the casing where it enters the spaces between one after the other in turn the spiral grooves on the female and their meshing lobes on the male rotor. This is the induction phase of the cycle because the lobe that is beginning to uncover the port is also beginning to withdraw from its groove so the space between each meshing pair is increasing allowing the air at atmospheric pressure to enter. As rotation continues this air is carried around by the grooves in the female rotor until the inlet port is covered by its leading edge. This is the beginning of the compression phase because the lobe is beginning to mesh into the groove at the inlet end and .
