Spiralrotationskolbenmaschine und Verfahren zu ihrer Herstellung
摘要
A scroll blade of a scroll fluid machine is formed of eutectic graphite cast iron in whose structure the average value of the largest eutectic shell is not more than one fourth of the height of a lap of the scroll blade. The scroll blade material thus formed will facilitate increasing working precision and reducing the number of working steps.
