ABSTRACT:
A spiral displacement machine has a displacer with a central disk and spiral vanes on both sides arranged to revolve eccentrically in a housing with spiral vanes to provide working chambers which rotate spirally. The beginning and end regions of the vanes are angularly offset so that the working chambers do not open or close simultaneously.
