Abstract
This invention relates to an improvement in a rotary piston engine of trochoidal design, of the epitrochoidal or hypotrochoidal type with an outer envelope, with the piston surface and/or housing bore being equidistant to the mathematically exact trochoid, and including a follow-up drive, the improvement comprising that the minus-equidistant of the piston and/or of the housing bore has a value exceeding 10% of that of the generating radius and smaller that that for which the piston contour is tangent with the follow-up drive in the dead center positions.
