Abstract
A 1:1 ratio rotary piston machine, with an external axle, which operates with interengaging teeth. Each piston has two teeth which mesh with recesses of the counter piston. That entire flank of each tooth which trails in the direction of rotation is set back with respect to the cycloid described by the trailing corner of the pertaining recess of the counter piston. Each recess is deeper than the path of the corners of the intermeshing teeth.
