This invention relates to an improvement in a housing formation for a rotary piston machine of trochoidal construction with an outer envelope curve and a housing corresponding to said outer envelope curve, said piston being patterned after a turning point-free trochoid n:1, and working chambers between said housing and said piston separated by radial seals in said housing, THE IMPROVEMENT COMPRISING THAT THE HOUSING HAS THE FORM OF AN OUTER PARALLEL CURVE TO THE PISTON CONTOUR, WHEREBY THE EQUIDISTANT DISTANCE OF SAID PARALLEL CURVE CORRESPONDS AT LEAST TO THE GREATEST DEVIATION BETWEEN SAID PISTON CONTOUR AND THE COORDINATED EXACT OUTER ENVELOPE CURVE.
