ABSTRACT:
A rotary piston internal combustion engine of trochoidal type of construction having a housing that consists of dual-curvature mantle runway and side parts, such housing having an eccentric shaft passing therethrough as well as having a triangular piston upon an eccentric of the eccentric shaft, such triangular piston having sealing parts rotating in continuous sliding engagement along a mantle runway in a planetary movement wherein the eccentric shaft is made hollow. The eccentric shaft is produced in a hydraulic pressure procedure. The eccentric shaft is lengthened and extended at an open end thereof via a pipe or tube pressed in the open end and coaxial therewith so as to extend beyond the shaft bearing or receiving of circulating pumps as well as output gears for additional auxiliary devices employable therewith. An end of the eccentric shaft extending beyond the shaft bearing has openings for inlet and discharge of fluid or liquid cooling medium.
