Title:
ROTARY PISTON INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2010/089030
Kind Code:
A3
Abstract:
2.2 The invention relates to two piston pairs (Fig. 1.1), each on a piston disc (5), (6) and forming a recurring working position at top and bottom dead center (UT, OT). Chambers (26 – 29) are formed by means of two pintles (48) each at the end faces of the pistons and perpendicular and trapezoidal sealing elements, together with piston rings in the piston disc within an annular cylinder. The sealing elements of a piston are pressed against the sealing rings of the piston disc and the inner surface of the annular cylinder by at least one corrugated spring (175). While one piston pair stops during sensor-controlled ignition of the fuel-air mixture, the second piston pair is rotated further, together with the working shaft, about a crank angle of 90°/60°/36°, and all working cycles of a four-stroke engine are performed. After another 135°/120°/108°, a new work cycle occurs. The engine-starting process can be performed by sensors in a contact-less manner both by two external, conventional starters, using segments of a circle, and by two internal electronically commutated motors having magnetic discs and closed- and open-loop electronics.
