ROTARY PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2000 - IPC

FIELD: mechanical engineering; self-propelled vehicles. SUBSTANCE: engine has cylindrical housing space. Rotor end faces are provided with cylindrical covers of diameter corresponding to outer diameter of rotor. Pistons are made in form of bow-shaped section blades of width corresponding to rotor thickness and are installed for turning in cylinder from plane corresponding to rotor surface to bottom of slot around locking pins directed along generatrix of rotor outer surface and fixed in corresponding holes in rotor cover walls. Blades are provided with guide pins arranged at a distance from locking pins in parallel with the latter. Guide pins are passed through crescent-shaped cuts in walls of rotor covers for reciprocating in cuts, their free ends being placed in guide grooves for free movement in grooves. Free ends of guide pins are furnished with rollers installed for rotation around pin axes. Radius of arc describing the profile of rotor outer surface corresponds to radius of arc describing the profile of piston outer surface. Clearance between inner surfaces of rotor covers, edges of cylinder spaces and piston surface and clearance between inner surface of engine housing and rotor outer surface is overlapped be seals. EFFECT: increased engine power output- to-and dimensional characteristics ratio and improved reliability of engine operation. 6 cl, 5 dwg
