Abstract:
An elliptical rotary engine comprising:a) an elliptically housing assembly including: i) a substantially hollow block member with an interior wall defining an elliptical interior chamber including an air fuel intake port and a exhaust port; ii) a base member having an oil intake port, a coolant inlet port, a coolant outlet port and a cam-like elliptically shaped piston vane guide; iii) a head member including an oil intake port and a cam-like elliptical shaped piston vane guide having a centrally disposed power shaft recess; iv) means for fastening said head member and said base member to said block member; v) means for transporting coolant introduced from said coolant intake port throughout the internal structures of said base member and back to said coolant outlet port, said block member and said head member to provide thermal stability to said housing assembly during operation; vi) elliptical for sealing the surface contact points between said block member and said base member and between said block member and said head member; and vii) means for introducing a spark into said interior chamber of said blocks; b) a rotor assembly including: i) a substantially cylindrical rotor having a first end and a second end; ii) a power extending from said first end of said rotor; iii) a retaining shaft extending from said second end of said rotor; iv) a plurality of equidistantly spaced piston vane channels radially extending through the entire length of said rotor; v) a plurality of longitudinally disposed piston vanes having a first medially disposed end and a second peripheral end sized and configured similar to the piston vane channels so as to radially slide therein, said second end having concave properties; vi) a plurality of longitudinally disposed convex apex seals, each of the convex apex seals having a first convex side and a second convex side, wherein said first convex side has a curvilinear radius substantially similar to that of said second convex side of each said piston vane; and vii) means for lubricating and cooling the aforementioned components of said rotor assembly.
