Fixed vane rotary abutment engine

A fixed vane rotary abutment engine, comprising

• (a) a stator containing a main cylindrical chamber having a first longitudinal axis and at least one second cylindrical chamber communicating with said main chamber and having a second longitudinal axis spaced from and parallel with said first longitudinal axis;
• (b) a main rotor coaxially arranged within said main chamber, said main rotor having an outer diameter less than a diameter of said main chamber to define an annular portion of said main chamber, said main rotor including a vane extending radially outwardly from an outer surface thereof to a location adjacent to an inner surface of said main chamber;
• (c) at least one abutment rotor coaxially arranged within said second chamber, said one abutment rotor having an outer diameter corresponding with a diameter of said second chamber, said one abutment rotor containing a recess in an outer surface thereof which extends parallel to said second longitudinal axis, said second longitudinal axis being spaced from said first longitudinal axis by a distance corresponding with the sum of the radii of said main and one abutment rotors, whereby a first combustion chamber is defined in a portion of said annular chamber between said vane and an area where outer surfaces of said main and one abutment rotors are adjacent;
• and
• (d) a mechanism for rotating said main and one abutment rotors in opposite directions within said main and second chambers, respectively, said one abutment rotor recess receiving said main rotor vane during each revolution of said main rotor.
