<p>A rotary internal combustion engine has an annular stator (S) and two annular rotors (R1 and R2) positioned on each side of stator (S) and co-planar therewith. The rotors are rotatable about an axis perpendicular to the planes of the rotors and stator and defined by shaft (SH). The rotors turn in mutually opposite directions of rotation indicated by arrows (X and Y). Each rotor includes a plurality of chambers (CH1 and CH2) being even in number with stepped transitions (TR) between adjacent chambers (CH1 and CH2). The transitions (TR) are defined by transversely sliding sections (TF) which may move from a position level with chamber (CH1) to a position level with chamber (CH2) (an intermediate position is shown). The stator (S) has a raised housing surface (HS) which sealingly engages the chamber (CH1) but which provides a free chamber space within the chamber (CH2). The stator includes sliding abutments (AB) which, during rotation, may slide in contact with the surface of chamber (CH2) to then travel onto the surface of the transition (TF), this being co-extensive therewith. The transition section (TF) then moves, by means not shown here, to be co-extensive with the surface of chamber (CH1) to allow the abutment (AB) to smoothly run onto the surface of this chamber.</p> |
