A rotor (A) for use with a rotary machine and a rotary machine (1010) incorporating such rotor are disclosed. The rotor includes a pair of parallel side surfaces and a curved perimeter surface formed between the parallel side surfaces and of a plurality of contiguous mutually tangential curved portions. The curved perimeter surface includes a major portion (JK) defining a first major arc (A1) and a first radius (R1), a minor portion (LM) defining a first minor arc (A2) and a second radius (R2), and a pair of similar intervening curved portions (e'L, Ke') extending tangentially between major and minor arcs and is formed of a second major arc and a second minor arc of predetermined radii (R, r). When the rotor is mounted for coplanar, non-touching, and same directional rotation with another rotor, the curved perimeter surface of the rotor is separated from that of the other rotor by a predetermined and fixed distance. |
