<p>When as the dimensions of an inner rotor of a rotary pump utilizing the trochoidal curve, a diameter of a base circle is represented by A mm, a diameter of a rolling circle by B mm, a diameter of a rotary path by C mm, an eccentricity by e mm, an eccentricity ratio by fe = e/B, a ratio of rotary path by = C/B, a ratio of base circle by n = A/B, a minor diameter of inner rotor by d4, and the number of teeth of inner rotor by n1, and K0 = (A/B + 1) x | B - 2e | and k1 = (n + 1) x | 1 - 2fe are given, the inequality or equality: C/K0 </= fc/K1 </= 1.1 is satisfied. <??>The invention provides a rotor for a rotary pump which is at least substantially free from the generation of a duplicate portion or an edge portion. </p> |
