<p>The rotor set has a rotor housing (1) with a medium inlet and a medium outlet, comprising an external rotor (2) and an inner rotor (3) made of an elastic material, particularly plastic or polymer material. The external rotor is a uniformly corrugated ring of constant wall thickness (s-1) with rounded recesses and convexities (8,12), which are spring elements acting in the linear elastic area.</p> |
