Micromotor and micropump

摘要

The invention concerns a micropump for the substantially continuous delivery of a mass flow, the micropump having a sleeve axis and an offset axis of rotation. An internal rotor meshes with an external rotor in a sleeve and at least one outlet-side pressure opening in a first end-face termination part. Both rotors have a dimension smaller than 10 mm. The invention further concerns a micromotor of similar construction in which the diameter of rotors and the casing are below 10 mm. The pump and motor are extremely miniaturized yet still permit a continuous flow with high feed pressure and high output.
