Wing cell pump for pumping fluids in motor vehicles comprises a rotor, a lift curve ring, and wings pre-tensioned by spring elements forming an integral part of the rotor

摘要

Wing cell pump comprises a rotor (2), a lift curve ring (3), and a number of wings (4) pre-tensioned by spring elements (5) forming an integral part of the rotor. Preferred Features: The rotor is made of plastic and the spring elements are irremovably injected into the rotor. The spring elements are flexible tongues or flat spiral springs arranged on a ring (6). The spring elements are made of spring steel or plastic. The wings, lift curve ring, a lateral disk (7) and/or a pump housing (8) are made of plastic. The plastic is a duroplastic.
