Flywheel pump with radial rotor slits

摘要

The pump has a rotor with radially aligned slits receiving the pump's vanes. The rotor's ends adjoin sealing faces which have inlet and outlet openings associated with suction and pressure areas. At least one hydraulic resistance is provided to separate the two pressure areas. This can be formed by webs (9,13) which separate the pressure areas of the pump on the delivery side.
