Integrated hydraulic energy converter for use as liquid pump and/or as electricity generator has impeller wheel and rotor forming integrated unit with liquid flow path through rotor

摘要

The device is able to operate as a liquid pump and/or as an electricity generator and contains an impeller wheel (5), a wheel housing, a diffuser (12), a rotating electrical machine with an armature attached to the housing and a rotor attached to the periphery of the impeller wheel and arranged to form a gap between the rotor and armature. The impeller wheel and rotor form an integrated unit with a liquid flow path through the rotor.
