Abstract
The invention relates to an electric fluid pump with a semi-axial construction, in which a motor housing part (9), situated at the pressure end, has a conduction device (42). The conduction device (42) allows an almost completely irrotational flow to be achieved so that the kinetic energy of the tangential component of the flow velocity is converted into pressure energy with negligible friction losses. This feature of the invention increases the efficiency of the fluid pump. The dimensions of the electric motor can therefore be reduced while maintaining the same delivery quantity.
