Abstract
A flow characteristic regulating electromagnetic flow coupler is disclosed as comprising a pump duct and a generator duct for connection in separate flow circuits containing electrically conductive fluid. Circuit means electrically connect the separate fluid in each of the pump and generator ducts for conducting electric current through the fluid in each of the pump and generator ducts transversely of the fluid flow therethrough. Means are provided for applying respectively first and second magnetic fields through the fluids of the generator and pump ducts transversely of the current and fluid flow therethrough, whereby the fluid driven through the generator duct forces the fluid to flow through the pump duct. Means are provided for setting the magnetic flux density of the first and second magnetic fields in the generator and pump ducts at different levels B1 and B2 respectively, whereby the flow characteristic of the forced fluid in the pump duct is greater than that flow characteristic of the drive fluid in the generator duct.
