Description
CLAIMS 1. A fluid displacement pump having a drive shaft intended for driving a least a first and a second rotating pumping member by a driving means driving the drive shaft, said pump being provided with a coupling arrangement between the at least first and second pumping member, said at least first and second pumping member in total exhibiting a certain increased pumping capacity at a certain reduced rotational speed of the drive shaft. 2. A fluid displacement pump according to claim 1, where the coupling arrangement is a coupling capable of infinitely variably adjusting the rotational speed of the second pumping member independently on any change in the rotational speed of the drive shaft. 3. A fluid displacement pump according to claim 1, where the coupling arrangement is a coupling capable of stepwise adjusting the rotational speed of the second pumping member independently on any change in the rotational speed of the drive shaft. 4. A fluid displacement pump according to claim 1, where the coupling is provided by means of a singe shaft constituting an output shaft of the first pump and an input shaft of the second pump, said single shaft thereby being common to the two pumps. 5. A fluid displacement pump according to any of claims 1-4, where the driving means is an electrical driving means such as an electrical motor. 6. A fluid displacement pump according to any of claims 1-4, where the driving means is a mechanical driving means such as a gearbox. 7. A fluid displacement pump according to any of claims 1-4, where the driving means is a hydraulic driving means such as a hydraulic motor. 8. A fluid displacement pump according to any of claims 1-4, where the driving means is a main shaft of a rotor of a wind turbine. 9. A fluid displacement pump according to any of claims 1-8, where the at least first and second pumping member are capable of pumping the fluid independently on the rotational direction of the first and second pumping member. 10. Fluid displacement pump arrangement according to any of claims 1-9, characterised by said coupling comprises an epicyclic 3-way differential with one shaft connected to an output drive shaft of the first pumping member, one shaft connected to an input drive shaft of the second pumping member, and the third shaft connected to a speed-variable motor, for example an electrical motor or a hydraulic motor. 11. Fluid displacement pump according to any of claims 1-10, characterised by said coupling being a hydrostatic transmission from the output drive shaft of the first pump to the input drive shaft of the second pump. 12. Fluid displacement pump according to any of claims 1-10, characterised by said coupling being a hydrodynamic transmission from the output drive shaft of the first pump to the input drive shaft of the second pump. 13. Fluid displacement pump according to any of claims 1-10, characterised by said coupling being a mechanical coupling, a viscous coupling or electric coupling or a electromechanical coupling from the output drive shaft of the first pump to the input drive shaft of the second pump. 14. Fluid displacement pump according to any of claims 1-10, characterised by said coupling being based on electro-technical principles such as electromagnetic transmission or Eddie-current. 15. Fluid supply system comprising a fluid displacement pump according to any of claims 1-14, characterised by comprising an fluid inlet and a fluid outlet of the first pump and a fluid inlet and a fluid outlet of the second pump, the fluid outlet of the first pump leading only to a main fluid conduit, and the fluid outlet of the second pump leading both to the main fluid conduit and leading to a branch fluid conduit of the fluid system, said branch fluid conduit being provided with a control valve for controlling the flow of fluid through the branch fluid conduit in relation to the flow fluid to the main fluid conduit. 16. Fluid system according to claim 15, said branch fluid conduit leading to the inlet of the first pump. 17. Fluid system according to claim 15, said branch fluid conduit leading to a fluid reservoir. 18. Fluid system according to claim 15, said branch fluid conduit leading to the inlet of the second pump.
