| 20130189142 | DELIVERY UNIT - A delivery unit is already known, which comprises a drive shaft and a rotor driven by the drive shaft. The rotor is rotatably arranged in a stator housing, wherein the rotor has a toothing on the end face of said rotor that is remote from the drive shaft, wherein said toothing meshes with a toothing constructed on the stator housing. The drive shaft comprises an oblique sliding plane interacting with the rotor and which is constructed on a shoulder of the drive shaft and allows the rotor to gyrate with the rotor axis thereof about the drive axis of the drive shaft. Work spaces are formed between the toothing of the rotor and the toothing of the stator housing, wherein said work spaces can be filled via an inlet and emptied via an outlet. In one embodiment the fluid is admitted axially and discharged radially, and in the other embodiment the fluid is admitted and discharged axially. For that purpose, control valves in the form of non-return valves are required. The non-return valves cause additional internal leakages, resulting in a reduction in the volumetric efficiency of the pump. The valves are additional parts, which are associated with additional costs and an increased risk of failure. In the delivery unit according to the invention the control valves can be dispensed with.

| 20100143173 | DUAL-PLATE SWASH PUMP - A swash-plate machine for pumping fluids uses dual swash plates in complementary or mirror-image orientation. The vibration that is generated as a reaction to forced nutatory motion imposed on a single swash plate is thereby largely cancelled. Rotated orientation of the divider plate position in one chamber with respect to the other (preferably 90 degrees difference) provides four outputs per revolution instead of the two available from both sides of a single swash plate. Improved bearings for the part-spherical swash plate base permits only oscillatory movement for that part and facilitate better sealing. | 06-10-2010 |
| 20110200474 | INTEGRATED PUMP FOR COMPRESSIBLE FLUIDS - A swash pump for compressible fluids uses sealing contacts made between the nutatable swash plate and the fixed cone plates to centre and locate the inner swash sphere which slides against two resiliently mounted ring seals only, minimising pump friction. A slanted end of a common drive shaft supporting and turned by the rotor of an integrated, variable speed motor causes nutation of the sphere. All bearings, especially axially slidable roller bearings inside the sphere, may settle in position with respect to the common shaft for least frictional loss. This pump is also adapted for pumping explosive gases. | 08-18-2011 |
| 20120294747 | Cycloid Rotor Engine - A rotary engine has a cycloid rotor and a sealing grid including a face seal that rotates with the rotor, and including other seals that do not rotate with the rotor. As the rotor rotates within a housing, the rotor, housing and seal grid form at least one working chamber between them, the chamber undergoing a change from initial volume V | 11-22-2012 |
| 20130011287 | PUMP OR TURBINE FOR INCOMPRESSIBLE FLUIDS - A rotatable drive shaft in the swash pump or turbine for liquids is supported by one bearing at each end. An integrated motor or dynamo uses the same two bearings. The compound first bearing supports a slanted section of the drive shaft placed inside the inner swash sphere, and transfers rotational power to the attached nutatable swash plate. The second bearing confines rotation of the drive shaft in a defined axis. Either one of the bearings is made to prevent axial movement of the drive shaft, preventing swash pump misalignment. A resilient drive, and an immersed pump are described. | 01-10-2013 |
