Definitions
- the present invention relates to a turbine with a turbine wheel, as used for example as a drive for active oil separator, and a liquid separator with such a turbine.
- a separator In such active oil separators often a separator is used, which is rotated to ensure a sufficient degree of separation of a liquid from a gas, such as oil mist or oil droplets from blow-by gases of an internal combustion engine.
- Such turbines have a turbine wheel which is driven by a fluidic drive means.
- oil separators in ventilation systems of internal combustion engines especially in vehicles, the oil pressure of the engine oil is often used to drive the turbine wheel. But even with stationary oil separators, a hydraulic drive can be used to come.
- Such a turbine wheel is coupled to a shaft or mounted centrally on a shaft and drives this shaft, which in turn is coupled to a rotatable separating element.
- the drive fluid is guided through a center hole in the shaft to the turbine wheel where it is introduced into the turbine wheel.
- the turbine wheel has at its edge an approximately tangentially directed nozzle, over which the fluidic drive means is ejected. This will set the turbine wheel in rotation. Typical are speeds up to 20,000 rpm.
- turbine wheel is not limited to an approximately circular element, but also includes other forms of rotatable body.
- Such turbine wheels in the prior art are usually made of stainless steel. This makes the turbine wheel heavy and in particular costly and expensive to manufacture.
- Object of the present invention is therefore to provide a turbine wheel and a liquid separator available, which can be produced inexpensively, with stable outer contour and precise and have a low weight.
- the complexity of production is to be reduced, the integration potential increased and the assembly of the turbine according to the invention simplified.
- a liquid separator is to be provided which has such a turbine according to the invention.
- the turbine now has a turbine wheel, which has a first channel extending along the axis of rotation of the turbine wheel.
- This first channel can either serve as a central receptacle of a shaft, so that the shaft can be fastened to the turbine wheel, or extend in extension of the reception of such a shaft.
- the turbine can be sprayed onto a shaft, which is usually at least off. Sectionally made of steel.
- a bearing for the shaft can be provided in this area.
- the turbine wheel according to the invention further comprises a second passage extending substantially in the radial direction for guiding the fluidic drive means, for example engine oil, with an inlet and an outlet for the fluidic drive means.
- the inlet is in fluid communication with the first channel.
- the outlet is directed substantially in a tangential direction of the turbine wheel. In some cases, however, it may be advantageous if the exit direction is at an angle of 85-95 ° to the direction of the first channel, i. has a small vector component in the axial direction of the shaft. This is especially true at very high speeds.
- the turbine wheel according to the invention has exactly one second channel, since thus the entire drive fluid is available to the outlet of this one second channel.
- the turbine according to the invention furthermore has a fluid nozzle in the outlet.
- a single fluid nozzle but also a plurality of fluid nozzles may be arranged side by side, all of which have substantially the same outlet direction. Regardless of the exact number of nozzles results in a fluid guide, which is symmetrical at most, with respect to a cross section through the center plane of the turbine, but otherwise asymmetric.

It is also possible to make this fluid nozzle as an insert which is fixed in the outlet. This can be this
- Fluid nozzle inserted into the outlet and secured with a captive.
- a captive used for this purpose, for example, transversely to the longitudinal direction of the channel used swords or slides in question.
- the outlet may be conical.
- the fluid nozzle may be arranged in the outlet such that an exit direction of the fluidic drive means extends from the fluid nozzle substantially perpendicular to the first and / or second channel.
- the fluid nozzle may contain or consist of a metal, a ceramic or a high-quality plastic.
- the wall of the first channel and / or the second channel may completely comprise a metal reinforcement.
- the metal reinforcement forms the inner wall of at least one channel or nozzle. This allows a particularly simple production. In addition, less abrasion occurs on a metallic inner wall than on a plastic inner wall.
- the metal reinforcement of the first and / or second channel is formed as a metal tube, which is surrounded by a plastic at least partially, in particular encapsulated.
- the metal reinforcement or the metal pipe in the first channel in a connection region with the second channel has a recess into which the metal reinforcement or the metal pipe for the second channel is inserted and / or in which the metal reinforcement or the metal pipe for the second channel with the metal reinforcement or the metal tube in the first channel in particular media-tight welded, soldered or crimped.
- the metal reinforcements or the metal tubes for the first and second channel can also be welded, soldered, crimped or optionally inserted with the aid of O-rings or similar sealing elements even before the production of the turbine wheel.
- the turbine wheel can then be subsequently sprayed onto the bonded metal reinforcements or metal tubes.
- the metal reinforcements or metal tubes may also initially only be aligned and fixed in accordance with each other and then together in the material of the turbine wheel, such as. Plastic, to be embedded.
- the first and the second channel extend substantially rectilinearly.
- This is particularly advantageous in the production of the turbine wheel in the injection molding, injection compression and / or pre ssvon.
- a multiplicity of additional functions can easily be integrated into the turbine wheel according to the invention.
- This nozzle can be made in one piece with the turbine wheel, in particular be injected in one piece.
- connection piece on the top and / or bottom side of the turbine wheel, which makes it possible to mount the rotating components or at least partially receives and / or guides the shaft.
- a partition wall in particular a partition wall made integral with the turbine is provided so that no drive oil can reach the shaft. If such a partition wall is provided, the first channel is then in particular not designed to receive the shaft, but runs in extension of the shaft.
- the drive oil is supplied through a conduit section in the nozzle to the first channel and further to the second channel.
- the turbine wheel can be manufactured in lightweight construction.
- Thermoplastics include polyphenylene sulfide (PPS), polyetherimide (PEI), polyimides (PI), polyphthalamide (PPA), polyetheretherketone (PEEK), polyamide (PA), polypropylene (PP), polyamideimide (PAI), polysulfone (PSU) and / or Liquid Crystal Polymer (LCP) or combinations of the aforementioned materials particularly advantageous.

- UP polyester resins
- VE vinyl ester resins
- EP epoxy resins
- PF phenolic resins
- MF melamine-formaldehyde resins
- Such a turbine wheel can be produced particularly simply, for example by means of injection molding, injection compression molding or in a pressing process. If the turbine wheel is made of a thermoset material, this can also be done by means of transfer molding be accomplished.
- metals preferably light metals, for example aluminum.
- sintered material can be processed by means of 3-D printing.
- the second channel such that it passes from one peripheral edge to the other peripheral edge of the turbine wheel and thus has two opposite openings at the peripheral edge of the turbine wheel.
- the opening on one side of the channel which is not required for the fluid guide can then be closed with a closure means.
- a closure means are, for example, plugs that are pressed in the opening, can be secured with a sword or a slider. It is advantageous if the sword or the slide is introduced from or through the top or bottom of the turbine and at least partially guided in a groove laterally and / or in the opposite side of the insertion side.
- Such a sword or such a slide may also be part of another component adjacent to the turbine or formed as an integral extension of such.
- a welding of the plug is possible, this can possibly be combined with other welding operations for the production of the turbine.
- a screw cap, a bayonet catch or a press-fitted ball can serve to close an opening of the channel.
- This closure should advantageously be fluid tight so as to provide a closed fluid path from the inlet to the outlet.
- the closure means can be combined with a suitable sealing agent, such as an O-ring or a liquid sealant.
- the turbine wheel may be formed from a plurality of parts, in particular from two half shells.

- the two half-shells must by no means be identical or mirror-inverted.
- a half-shell is only a flat lid which closes an opening in the other half-shell.
- Half shells of the turbine can advantageously a seal, such as a rubber seal and / or an O-ring can be arranged. This is pressed between the two parts, for example by screwing, welding, clipping, gluing, bonding or otherwise bonding the two half-shells together, for example analogously to one
- the turbine wheel can furthermore have a housing, within which inter alia the channels (or their walls) and further stiffening structures, for example stiffening webs or stiffening ribs, can be arranged.
- the housing can be formed integrally with the turbine wheel. It is also possible to dispense with the housing and to produce the turbine wheel exclusively from the walls of the channels and possibly such stiffening structures.
- the outer walls of the channels, the stiffening structures and the housing all serve, among other things, also to stiffen the turbine wheel, to set the correct weight distribution (balancing of the turbine wheel) and, for example, also to guide the oil. Housing, stiffening structures and channels or their walls can consequently be interpreted differently depending on the design with respect to their position, their thickness and shape and the like.
- the configuration of the stiffening ribs or stiffening ribs may be for the design of noise, vibration and heat distribution (NVH, i.e. noise vibration harshness optimization).
- NVH noise vibration harshness optimization
- a ribbed structure promotes agglomeration and drainage of oil, especially sprayed oil.
- the housing may also be formed as a half-shell, for example as a bottom or lid (lower part and also as upper part) of the turbine wheel.
- the housing can advantageously have a smooth and / or closed surface.
- functional components for example an impeller for generating negative pressure and / or a sealing element.
- a turbine wheel made of plastic or substantially of plastic other functional elements such as a magnet can be embedded in the turbine wheel.
- a plain bearing can be poured into the turbine wheel, so that the turbine wheel can be stored together in common or separately from the shaft friction in an oil separator.
- the use of plastic also makes it possible to inject the turbine wheel directly on the shaft, for example, to spray media-tight on a steel shaft. Additionally or alternatively, a seal by means of additional sealing elements such as O-rings is possible.
