Description

The The invention relates to a vane machine with at least one wing connected to a shaft.

So far are vane machines in the form of the prior art of vane pumps known to have several wings exhibit. Two adjacent wings form a cell in which a medium is promoted. Usually wise such vane pumps a variety of cells to maximize throughput and the largest possible pressure to achieve. The disadvantage of these pumps, however, is that they have a need some speed, to achieve an acceptable throughput and high pressure. The higher However, the speed of these pumps is, the higher the running noise, the depending on the purpose of the pump can be disturbing.

The Invention has the task of the vane machine of the beginning mentioned type to improve that the running noise minimal are.

The Invention solves the task with a vane machine of the beginning mentioned type, according to the invention, the at least one wing during the Rotation of the shaft is perpendicular to the shaft reciprocable. Because the wing while the rotation at the same time and perpendicular to the shaft back and forth is, can the vane machine with only a few wings, in extreme cases even with only one single wing, so that their running noise even at high speeds are minimal.

The Shaft may have a slot in which the at least one wing hin- and is movable. Through the slot, the at least one wing on easy way to be attached to the shaft. At the same time leads the Slit the wing at his float during the rotation of the wave.

The Vane machine may have an elliptically formed chamber in which the at least a wing rotates. Due to the elliptical shape of the chamber is a through the Vane machine streaming Medium during the rotation of the at least one wing greatly accelerated. If the vane machine as a pump is used, then with it thus also at low speeds high pressures generated.

Around one possible at low speeds can generate high pressure, the shaft near an inlet and a Outlet between the inlet and the outlet to be arranged.

If the shaft on an inner wall of the chamber, advantageously between the inlet and the outlet, then the medium can not from a pressure side of the chamber overflow to a suction side of the chamber, so that with the working as a pump vane machine also at a low speed maximum pressure can be achieved.

The Shaft can have areas of different diameters where the one larger diameter having disposed portion of the shaft inside the chamber can.

By the arrangement of the thicker portion of the shaft within the chamber, needed Do not attach any other fasteners to the shaft against falling out from a housing the vane machine to secure.

Of the at least one wing can be as long as the small diameter of the chamber. Conveniently, can the at least one wing slight be smaller than the small diameter of the chamber to wear the chamber and of the grand piano to avoid.

Further the invention relates to a pump according to the invention a vane cell machine according to one of the claims 1 to 7 is.

Several Pumps can be driven by a common shaft, the pumps suck in and expel the medium with a time delay. On this way you can any pressure pulsations are compensated and the pumping capacity is increased.

advantageously, The pump can be a hydraulic pump, a gasoline pump, a water pump or the like. Thus, the pump can also be used for a hydraulic Power steering are used.

It also concerns the invention an internal combustion engine according to the invention a vane machine according to one of the claims 1 to 7 is.

Several Internal combustion engines can have a common drive shaft, wherein the individual intake and ignition phases delayed to each other. Thus, you can any speed fluctuations are compensated and the power is increased.

advantageously, The internal combustion engine can be a gasoline or diesel engine.

The invention also relates to a pump Direction according to the invention according to at least one pump according to one of claims 8 to 10 and / or at least one internal combustion engine according to one of claims 11 to 13.

Around one possible high and even performance to reach the at least one pump and the at least one internal combustion engine a have common shaft.

It also concerns The invention relates to a hydraulic motor according to the invention a vane cell machine according to one of the claims 1 to 7 is.

advantageously, can the hydraulic motor with oil operate. Then oil can be pumped into the hydraulic motor, which thus different units drives.

following Be different embodiments explained in more detail with reference to the accompanying drawings.

in the Show individual:

1 a cross section through a vane machine;

2 a perspective view of a shaft;

3 a perspective view of several internal combustion engines and pumps.

1 shows a vane machine 10 with a wave 11 , a grand piano 12 and an elliptical chamber 13 , During every turn of the shaft 11 practice the wing 12 also one turn, while at the same time moving back and forth relative to and perpendicular to the wave. The ends of the grand piano 12 thus take during each turn of the grand piano 12 a maximum and a minimum distance from the shaft 11 one. The maximum and minimum distance of the ends of the wing 12 from the wave 11 be taken when the wing 12 has reached the vertical position.

The wave 11 is near an inlet 14 and an outlet 15 between the inlet 14 and the outlet 15 on an inner wall of the chamber 13 at. Thus, an overflow of a medium from a pressure side of the chamber 13 to a suction side of the chamber 13 be prevented. As a result, high pressures can be generated in pump operation even at low speeds.

The wing 12 is maximally as long as the small diameter of the chamber 13 , However, it can also be slightly smaller than the small diameter of the chamber 13 to wear the chamber 13 and the grand piano 12 to prevent.

2 shows the wave 11 that have an area 20 with a larger diameter and areas 21 and 22 having a smaller diameter. The area 20 he is inside the chamber 13 arranged. The areas 21 and 22 are in accordance de storage openings in a housing 16 arranged. Thus, the shaft is without further fasteners against falling out of the housing 16 (please refer 1 ) secured.

The wave 11 has a slot 23 on, by the wing 12 moving back and forth simultaneously during its rotation. The slot 23 thus connects the wing 12 with the wave 11 , At the same time he leads the wing 12 in the float.

3 shows a pumping device 30 , with an internal combustion engine 31 , an internal combustion engine 32 , a gasoline pump 33 and a water pump 34 , The internal combustion engines 31 and 32 , the gasoline pump 33 and the water pump 34 are designed as vane machines, which form a common shaft 35 exhibit. Through the common wave 35 are the internal combustion engines 31 and 32 , the gasoline pump 33 and the water pump 34 arranged compactly. Furthermore, by the common arrangement of internal combustion engines 31 and 32 on the wave 35 produces a high and even performance.
