Definitions
- the invention relates to an impeller for a side channel turbomachine designed in particular as a side channel blower, which has impeller vanes with limited impeller blades in at least one of its end faces, the impeller vanes having a plan view of the end face of the impeller
- Impeller each having a radially inner inlet region and a radially outer outlet region and the impeller blades in the inlet region and the outlet region are each inclined differently.
- the invention is based on the problem of designing an impeller of the type mentioned above so that it allows a high efficiency of the side-channel flow machine and is particularly easy to manufacture.
- the impeller blades are divided into different sections.
- Each of these sections has an easily manageable shape.
- Such forms can be inexpensively made of plastic by injection molding by means of easy to demoulding tools.
- these sections can be manufactured for the respective function in the inlet region and in the outlet region for the highest possible efficiency.
- the impeller according to the invention enables the generation of a particularly high efficiency of the side channel flow machine at a low production cost.
- the staggered portions of the impeller vanes and their inclined transition region could extend to the bottom of the vane chambers.
- a flow along the bottom of the vane chamber is free of turbulence when the end of the impeller blades remote from the end face has a continuous circular arc.
- the impeller blades have different angles to the orthogonal of the end face of the impeller in the inlet area and in the outlet area.
- the turbomachine equipped with the impeller contributes, according to another advantageous development of the invention, when the inlet area is more inclined in the direction of rotation of the impeller than the outlet area.
- the impeller can be particularly easily demolded according to another advantageous embodiment of the invention, if the Impeller blades in the inlet area and in the outlet area are each designed flat or almost flat.
- the edge of the running ⁇ paddle blades adjacent to the front side has the same wall thickness over the entire length.
- the impeller blades could, for example, be inclined in the circumferential direction of the impeller as in the prior art. To further simplify the manufacture of the impeller, however, it contributes according to another advantageous embodiment of the invention, if adjacent to the front edge of the impeller ⁇ blades in the inlet region and in the outlet region points to the center of the impeller.
- the invention allows numerous embodiments. To further clarify its basic principle, one of them is shown in the drawing and will be described below. This shows in Fig.l schematically a side channel flow machine for
- Fig.2a greatly enlarged a vane chamber of the impeller
- FIG. 2. "
- FIG. 1 shows schematically a driven by an electric motor 1 side channel flow machine 2 for the extraction of gases from a fuel tank 3.
- the turbomachine 2 has a front of a housing wall 4 rotatably mounted, and mounted on a shaft 5 of the electric motor 1 impeller 6.
- Die Gezzaus ⁇ Wall 4 has an inlet channel 7 and an outlet channel 8. To simplify the drawing, the inlet channel 7 and the outlet channel 8 are shown rotated in the plane of the drawing.
- a part-annular channel 9 is arranged in the housing wall 4.
- the part-annular channel 9 extends from the inlet channel 7 to the outlet channel 8.
- the impeller 6 has a ring of blade chambers 10 opposite the partially annular channel 9. The blade chambers 10 are explained in more detail with reference to FIG.
- the intake passage 7 is connected to an activated carbon filter 11 disposed on the fuel tank 3.
- an activated carbon filter 11 disposed on the fuel tank 3.
- gases can be sucked from the side channel Strö ⁇ tion machine 2.
- the side channel Strömungs- machine 2 and the activated carbon filter 11 may also be arranged such that the gases are blown out of the activated carbon filter 11.
- the activated carbon filter 11 is part of a venting device 12 of the fuel tank 3.
- Figure 2 shows an enlarged portion of the rim blade chambers 10 having portion 4 of the impeller 4 of Figure 1.
- the blade chambers 10 are bounded by impeller blades 13.
- FIG. 2a shows one of the blade chambers 10 with two impeller blades 13.
- the impeller blades 13 each have an edge 14 terminating with the end face of the impeller 4 with a radially inner inlet region 15 and a radially outer outlet region 16.
- the inlet region 15 and the outlet region 16 are arranged offset to one another and connected to each other via an inclined transition region 17.
- the adjacent edge 14 on the front side in the form of a tangent hyperbolic function.
- the side facing away from the front End of the edge 14 has a continuous circular arc 18.
- the impeller blades 13 in the inlet region 15 and in the outlet region 16 are differently inclined to the direction of rotation of the impeller 4.
- FIG. 2 shows that the edge 14 of the impeller blades 13 adjoining the front side with the inlet regions 15 and the outlet regions 16 into the center of the impeller 4 ways.

Abstract
L'invention concerne un rotor (4) pour une turbomachine régénératrice (2). Ce rotor présente des aubes, pour lesquelles la zone d'entrée (15) est décalée de la zone de sortie (16). La zone d'entrée (15) est reliée à la zone de sortie (16) par une zone de transition (17) inclinée. Le rotor assure un rendement excellent à la turbomachine régénératrice (2) et peut être fabriqué d'une manière particulièrement peu onéreuse.
