Definitions
- the invention relates to a rotary piston machine in which a rotor rotates in a housing and radially displaceable slides form variable-volume chambers between the housing and the rotor, an even number of slides being provided and diametrically opposed slides being combined to form a rigid unit are.
- Such a rotary piston machine is known from GB 430 715 B.
- the housing has the shape of a Reuleaux triangle and the rotor is arranged centrally in this triangle.
- the advantage of such an arrangement compared to the use of one-sided, spring-loaded slide is that in the course of the rotation of the rotor, the housing walls only have to overcome the inertial mass of the slide for its reciprocating movement, while the centrifugal acceleration due to the combination of diametrically opposite slides is at least essentially canceled out and spring forces, as must always be provided in the case of individual slides in order to press the sliders against the housing wall, are eliminated at all.
- a rotary lobe machine of the type mentioned at the outset is therefore subjected to significantly reduced wear compared to other rotary lobe machines with individually movable slides.
- DD-33 914 A in which the housing has a circular cross section and the rotor arranged eccentrically in the housing also essentially has a circular shape, but with recesses, the in cross section are delimited by a circular arc section from which the rotor is cut out in order to increase the size of the chambers which form.
- the (four) slides are pressed by springs from the rotor outwards against the casing wall, which together with the centrifugal acceleration leads to high contact pressures and high wear.
- the invention aims to remedy this situation and to provide a rotary piston machine of the type defined in the introduction, in which each slide is only reciprocated once in the course of one revolution of the rotor.
- r ( ⁇ ) ⁇ from 2 / [a 2 cos 2 (l ( ⁇ + ⁇ / 2)) + b 2 sin 2 (1 ( ⁇ + ⁇ / 2))] ⁇ l / 2
- Embodiments of the invention relate to the formation of the slide and their guidance in the rotot or along the housing.
- FIG. 4 shows a section through a turbine or fan
- FIG. 5 shows a section through a 2-stage rotary piston internal combustion engine
- FIG. 6 shows an axial section through a rotary piston internal combustion engine
- FIG. 7 8 shows a section through a rotary piston internal combustion engine
- FIG. 8 shows a slide in section, top view and side view
- FIG. 9 shows a spring clip in front view, in top view and in side view
- FIGS. 1 to 3 show different designs of housing shapes that can be used according to the invention depending on the ratio of parameters a and b.
- the coordinate systems used, the south pole S and the distances b and d are entered, where b is fixed at 1, since the shape of the curve depends only on the ratio a / b and thus also according to the above relationship a / d.
- Useful ratios a / b are between 1.0 and 2.5, preferably between 1.25 and 2.0, where a and b have the meaning given above.
- Fig. 4 shows a section normal to the axis of rotation of a turbine according to the invention or an inventive
- FIG. 5 shows a section normal to the axis of rotation of a rotary piston internal combustion engine.
- An intake opening 17 of a compressor stage is shown schematically in the housing wall 32, furthermore an overflow duct 18 which leads from the pressure side of the compressor stage to the intake side of the engine stage and there an injection nozzle 20 is introduced in the area of the expansion chamber.
- the slides 1 of the compressor stage are again guided in the oil in the rotor 19; for slides 21 of the rotor 22 in the combustion chamber, this is not possible for thermal reasons.
- FIG. 6 shows a section through the parallel rotor axes of the two rotors 19, 22 of FIG. 5.
- the rounded corner design of the housing chamber can be seen from this figure.
- the bearings 29 for the rotors 19, 22 and the toothed wheels 31 which drive the compressor rotor 19 are entered.
- Fig. 7 shows a section normal to the rotor axes of a rotary piston internal combustion engine.
- a pre-compressor outlet opening 26 opens into an expansion chamber 27, which ends in the discharge nozzle 28.
- the schematically drawn intake opening 17 and the overflow channel 18, which leads from the pre-compressor stage into the expansion stage, can also be seen.
- the guided in the compressor rotor 19 Sliders 1 are preferably again guided in the oil, while this is not possible in the case of the sliders in the rotor 22 which are thermally highly loaded by the combustion process.
- FIG. 8 shows a slide 1 which is preferred according to the invention in section, in side view and in plan view, grooves 3 being visible, in which spring clips 4, one of which is shown in FIG. 9, can be used.
- oil channels 2 are provided, which, due to the centrifugal acceleration, transport oil to the outside in the region of its axis of rotation, which is supplied to the rotor in which the slide 1 is used, and there the slide 1 or the spring clip 4 during its rotation lubricates and cools along the inside wall of the housing.
- FIG. 9 shows a spring clip 4 which can be inserted into the grooves 3 of a slide 1 and which is provided with lubrication openings 5 from which the lubricating fluid can escape.
- the arrows indicate the direction of the (slight) elastic deformation due to the centrifugal acceleration, which improves the seal on the inner wall of the housing.
- the webs 34 between the two ends of the slide 1 are offset in the individual sliders of a rotor by at least the web width, so that the individual sliders are arranged in the rotor so as to be radially movable past one another.
- Fig. 10 shows a rotor for oil-lubricated slide 1, which is therefore not thermally high load, otherwise the oil will become blocked.
- Liquids other than 01 can also be used for lubrication, whereby both 01 and the other liquids can be used for cooling.
- the slide can be cooled by liquids such as water and Lubrication is important, especially since the oil contamination can no longer be removed from the vacuum.
- Such a rotor preferably consists of rotor segments 7, which are held together by rotor side walls 6. Ellipse rings 13 (FIG. 11) are inserted into grooves 8. The grooves 9 receive segment seals 15 (FIG. 13), the oil supply for the slide 1 or the spring clip 4 takes place through an inlet opening 10 in the rotor shaft.
- the 11 shows an ellipse ring 13 in a side view and a top view.
- the direction of pressure is indicated by arrows.
- the ellipse ring 13 has an opening 16 for pressure and expansion compensation.
- the ellipse ring 13 serves to seal the slide 1 from the rotor.
- two such ellipse rings are provided on each side of the rotor for each of the slide 1, thus four ellipse rings per slide.
- FIG. 12 A rotor segment in front and side view can be seen from FIG. 12, from which the grooves 8 for the elliptical rings 13 and the grooves 9 for the segment seal 15 (FIG. 13) can also be seen.
- the holes 14 are used to mount the side windows 6.
- a segment seal 15 is shown in front and side view. This segment seal 15 seals the rotor from the side housing wall and is designed to be self-pressing.
- FIG. 14 shows a thermally highly resilient rotor in axial section, a combustion chamber trough 26 being provided in each segment.
- a single rotor segment is shown in front and side view in FIG. 15, FIG. 16 shows an associated slide 21, which differs from the slide 1 due to the lack of oil supply and thus of the lubrication differs.
- the webs 34 are arranged as in the slide 1 (FIG. 8).
- the method of operation of the rotary lobe machine according to the invention is the same as that of the conventional rotary lobe machines, except for the dynamic improvements in the slide movements and the special design of the slide, which is possible as a result, since the operation has not changed compared to the prior art.
