Definitions

  • the invention relates to a rotary piston machine in which a rotor rotates in a housing and radial in the rotor sliding slide between the housing and the rotor Form chambers with variable volume, one Even number of sliders is provided and each other diametrically opposed slider to a rigid unit are summarized.
  • Such a rotary piston machine is from GB 430 715 B. known.
  • the case has the shape of a Reuleaux triangle and the rotor is centered in this triangle arranged.
  • the advantage over such an arrangement the use of single-sided, spring-loaded sliders, that in the course of the rotation of the rotor, the housing walls only the inertial mass of the slide to its reciprocating Must overcome movement while centrifugal acceleration by combining diametrically opposed Slider is at least essentially canceled and spring forces, as always with single slides must be provided around the slide against the housing wall to press, omitted at all.
  • the invention aims to remedy this and a To specify rotary lobe machine of the type defined at the outset, in which each slide in one revolution of the rotor is only pushed back and forth once.
  • Refinements of the invention relate to the formation of the Slider and their guidance in the rotot or along the Housing.
  • Figures 1 to 3 show different configurations according to the invention usable housing shapes depending on the Ratio of parameters a and b.
  • the south pole S and the distances b and d are entered, where b is set at 1 is because the shape of the curve depends only on the ratio a / b and thus also depends on a / d according to the above relationship.
  • FIG. 1 to 3 How Figures 1 to 3 can be seen immediately are Housing shapes according to the invention in the range of a / b ⁇ 2 technically applicable, while at values of a / b, which are significantly higher, strong accelerations of the Sliders occur when they are in the equatorial position (parallel to the X-axis), being in addition in this Position still strongly pressing and from the slide level act directed contact forces from the housing wall and therefore such forms for technical use not allow.
  • Usable ratios a / b are between 1.0 and 2.5, preferably between 1.25 and 2.0, where a and b are the above have given meaning.
  • Fig. 4 shows a section normal to the axis of rotation Turbine according to the invention or one according to the invention Fan. Sliders 1 move in the rotor 19 in oil managed, as will be explained in detail below.
  • Fig. 5 shows a section normal to the axis of rotation Rotary piston internal combustion engine according to the invention.
  • Housing wall 32 is a suction opening 17 of a compressor stage schematically drawn, further an overcurrent channel 18, from the pressure side of the compressor stage to the suction side leads the engine stage and there an injection nozzle 20 entered in the expansion chamber.
  • the slide 1 of the compressor stage are in the oil again Rotor 19 out in the slides 21 of the rotor 22 in the combustion chamber this is for thermal reasons not possible.
  • FIG. 6 shows a section through the parallel rotor axes of the two rotors 19, 22 of FIG. 5.
  • this is Figure the rounded corner design of the housing chamber removable.
  • Fig. 7 shows a section normal to the rotor axes a rotary lobe internal combustion engine.
  • a pre-compressor outlet 26 opens into an expansion chamber 27, which ends in the discharge nozzle 28, can also be seen the schematically drawn suction opening 17 and the Overflow channel 18 from the pre-compressor stage in the Expansion stage leads.
  • the guided in the compressor rotor 19 Sliders 1 are preferably in turn guided in the oil this is thermally strong due to the combustion process loaded slide in the rotor 22 is not possible.
  • FIG. 8 shows a slider preferred according to the invention 1 in section, in side view and top view, grooves 3 can be seen, in which spring clip 4, of one of which is shown in FIG. 9 can be used.
  • oil channels 2 are provided, which according to the Centrifugal oil that flows into the rotor in which the Slider 1 is used in the region of its axis of rotation is fed, is transported to the outside and there the Slider 1 or the spring clip 4 while it is rotating lubricates and cools along the inside wall of the housing.
  • FIG. 9 shows a spring clip 4, which is in the grooves 3rd a slide 1 can be used and with Lubrication openings 5 is provided, from which the lubricating liquid can leak.
  • the arrows give the direction the (slight) elastic deformation due to centrifugal acceleration through which the seal on the Housing inner wall is improved.
  • the webs 34 between the two ends of the slide 1 lies around the individual sliders of a rotor at least the web width offset, so that the individual Slide in the rotor past each other radially movable are.
  • Such a rotor preferably consists of rotor segments 7, which are held together by rotor side walls 6.
  • elliptical rings 13 (Fig. 11) are used.
  • the Grooves 9 take segment seals 15 (Fig. 13), the Oil supply for the slide 1 and the spring clip 4 is carried out through an inlet opening 10 in the rotor shaft.
  • the 11 is an ellipse ring 13 in side view and Shown top view. The print direction is through Arrows indicated.
  • the ellipse ring 13 has an opening 16 for pressure and expansion compensation.
  • the ellipse ring 13 serves to seal the slide 1 opposite the rotor, are in the illustrated embodiment two such ellipse rings on each side of the rotor for each of the sliders 1, thus four ellipse rings per Slide, provided.
  • Fig. 12 From Fig. 12 is a rotor segment in front and side view can be seen from this, the grooves 8 for the Ellipse rings 13 and the grooves 9 for the segment seal 15 (Fig. 13) can be seen.
  • the holes 14 are used for assembly the side windows 6.
  • Fig. 13 is a segment seal 15 in front and side view shown. This segment seal 15 seals the rotor opposite the side housing wall and is trained to be self-pressing.
  • FIG. 14 shows a thermally heavy-duty rotor in Axial section, with a combustion chamber trough 26 in each segment is provided.
  • a single rotor segment is in 15 is shown in front and side view,
  • FIG. 16 shows an associated slide 21, which is different from the slide 1 due to the lack of oil supply and thus the lubrication different.
  • the webs 34 are as in the case of Slider 1 (Fig. 8) arranged.
  • the operation of the rotary lobe machine according to the invention is the same as the usual rotary lobe machines, besides the dynamic improvements of the slide movements and the special design of the slide this is not possible in terms of operation Change compared to the state of the art.
