Definitions
- the invention relates to a vacuum pump with a cylindrical working chamber in which between a suction port and an outflow opening a slider is arranged, which slides in a guide slot of an eccentric rotary piston.
- the main disadvantages of these embodiments are each in the insufficient gap seal the storage of the slider, as well as in the high friction losses between the piston drum and the cylindrical working chamber.
- Rotary piston pump has become known in the case of a slide also between the inlet opening and the outlet opening oscillating in
- Rotary piston in which in the inner wall of the working chamber between the suction port and the outflow opening a bearing groove is arranged, in which a pendulum provided with a slider pendulum is mounted such that it is arranged during the orbital motion of the rotary piston with its pendulum shaft in a radially in the rotary piston , from
- the object of the invention is therefore to develop a working by means of an eccentric orbital vacuum pump, which eliminates the aforementioned disadvantages of the prior art, it is simple and robust, with minimal material use manufacturing technology is easy to manufacture and assemble, thereby the manufacturing and Maintenance costs significantly lowers, the pumped medium is not contaminated by lubricant, at the same time significantly increases the tightness between the eccentric rotary piston and the slide, so that even in a single-stage compression a high vacuum can be achieved, also the wear of the modules should be minimized so that even at very high speeds high reliability and long life can be guaranteed.
- FIG. 1 the vacuum pump according to the invention (in section in A-A according to Figure 3) shown in side view;
- FIG 2 the detail "Z" of the vacuum pump according to the invention according to Figure 1;
- FIG 3 the vacuum pump according to the invention in section at B-B, according to Figure 1.
- FIG. 1 the vacuum pump according to the invention is shown in section in a side view (section A-A according to FIG. 3).
- a suction port 3 and an outflow opening 4 are arranged.
- a drive shaft At a centric in the working chamber arranged drive shaft is non-rotatably mounted a disc with an eccentrically arranged bearing pin 5.
- bearing pin 5 On this bearing pin 5 is rotatably rotatable as a rotary piston in its working width, the bearing journal length, for example, manufactured as Kunststoffoffspritzgußteil, orbiter 6 is arranged.
- This Orbiter consists of two nested circular rings, an outer, flexible, slotted circular ring, the sealing ring 7, and a centrally disposed in this, inner, the bearing pin 5 receiving annulus, the bearing ring 8. Both are together according to the invention, as explained below, resilient connected.
- These guide webs 11 serve to receive a guide pendulum sheet 13
- This arranged between the guide webs 11 guide pendulum blade 13 is provided with a pendulum head 12, and surmounted in the region of the excess width
- FIG. 2 shows again in detail the detail "Z" of the vacuum pump according to the invention according to FIG.
- FIG. 3 now shows the vacuum pump according to the invention according to FIG. 1 in FIG.
- the drive shaft 1 is mounted by means of plain bearings 16 in a pump housing 17.
- the working chamber 2 is optimized in a preferred, manufacturing technology
- Design is formed by a cylindrical pot-shaped stator 18, with the
- the guide pendulum blade 13 is guided by the arranged also in this area on the bearing ring 8 guide webs 11.
- Deformation of the entire orbiter 6 causes. This defined deformation of the orbiter 6 according to the invention causes the sealing ring 7 to bear against the inner wall of the stator 18 in a sealing manner with radial prestressing during the entire eccentric revolution.
- the eccentrically arranged bearing pin 5 presses the flexible, guided by the guide pendulum blade 13 exactly, elastic lateral surface of the orbiter 6 without a gap sealingly against the inner wall of the stator 18.
- the vacuum pump according to the invention is simple and robust.
- the vacuum pump according to the invention as shown in Figure 3, be "removed" as a tandem pump.
- 21 may, as shown in Figure 3, be an oil pump.
- tandem pump for example for use in
- Aperture bore with the oil volume of the gallery of the internal combustion engine in Connection so that at the same time an optimal common lubricant supply of the sliding bearings 16 of both pumps, the vacuum pump and the oil pump, is ensured with filtered oil.
