Fig. 5 further illustrates the details of the structure of external sealed parts 4 and outer spring 5 in the flat-top seal ring that is installed in the scroll compressor.As stated, the effect of outer spring 5 in the design of flat-top seal ring mainly contains two: externally sealed member 4 provides axial compression load all the time, helps external sealed parts 4 to be in the axial seal state all the time; And bound feet (upward axis is to extensional surface) 52 displacement of external sealed member 4 diametrically that outer spring 4 is axially holded up limits.

Particularly, acoustical panel 30 as shown in Figure 5 and the distance H of deciding between the scroll element 66 are not definite values.Use movably external sealed parts 4 to seal and decide scroll element 66 and acoustical panel 30, to press the gas of chamber B and low pressure chamber A in isolating.External sealed parts 4 shapes are by flat form bending compression moulding.As shown in Figure 5, external sealed parts 4 can have and comprise the portion of extending axially 41 and the L shaped cross section of extension part 42 radially.Eliminate acoustical panel 30 and decide the influence that distance H changes between the scroll element 66 through moving axially of external sealed parts 4.

External sealed parts 4 can fall during shutdown, and the pressure reduction during start between mesolow chamber B and the A can not 100% touch acoustical panel 30 with external sealed parts 4 jack-up.The precompression of the radially extensional surface 51 external sealed members 4 of outer spring 5 can 100% touch acoustical panel 30 with external sealed parts 4 jack-up, thereby needs to guarantee that outer spring 5 be in pressurized state all the time.

Notice that radially the thickness of extension part 42 can be greater than the interval that between the radially extensional surface 51 of outer spring 5 and acoustical panel 30, forms, to guarantee that outer spring 5 is in pressurized state all the time.But in long-time high-temperature aging, external sealed parts 4 have creep to recover back the trend of flat form, and promptly external sealed parts 4 internal diameters can paste acoustical panel 30 to the internal diameter direction slippage, and pressure chamber B and low pressure chamber A leakage in can causing makes seal failure.Can be about aforementioned circumstances referring to Fig. 6.Fig. 6 is that diagram is installed in the sectional view that the flat-top seal ring appearance in the scroll compressor was lost efficacy.As shown in Figure 6, when external sealed parts 4 to the internal diameter direction slippage to a certain degree the time, can between low pressure chamber A and middle pressure chamber B, form leak D, thereby cause seal failure.

Turn back to Fig. 5, for fear of the generation of seal failure, outer spring 5 is provided with upward axis to extensional surface 52.The upward axis that touches outer spring 5 when the internal diameter of external sealed parts 4 is during to extensional surface 52, and outer spring 5 can external sealed member 4 produces and stops, thereby prevents external sealed parts 4 to continue to move, and guarantees effectively sealing.

In addition,, further on outer spring 5, be provided with and extend axially surface 53 downwards for the possible radial displacement of the portion that extends axially 41 that stops external sealed parts 4, as shown in Figure 5.

For the effectively radial displacement of control external sealed parts 4, can the upward axis of outer spring 5 is higher to extensional surface 52 designs.Promptly under nature, after outer spring 5 was assemblied on the scroll component, upward axis belonged to height to the height of extensional surface 52 a little more than acoustical panel 30 sealing surfaces.Like this, the upward axis that is in assembling condition will receive the downward pressure of 30 pairs of outer springs of an acoustical panel 5 and fit with acoustical panel 30 sealing surfaces to extensional surface 52, thereby guarantee that external sealed parts 4 will be stopped to intrinsic displacement fully.

Fig. 7 is the stereogram of the structure of the outer spring 5 in a kind of flat-top seal ring of diagram, and Fig. 8 is the stereogram of the detailed structure of diagram outer spring 5 as shown in Figure 7.

Because external sealed parts 4 can be annular, correspondingly outer spring 5 can have ring part 56, and is as shown in Figure 7.Beam 55 tilts to extend upward from ring part 56.Beam 55 has radially extensional surface 51 at its upwardly extending end that tilts.Between per two adjacent beams 55, link together through the radially extensional surface 51 of crossbeam 54 with them.In other words, can think that radially extensional surface 51 is on the crossbeam 54.Further, extend axially the end that surface 53 is arranged on extensional surface 51 radially and crossbeam 54 downwards.In addition, on ring part 56, also be provided with positioning part 57, be used to guarantee outer spring 5 and scroll component centering.

It should be noted that in this outer spring 5, upward axis is arranged on the crossbeam 54 to extensional surface 52, particularly can be referring to Fig. 8.

Because the radially extensional surface that plays sealing function 51 of outer spring 5 is on same beam that is the crossbeam 54 to extensional surface 52 with the upward axis that plays limit function; So when upward axis when extensional surface 52 receives a downward power; Radially extensional surface 51 also can be depressed simultaneously, external sealed parts 4 should be received from the precompression of extensional surface 51 radially reduce even disappear.This possibly be disadvantageous to keeping the applying of external sealed parts 4 upper surfaces and acoustical panel 30 sealing surfaces in some cases.

The utility model also provides other a kind of outer spring 7, shown in Fig. 9 and 10.Fig. 9 is the stereogram of diagram according to the structure of the outer spring 7 in the flat-top seal ring of present embodiment, and Figure 10 is the stereogram of the detailed structure of diagram outer spring 7 as shown in Figure 9.

As shown in Figure 9, in outer spring 7, be provided with two kinds of beams: the beam 71 and the beam 72 that is used for limit function that are used for sealing function according to present embodiment.Beam 71 outside sealed members 4 provide axial compression load, make external sealed parts 4 and acoustical panel 30 form the axial seal state.Beam 72 forms with beam 71 dividually, and can receive when being installed in compressor in the time acoustical panel 30 axial pressure and with the acoustical panel applying, to limit moving radially of external sealed parts 4.

Different with outer spring 5 shown in Figure 7, be not provided with adjacent two crossbeams that beam links together according to the outer spring 7 of present embodiment.This outer spring design makes two major functions of outer spring obtain decoupling zero: beam 71 external sealed members 4 provide axial loading, and beam 72 is responsible for the radial displacement of restriction external sealed parts 4.

Outer spring 7 can have ring part 76, and beam 71 tilts to extend upward from ring part 76 with beam 72.Beam 71 can have the surface 73 of radially extending at its end.Further, beam 71 can have downward axially extended surperficial 74 at the end on surface 73.The precompression of surface 73 external sealed members 4 can 100% touch acoustical panel 30 with external sealed parts 4 jack-up, thereby needs assurance outer spring 7 be in pressurized state all the time.Surface 74 can stop the possible radial displacement of the portion that extends axially 41 of external sealed parts 4.It is emphasized that; When having, external sealed parts 4 comprise the portion of extending axially 41 and radially during the L shaped cross section of extension part 42 (for example can referring to Fig. 5); Radially the thickness of extension part 42 can be greater than the interval that forms between the surface 73 of radially extending of the beam in outer spring 7 71 and the acoustical panel 30, to guarantee that outer spring 7 is in pressurized state all the time.

In addition, on ring part 76, also positioning part 77 be can be provided with, outer spring 7 and scroll component centering are used to guarantee.

And then beam 72 can have the width of variation.Through the width of adjustment beam 72, rigidity and intensity that can Regulation spring be to guarantee the working life of spring.Further, beam 72 can extend axially to have at its end and make progress axially extended surperficial 75.To touch making progress of beam 72 axially extended surperficial 75 the time when the internal diameter of external sealed parts 4, and beam 72 can external sealed member 4 produces and stops, thereby prevents external sealed parts 4 to continue to move, and guarantees effectively sealing.And then, for the effectively radial displacement of control external sealed parts 4, can axially extended surperficial 75 designs of making progress of beam 72 are higher.Promptly under nature, after outer spring 7 was assemblied on the scroll component, axially extended surperficial 75 the height that makes progress of beam 72 was a little more than acoustical panel 30 sealing surfaces place height.Like this, be in making progress of assembling condition axially extended surperficial 75 and will receive the downward pressure of 30 pairs of beams of an acoustical panel 72 and fit, thereby guarantee that external sealed parts 4 will be stopped to intrinsic displacement fully with acoustical panel 30 sealing surfaces.

According to present embodiment, after outer spring 7 is installed in the compressor, when surface 75 receives axial pressure and moves downward, the supporting effect of influence surface 73 external sealed members 4 no longer.

Preferably, beam 71 can replace layout with beam 72 on ring part 76.More preferably, beam 71 can be evenly distributed on ring part 76 with beam 72.Design can guarantee the stressed even of external sealed parts 4 like this.

In sum, the external sealed member of outer spring play good axial loading and radially the qualification effect be the key that the external sealed parts keep the reliability of sealing.When outer spring axially loads when the radial displacement limitation function is on same beam, if a reinforcement side function wherein, then the opposing party's function possibly weakened.When above-mentioned functions is placed in two kinds of Liang Shangshi respectively, Each performs its own functions for each beam, less interfering with each other.
