Link 5 is installed on the pressure tube 3 by the interconnection technique of sealing, for example by bonding, welding, extruding or pressure injection-moulded sealing.
In a particularly preferred Placement, link 5 is fixed on the pressure tube 3 by infrared rays-laser welding technology.In this case, at least those and pressure tube 3 sections adjacent, link 5 form translucent, the IR wavelength that perhaps is positioned at 800 to 960nm scope at least can pass through, thus with suitable infrared rays-laser soldering device radiation by the outer cover of pressure tube 3 and in the contact area between the internal surface 5a of the outside of pressure tube 3 3b and link 5, obtain welding temperature.And pressure tube 3 is produced by black or dark plastics, thereby can absorb the energy that is given off by infrared rays-laser soldering device best.
Also has the connection of sealing with respect to connecting tube 6 with the link 5 that pressure tube 3 is tightly connected mutually.Sealing is connected among the shown embodiment and forms by the Sealing 7 that is arranged between link 5 and the connecting tube 6.
In the embodiments of figure 3, Sealing 7 is O shape rings, this O shape ring be maintained in the groove 13 on the outside 5b that is arranged at link 5 and its external diameter at least greater than the internal diameter of connecting tube 6, or the clear width of flow cross section 12.
This O shape ring or Sealing 7 have the cross section of lens shape in Fig. 3.As alternative, also can use O shape ring 7 (referring to the Figure 4 and 5) of circle, rectangle or rhombus to this.According to Fig. 4, O shape ring 7 is loaded in the groove 13 of link 5, it is foursquare shape basically that the cross section of this O shape ring 7 has, wherein the foursquare side of cross section make respectively recessed, therefore by O shape ring 7 not only with respect to the internal surface 6a of connecting tube 6 but also produced the Line of contact of two sealings respectively with respect to the outside 5a of link 5.This structure of Sealing 7 can guarantee the tightness between connecting tube 6 and the link 5 better.
But,, therefore also can use link 5 specifically created, that for example manufacture by elastomer in order to obtain link 5 with respect to being tightly connected of connecting tube 6.
Understandablely be, as for example being press-fitted incompatible realization by adhesive being coated on link outside 5b and/or the connecting tube internal surface 6b or by between link outside 5b and connecting tube internal surface 6b, forming in the optional or additional encapsulation scheme between link 5 and the connecting tube 6.In this case, especially possible is to realize that by link 5 and connecting tube 6 are hooked mutually shape is sealed.
Fig. 6 shows an alternative embodiment of the invention, wherein connecting tube 6 and link 5 crimping (Vercrimpt).In this case, the outside 5b of link 5 has preparation and geometrical shapies connecting tube 6 crimping, groove 14 shapes complementary, that be spill.After realizing inserting or be pressed in the connecting tube 6 together with pressure tube 3 to link 5, connecting tube 6 passes through the appropriate device crimping at least on its circumferential position, therefore the outer cover section 6d of connecting tube 6 is close on the groove 14 of spill, and has produced the axial restraint that is maintained at the link 5 in the connecting tube 6 in this wise.
As shown in Figure 6, the outer cover section 6d of the crimping of the groove 14 of the spill of link 5 or connecting tube 6 is disposed on the position that surrounds the end regions that is maintained at the pressure tube 3 in the link 5.By above-mentioned crimping process, the outer cover section 6d zone below, link 5 that is positioned at connecting tube 6 is crushed on the pressure tube 3 more consumingly, and the seal action between link 5 and pressure tube 3 is further enhanced.Such structure especially is proved to be favourable in the link 5 of elastomer mode of execution, because can save independent Sealing 7 is set.
In another enforcement distortion of Fig. 9, link 5 manufactures one with pressure tube 3.Such structure can be favourable aspect manufacturing technology.
For stablizing reason, what go out as shown in Figure 1 is such, and on the height of end segments 3c in being maintained at connecting tube 6 or link 5, pressure tube 3, connecting tube 6 is fixed on the wall of compressor housing 1.
In addition, under the situation of the mode of execution of the crimping of pressure piping 3,6, the Sealing 7 of geometrical shape can be adopted and any amount of Sealing 7 (also can referring to Fig. 7 and 8) can be adopted with any cross section, perhaps such as already mentioned, also can cancel, because the enough good sealing effect of connecting tube 6 obtains by the link 5 with seal geometry relatively.
