Fig. 2 is the structural representation of the determine vortex disk disk body of the automobile air conditioner compressor of the present invention；
Fig. 3 is the upward view of the determine vortex disk of the automobile air conditioner compressor of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
The present invention rather than limitation the scope of the present invention, after the present invention has been read, those skilled in the art are each to the present invention's
The modification of the kind equivalent form of value falls within the application appended claims limited range.
As shown in Figure 1, Figure 2 and Figure 3, the determine vortex disk of a kind of automobile air conditioner compressor, including determine vortex disk body 1, set
The upper surface of determine vortex disk body 1 boss 2 and be located at the scroll wrap 3 of the lower surface of determine vortex disk body 1；Determine vortex disk body 1
End face 11 including circle and the side wall 12 positioned at the bottom of end face 11；The side wall of the scroll wrap 3 is provided with several oil storage holes.
Boss 2 includes being located at the seal groove 21 on the periphery of boss 2 and is located at tabletting 23 and the banking stop 24 of the centre of boss 2；It is close
Sealing groove 21 forms ring to join end to end, and three through holes 22 and a return-air hole 25 are provided with boss 2；Three tops of through hole 22 are provided with
The tabletting 23 of rigid banking stop 24 and elasticity；Tabletting 23 is to include the E font structures of three forks, and three forks are covered each by three
