Carry out external this serial procedures being discharged to above-mentioned scroll compressor at the refrigerant outlet in above-mentioned third shell 13
It is repeated.
In the process, above-mentioned rotary shaft 3 can be in a rotatable way by above-mentioned first bearing 71 and above-mentioned second
Bearing 72 is supported, and above-mentioned convolution scroll plate 42 is come by above-mentioned 3rd bearing 73 to be carried out relative to above-mentioned rotary shaft 3
The mode of rotation supports, in order to reduce the assembly (hereinafter referred to as circumnutation body) of the 3rd bearing 73 and scroll plate 42 of circling round
Weight and size, above-mentioned 3rd bearing 73 is formed as being different from the bearing of above-mentioned first bearing 71 and above-mentioned second bearing 72
73。
Specifically, in order to make friction loss minimize, it is fixed on the above-mentioned first bearing 71 and above-mentioned second of above-mentioned shell 1
Bearing 72 can be respectively formed as ball bearing.
Conversely, with circumnutation is carried out together with above-mentioned convolution scroll plate 42, with the weight of above-mentioned circumnutation body and
It is also lower than the weight of ball bearing and smaller and cost that there is size the above-mentioned 3rd bearing 73 of proportionate relationship to be formed as
Honest and clean needle bearing (needle roller bearing) or slide bushing (slide bush) bearing.
This above-mentioned 3rd bearing 73 can make scroll compressor by reducing weight and the size of above-mentioned circumnutation body
Weight, size, spin balancing, durability, noise, vibration, cost and the packaging of machine entirety are improved.
Also, above-mentioned 3rd bearing 73 can be connected in such a way that scheduled pressing-in force is pressed into above-mentioned shaft sleeve part 423.
That is, being different from the present embodiment, when 3rd bearing 73 is formed as ball bearing, in order not to between the inner ring and ball for carrying out point contact
And apply excessive power between outer ring and ball, 3rd bearing 73 is not pressed into shaft sleeve part 423, or even if 3rd bearing 73 to
Shaft sleeve part 423 is pressed into, also should be to be faintly pressed into (with the pressing-in force less than above-mentioned scheduled pressing-in force), as a result,
3rd bearing 73 can be led to the problem of to be detached from from shaft sleeve part 423.But in case of the present embodiment, due to above-mentioned third axis
It holds 73 and is formed as the durability needle bearing more more outstanding than ball bearing or slide bushing bearing, thus the 3rd bearing 73 can
It is connected with above-mentioned shaft sleeve part 423 in a manner of the pressing-in force indentation of bigger by than being formed as ball bearing the case where.Can more have as a result,
Prevent to effect the disengaging of above-mentioned 3rd bearing 73.
On the other hand, due to being connected in a manner of indentation between above-mentioned 3rd bearing 73 and above-mentioned convolution scroll plate 42,
It can be thus deformed in above-mentioned convolution scroll plate 42, and generate refrigerant leakage and compression performance to reduce.That is, when above-mentioned the
When three bearings 73 are pressed into along the axis direction of above-mentioned rotary shaft 3 to above-mentioned shaft sleeve part 423, in above-mentioned shaft sleeve part 423, above-mentioned
It circles round runner plate portion 421 and above-mentioned convolution roll bending 422 generates axis direction deformation, and the front end of above-mentioned convolution roll bending 422 is from upper
The compressing surface 411a for stating fixed mirror plate portion 411 separates as clearance G more broader than scheduled clearance G, passes through the clearance G to broaden and produces
Raw refrigerant leakage, to which compression performance reduces.Also, as above-mentioned 3rd bearing 73 is formed as needle bearing or slide bushing
Bearing substitutes ball bearing, and is connected with above-mentioned shaft sleeve part 423 in such a way that the pressing-in force of bigger is pressed into, this convolution vortex
The problems caused by deformation of disk 42, is even more serious.
In consideration of it, in the case where being connected with above-mentioned 3rd bearing 73, according to the above-mentioned convolution of the present embodiment
Scroll plate 42 may include the deformation preventing portion 424 of the deformation for preventing the convolution scroll plate 42.
Specifically, in a ring, above-mentioned convolution runner plate portion 421 may include above-mentioned shaft sleeve part 423：Convolution runner plate portion first position
4211, on the basis of above-mentioned shaft sleeve part 423, it is located at radial outside；And convolution runner plate portion second position 4212, with above-mentioned axle sleeve
On the basis of portion 423, it is located at radially inner side, above-mentioned deformation preventing portion 424 may include making above-mentioned shaft sleeve part 423 and above-mentioned convolution runner plate
The notch (notchportion) 4241 of the reduced stiffness of connecting portion between portion's first position 4211.

The position of the deformation for runner plate portion second position 4212 of circling round, can be from second back side of above-mentioned convolution runner plate portion second position 4212
4212b (face at the back side of the compressing surface 4212a in 4212 side formation convolution runner plate portion of second position in convolution runner plate portion) prominent shape
At.That is, the thickness between the compressing surface 4212a in above-mentioned convolution runner plate portion and above-mentioned second back side 4212b is resistance in compression refrigerant
Counter-force, and be formed to make the scheduled thickness that the weight of above-mentioned convolution scroll plate 42 and size minimize (hereinafter, base
Quasi- thickness Ts), the thickness between the compressing surface 4212a in above-mentioned convolution runner plate portion and the front end face 4242a of above-mentioned circular top part 4242
(hereinafter, thickness Td of circular top part) can be more than said reference thickness Ts.
This above-mentioned circular top part 4242 is by making the rigidity of above-mentioned convolution runner plate portion second position 4212 increase, to prevent this
The deformation for runner plate portion second position 4212 of circling round, as shown in fig. 6, the front end of above-mentioned convolution roll bending 422 can be prevented from above-mentioned solid
The compressing surface 411a of horizontal glass plate portion becomes the situation more wider than scheduled clearance G.
This prevents let out as the clearance G of convolution roll bending 422 and fixed mirror plate portion 411 increases caused refrigerant
Leakage and compression performance reduce.
Also, despite the presence of the indentation of above-mentioned 3rd bearing 73, but above-mentioned convolution roll bending 422 and fixed mirror plate portion 411
Clearance G keeps scheduled level, without subsequently being handed over above-mentioned convolution roll bending 422, therefore can be by manufacturing cost
Rise and the deformation of convolution roll bending 422 is preventive from possible trouble.
Herein, above-mentioned circular top part 4242 makes the above-mentioned convolution scroll plate 42 caused by the formation of the circular top part 4242
The increase of weight minimizes, and in order between above-mentioned rotary shaft 3 and above-mentioned 3rd bearing 73 lubrication and cooling, can be from above-mentioned the
The central part of two back side 4212b protrudes to be formed.That is, above-mentioned circular top part 4242 can only be formed in above-mentioned second back side 4212b's
Central part.Instead, the front end face 311 with above-mentioned rotary shaft 3 is formed between above-mentioned circular top part 4242 and above-mentioned shaft sleeve part 423
The oil groove 4243 separated can be formed between above-mentioned oil groove 4243 and the front end face of above-mentioned rotary shaft 3 311 for storing for moistening
Slide onto the oil storage space 4244 for stating the lubricating oil between rotary shaft 3 and above-mentioned 3rd bearing 73.At this point, above-mentioned oil groove 4243 is formed
For the inner peripheral surface 423b of the peripheral surface 4242b of above-mentioned circular top part 4242, above-mentioned second back side 4212b and above-mentioned shaft sleeve part 423, phase
