Face scroll spring is placed in connecting portion 142 and is in compressive state.
Specifically, plane scroll spring includes the first connection end and the second connection end, and the first connection end is located at plane scroll
The middle part of spring, the second connection end is located at the circumferential edge of plane scroll spring.First connection end is connected to the hole of connecting hole 142
Wall, the second connection end is connected with the inwall of connecting portion 142.It is appreciated that tensioning mechanism 130 be alternatively spiral tensioning device etc. can
To play tensioning function to flexible piece 140, flexible piece 140 is made to keep the mechanism of enough tension force.
It is appreciated that in other embodiments, connecting portion 142 can omit, and that is, the two ends in motion portion 141 are all and tensioning mechanism
130 connections, now flexible piece 140 expands into list structure.
Illustrate the work process of rotary compressor below in conjunction with an embodiment：
As shown in Fig. 2 flexible piece 140 is around being located on eccentric part 122 and tensioning mechanism 130, flexible piece 140 is in tensioning mechanism
Enough tension force is kept in the presence of 130.
As shown in figure 4, electric machine assembly band dynamic crankshaft 120 rotates in the counterclockwise direction, and it is set around the motion of eccentric part 122
Portion 141 tensioning mechanism 130 relatively extends so that motion portion 141 is fitted with the cavity wall of cylinder chamber 111.Motion portion 141 is with bent axle 120
Rotation swing along the cavity wall of cylinder chamber 111, and start, from air entry 112 air-breathing, to start simultaneously at the gas compression to compression chamber.
As shown in figure 5, electric machine assembly band dynamic crankshaft 120 rotates 180 degree in the counterclockwise direction, motion portion 141 is with bent axle 120
Rotation along cylinder chamber 111 cavity wall continue swing.Motion portion 141 tensioning mechanism 130 relatively starts to shrink at so that motion portion 141
Fit with the cavity wall of cylinder chamber 111, and continue, from air entry 112 air-breathing, to continue the gas compression to compression chamber simultaneously.
As shown in fig. 6, electric machine assembly band dynamic crankshaft 120 is rotated further in the counterclockwise direction, motion portion 141 fastener relatively
Structure 130 continues to shrink, and motion portion 141 continues to swing with the cavity wall rotating along cylinder chamber 111 of bent axle 120, and continues from air-breathing
Mouthful 112 air-breathings, simultaneously compression chamber start aerofluxuss.
Electric machine assembly band dynamic crankshaft 120 rotates 360 degree in the counterclockwise direction, and aerofluxuss terminate, and return to original state, such as Fig. 2
Shown.So bent axle 120 rotates the cavity wall swing one week driving flexible piece 140 along cylinder chamber 111 one week, thus by gas from suction
Air cavity is compressed to compression chamber, finally discharges cylinder, then completes air-breathing-compression-exhaust process.
Each technical characteristic of embodiment described above can arbitrarily be combined, for making description succinct, not to above-mentioned reality
The all possible combination of each technical characteristic applied in example is all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all it is considered to be the scope of this specification record.
Embodiment described above only have expressed several embodiments of the present utility model, and its description is more concrete and detailed,
But therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, some deformation can also be made and improve, these broadly fall into
Protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
