In some embodiments of the utility model, between the side wall of first step 216 and the bottom land of vane slot 213 away from
The side wall for being more than or equal to 3mm and/or second step 217 from D1 is more than or waited with the distance between the bottom land of vane slot 213 D2
In 3mm.
Specifically, shown in reference picture 3- Fig. 4, in certain embodiments, the size of vane slot 213 meets：First step
The distance between 216 side wall and the bottom land of vane slot 213 D1 are more than or equal to 3mm, and the side wall and cunning of second step 217
The distance between the bottom land of film trap 213 D2 is more than or equal to 3mm.
In some optional embodiments, the size of vane slot 213 meets：The side wall of first step 216 and vane slot 213
The distance between bottom land D1 be more than or equal to 3mm, and between the bottom land of the side wall of second step 217 and vane slot 213 away from
Do not limited from D2.
Or in other optional embodiments, the size of vane slot 213 meets：The side wall and cunning of second step 217
The distance between the bottom land of film trap 213 D2 is more than or equal to 3mm, and the bottom land of the side wall of first step 216 and vane slot 213 it
Between distance D1 do not limit.
So, for the less rotary compressor of offset 100, the size of vane slot 213 is shorter, then D1 or D2 are with regard to energy
It is bigger, so as to make position while welding of the vane slot 213 at first step 216 or second step 217, be thus advantageous to
Ensure weldquality, and then ensure cylinder 21 and housing 10 is welded and fixed effect.
In some embodiments of the utility model, the minimum between the bottom wall 2161 of air entry 214 and first step 216
The minimum range D4 that distance D3 is more than or equal between 3mm and/or air entry 214 and the bottom wall 2171 of second step 217 is more than
Or equal to 3mm.
Specifically with reference to shown in Fig. 2, Fig. 4, in certain embodiments, the bottom wall 2161 of air entry 214 and first step 216
Between minimum range D3 be more than or equal to 3mm, and the minimum between air entry 214 and the bottom wall 2171 of second step 217
Distance D4 is more than or equal to 3mm.
In some optional embodiments, the minimum range D3 between the bottom wall 2161 of air entry 214 and first step 216
More than or equal to 3mm, and the minimum range D4 between air entry 214 and the bottom wall 2171 of second step 217 is not limited.
Or in other optional embodiments, the minimum between the bottom wall 2171 of air entry 214 and second step 217
Distance D4 is more than or equal to 3mm, and the minimum range D3 between air entry 214 and the bottom wall 2161 of first step 216 is not limited
It is fixed.
Thus, it is possible to first step 216, second step 217 is avoided to it also avoid welding at a distance of relatively closely welding operation is influenceed
First step 216 when connecing, the weld seam at second step 217 influence each other.
Shown in reference picture 4, in certain embodiments, the minimum wall thickness (MINI W.) D5 of cylinder 21 diametrically is more than or equal to 20mm.
As Figure 1-Figure 2, rotary compressor 100 also includes the reservoir 30 outside housing 10, reservoir 30
Blast pipe 40 is plugged in air entry 214, it is possible thereby to which flash gas in reservoir 30 easily is passed into suction muffler
In 27.Specifically, blast pipe 40 is welded to connect with cylinder 21, and centre does not have Taper Pipe transition, is thus advantageous to save Taper Pipe, and then
It is cost-effective.
In a specific embodiment, cylinder 21 is formed by the cutting of mild steel steel pipe, because mild steel possesses high intensity, and
Machinability is good, therefore, advantageously reducing processing cost.
Further, cylinder 21 is welded to connect with housing 10, because mild steel is also equipped with preferable welding performance, therefore by
When cylinder 21 made of mild steel welds with housing 10, welding effect is preferable, and the fixation of cylinder 21 and housing 10 is relatively reliable, by
This obtained rotary compressor 100 can bear the hyperbaric environment inside suction muffler 27, be advantageous to extend rotary compressor
100 service life.
