13a and oil guide groove 18d is supplied to the sliding part between bottom wall part 13p and rotary shaft 16.
There are following situations：Rotor 18 is axially pressed by the differential pressure of the front side of rotor 18 and rear side, rotor 18
The gap between gap or rotor 18 and bottom wall part 13p between back side panel 15 becomes smaller, confession of the lubricating oil to rotary shaft 16
Narrow to flow path.Especially, there are following situations：When blade-tape compressor 10 is restarted from halted state, mainly due to row
Go out the discharge pressure in region 35 and rotor 18 is pressed by side forwards, the gap between rotor 18 and bottom wall part 13p becomes smaller.In this reality
In the blade-tape compressor 10 for applying mode, even if in this case, it, also can be to rotation due to being provided with oil guide groove 18d
Axis 16 fully supplies lubricating oil.
Especially, the sliding position between bottom wall part 13p and rotary shaft 16 in from accumulate lubricating oil discharging area 35 from
The position opened, so being to be difficult to be supplied to the place of lubricating oil, however by the way that oil guide groove 18d is arranged, so as to ensure bottom wall
The lubricity of sliding part between portion 13p and rotary shaft 16.
The top of blade 19 is pressed to the pushing force of inner peripheral surface of cylinder chamber 14d it is excessively weak in the case of, send out sometimes
Raw refrigerant gas is revealed from the gap of cylinder chamber 14d and blade 19 to adjacent discharge chambe 21 or flutter.On the contrary in blade
In the case that 19 pushing force is excessively strong, it some times happens that the consumption power of blade-tape compressor 10 increases or cylinder portion 14
The abrasion of inner peripheral surface 14c or blade 19.Therefore, the pushing force of blade 19 needs to be maintained at appropriate intensity.
In the state that pressure in discharge chambe 21 is low, the initial stage of such as suction stroke or compression travel, blade 19 by
To push back that power is low, so the pushing force of blade 19 is got higher, the consumption power of blade-tape compressor 10 becomes larger.
The sliding being imported into the lubricating oil in logical oil groove 13a using oil guide groove 18d between bottom wall part 13p and rotary shaft 16
Portion, thus enable that it is being connect with logical oil groove 13a, in the back pressure of suction stroke or the back pressure chamber of compression travel 41 reduce.By
This, can inhibit the consumption power of blade-tape compressor 10 to become larger.
As lubricity other means for ensuring the sliding part between bottom wall part 13p and rotary shaft 16, it is also considered that the bottom of by
The end face 13s of wall portion 13p is set as concave curved planar, or the width of logical oil groove 13a is made to become larger.In these cases, bottom wall part 13p
End face 13s recess part and back pressure chamber 41 it is opposite always to, lubricating oil be easy from back pressure chamber 41 be leaked to rotor 18 with
