In contrast, in present embodiment 1, the amount for being stranded in the refrigerating machine oil of the upper surface of bearing 9 is reduced, thus, it is possible to
The enough inside for inhibiting the refrigerant comprising refrigerating machine oil to be expelled to container 2.Therefore refrigerating machine oil can be inhibited to hold by being set to
The discharge pipe 3 of device 2 and the outside for flowing out to container 2, lead to the reduced performance of refrigeration machine.In addition in refrigerating machine oil exhaustion, i.e.,
Make the damage for preventing axis 7 and bearing 9 and regard bearing 9 as rolling bearing, can also reduce slippage loss.
Conventionally, there is known the outer peripheral edge portion in discharge silencer is formed with gap or the outlet of discharge refrigerating machine oil
Compressor 1, but due to without the refrigerating machine oil for being accumulated in the upper surface of bearing is guided the construction to gap or outlet,
Therefore insufficient for discharge refrigerating machine oil.In contrast, present embodiment 1 due to bearing 9 have rake 24, thus
The refrigerating machine oil for the upper surface for being attached to bearing 9 can be guided to oil extraction hole 32.Therefore the effect of discharge refrigerating machine oil is higher.
In addition, base portion 9a also has flat part 23, the flat part 23 is adjacent with rake 24, and outer edge is eliminated the noise with discharge
Device 11 contacts, and outlet 21 is formed in flat part 23.That is, the oil extraction hole 32 formed in the position for being equivalent to the front end of rake 24
It is detached with outlet 21.The effect for inhibiting noise is not interfered if even if therefore forming oil extraction hole 32.
In turn, oil extraction hole 32 is formed in the first line segment 81 for making benchmark line segment 80 rotate 30 ° in silencer 11 is discharged
Between so that benchmark line segment 80 is rotated -30 ° of second line segment 82, the benchmark line segment 80 is centered on the central point of outlet 21
And extend from the central point of outlet 21 to the central point of axis 7.That is, oil extraction hole 32 is more detached with outlet 21.Even if therefore
Oil extraction hole 32 is formed, the effect for inhibiting noise will not be more interfered.
