用いられる一般的のベーン型圧縮機について説明する。In a vane type compressor, sufficient oil must be supplied without running out of oil in order to lubricate the sliding surfaces between the vanes and the pump housing, as well as lubricate the seals, the rotating shaft, and its bearings. This oil supply mechanism will be explained with reference to a general vane type compressor used in a cooling device shown in FIGS. 1 and 2.

に送出される。It is formed in the case 1 by a cam ring 2a, a front side block 2b, and a rear side block 2C,
A pump housing 2 having a cam wire surface 2d on the inner surface is provided, and a thrift 3m of one digit is installed in the pump housing 2.
is formed in the radial direction, and a cylindrical rotor 3 in which a plate-shaped vane 3b is fitted so as to move forward and backward is disposed. It is oil-tight and press-fitted into the inner end of the rotating shaft 6 that passes through the front head 1a. The f14 oil is mixed in the refrigerant, and when the rotating shaft 6 is driven, the rotor 3
rotates, and the centrifugal force generated by this rotation and the slit)
The vane 3b is pushed out in the radial direction by the oil pressure of 114 oil acting on the bottom of the vane 3a, and rotates while slidingly contacting the cam surface 2d. Each time each vane 3b passes through the inflow lower formed in the cam ring 21, the refrigerant is sucked into the pump working chamber 9 through the suction port 8 provided in the front head 1m. The volume of the pump working chamber 9, which is formed by the adjacent pipes 73b and the cam circumferential surface 2d, changes from the minimum to the maximum in the suction stroke and from the maximum to the minimum in one compression stroke, and the volume of the suctioned and compressed The refrigerant pressurized during the stroke is discharged from the outlet lO by pushing open the discharge valve 11, and this cycle is repeated to perform compression. The compressed refrigerant is passed through the lubricating oil separator 12
The lubricating oil mixed therein is separated and once discharged into a discharge pressure chamber 13 formed between the pump housing 2 and the case 1, and then sent to the cooling circuit through the discharge port 14.

上記の循環が繰返される。During the above operation, the lubricating oil separated by the lubricating oil separator 12 and collected at the bottom of the case 1 is formed in the front side block 2b by the suction effect due to the pressure in the discharge pressure chamber 13 and the rotation of the rotating shaft 6. The lubricating oil reaches the oil #14JI of the bearing part 4 from the lubricating oil supply hole 15 and lubricates the bearing part 4. This lubricating oil passes through the clearance of the bearing part 4 and flows into the back pressure chamber 3CK of the rotor 3 on one side, and the back of the vane 3bK. While applying pressure, the sliding surface of the vane 3b is sealed and one part flows into the shaft sealing chamber 5 and is sealed with the fi411N of this part. Thereafter, the lubricating oil is introduced into the pump working chamber 9, and when it is discharged together with the refrigerant into the discharge pressure chamber 9, it is separated from the refrigerant through the FI4 lubricating oil separator 12 and accumulates at the bottom of the case 1.
The above cycle is repeated.

１５内の潤滑油は自重により落下し、冷媒と入替わる。By the way, when the air conditioner is operating, the refrigerant compressor is constantly turned on and off to prevent the evaporator from freezing. Furthermore, the compressor of a vehicle cooling system, which is rotated by a driving engine, is constantly subject to changes in rotational speed. Under normal operating conditions, if the compressor is stopped for several tens of seconds, the pressure difference between the suction side and the discharge side disappears in the compressor due to leakage from the sliding parts, and the inside of the 11iIII oil supply hole 15 is reduced. The lubricating oil falls under its own weight and is replaced by the refrigerant.

The pressure and flow rate of the refrigerant flow discharged into the refrigerant chamber 13 change significantly, leaking into the lower part of the discharge pressure chamber 13, and the lubricating oil is agitated to the extent that it temporarily becomes atomized. Therefore, in this case as well, as the oil level of the lubricating oil supply hole 15 drops, the refrigerant flows through the lubricating oil supply hole 15 due to the discharge pressure at this time. When a large amount of refrigerant enters the permanent back pressure chamber 3C from the lubricating oil supply hole in this way, since the refrigerant is a compressible fluid, the back pressure of the page 73b changes, causing a decrease in compression performance, and the sliding Failure to do so may result in failure of seals or internal problems. In addition, the bearing part 4 of a vane type compressor is generally a brane, which has a simple structure and excellent vibration resistance.
Although a radial bearing is used, this brane radial bearing is susceptible to oil starvation and foreign matter getting caught, and when refrigerant is sucked into the bearing portion 4, seizure due to oil starvation is likely to occur.

に繰返し低下する。The operation of the oil supply device i20 configured as described above will be explained next. First, when there is sufficient lubricating oil in the discharge pressure chamber 13, the float 24 floats to the position 24' shown by the broken line, and the opening 21m of the oil reservoir 21 is opened, and the lubricating oil flows through the opening 23m of the guide tube 23. It enters the oil sump 21 through the conduit 22

The pressure of this and the suction action generated by the rotation of the rotating shaft 60 clean the bearing part, apply back pressure to the vane 3b, and lubricate and seal the sliding surface of the vane 3b.
lubricate and seal. When the compressor changes from OFF to ON, or when the rotation speed of the compressor suddenly fluctuates as the engine speed changes, the lubricating oil in the discharge pressure chamber 13 is strongly absorbed by the refrigerant. Due to the disturbance, the oil level temporarily and repeatedly lowers from the position of the opening 23m of the guide tube 23 of the oil supply device 20.

することができる。As described above, the present invention includes a cam ring, a front side block and a rear side block joined to both sides of the cam ring, and a pump housing formed by K.
A rotor arranged in the pump housing, in which a plurality of slits are formed in the radial direction, each Slin) K vane is inserted into the pump housing so as to be able to move forward and backward, and a back pressure chamber that communicates with the slits is formed inside, and a front side. The front side block includes a rotating shaft supported by a bearing part of the block and having the rotor attached to the inner end thereof, and a lubricating oil supply hole in the front side block that supplies lubricating oil to the bearing part of the rotating shaft and the back pressure chamber of the rotor. A vane compressor is provided with a discharge pressure chamber between the pump housing and the case, and has an appropriate capacity;
An opening is formed in the upper surface, and a lower part is connected to the lubricating oil supply hole of the front side block to form an oil reservoir, and an opening is formed in the opening of the oil reservoir and opens to the discharge pressure chamber. An oil supply device is installed in the discharge pressure chamber, and includes a guide cylinder and a float that floats and sinks while being guided inside the guide cylinder to open and close the opening of the oil reservoir. Even if the rotation speed of the compressor suddenly fluctuates due to a change in the engine rotation speed, and the A lubricant in the discharge pressure chamber is violently disturbed, and the lubricant level drops to the level of the FI4 lubricant oil supply hole, the capacity is maintained appropriately. The oil sump of the oil supply system holds lubricating oil, and the float closes the opening of the oil sump, and the lubricating oil in the oil sump is agitated by the refrigerant, and the refrigerant flows through the conduit and M oil hole to the bearing part and the back of the rotor. Prevent entry into the pressure chamber. Furthermore, even if the compressor is stopped for a long time, the lubricating oil supply hole is sealed with S lubricating oil in the oil reservoir and becomes round, replacing the refrigerant and preventing it from falling. Therefore, refrigerant may enter the bearing and cause oil to run out, resulting in seizure of the bearing. Also, refrigerant may enter the back pressure chamber, resulting in reduced compression performance, poor sealing of vane sliding parts, and failures due to poor lubrication. This can be prevented.
