りる使用に適した回転圧縮機が得られる。General (The performance required for vane type rotary compressors differs depending on the application, but superchargers for automobile engines are required to withstand high pressure and a wide range of rotation speeds. In order to achieve this, a rotating sleeve is provided within the center housing, an air bearing chamber is formed between the outer circumferential surface of the rotating sleeve and the inner circumferential surface of the center housing to floatingly support the rotating sleeve, and the rotating sleeve is A rotary compressor in which a rotary sleeve is rotated together with a rotor by incorporating a vane and a 10-tube was previously proposed by the present applicant (Japanese Patent Laid-Open No. 58-65988, Patent Application No. 58 -286
No. 08). By adopting such a configuration, heat generation due to one rotation of the vane is suppressed, and rotation without lubrication is reduced by 1!7, making it suitable for use with high pressure, large flow rate, and a wide range of rotation speeds. A compressor is obtained.

とが望まれる。On the contrary, in the above-mentioned rotary compressor, in order for the rotary sleeve, which is floatingly supported within the center housing, to continue smooth tf rotation, it is necessary not only to have contact between the rotary sleeve and the center housing, but also to have contact between both ends of the rotary sleeve and the side housing. It is necessary to prevent contact with To achieve this, it is necessary to prevent the rotating sleeve from shifting in the axial direction as much as possible, and to ensure that an appropriate amount of clearance is always maintained between both ends of the rotating sleeve and the 4-noid housing to act as an air cushion or air bearing during rotation. Must be. In particular, the rotation sleeve (this is the relationship between the inlet and outlet of the gas to be sucked and compressed, the inlet and outlet of the gas supplied to the air bearing chamber, and the inlet and outlet of the gas to be supplied to and discharged from the air bearing chamber). The axial position of the rotating sleeve may become unstable if the thrust force is applied to the side. It is desirable not to touch the sliding parts, and it is desirable not to cause abrasion, scuffing, or even burning due to contact.

It consists of 1 C pieces installed at equal intervals.

In this case, the gas at both ends of the rotary sleeve is communicated through the through hole of the rotary sleeve, so the IF forces at both ends are balanced, and the displacement of the rotary sleeve in the axis 1 direction -/'j direction is suppressed. . In addition, air cushions are formed at both ends of the blind hole J to secure the volume of the gas chamber in a semi-circular state at both ends of the rotary sleeve 1, and when the rotary sleeve shifts in one direction, The force in the blind hole on the opposite side increases and the rotating sleeve is pushed back, and the pressure in the blind hole on the opposite side decreases and the rotating sleeve is pulled back. Therefore, the rotating sleeve is automatically moved to the center position even if a thrust force of 1~ is applied, and the rotation sleeve is automatically moved to the center position when the left and right balanced floating support state is maintained ([15]). The lance is always secured during rotation, preventing contact with the side housing and ensuring smooth rotation.

The clearance between 4 is air 11'lll and 18
In order to maintain the internal pressure (for your information), a small gap is set.
! Create a gas chamber for one person. Therefore, at rotation 4Q, the sleeve 17 is bent in the rotational direction by the thrust force, and five holes are formed in the center 11.1 in that direction, in the clearance between the hole 3G and the end of the rotating sleeve. The volume of the gas chamber is reduced, the pressure increases accordingly, and the reaction force tries to push back the rotating sleeve 17. In other words, a gas chamber of an appropriate volume formed in the middle hole 36 can prevent the rotation sleeve 17 from dislocating.
Provides an air cushion effect. - At the opposite end of the force, the volume of the gas chamber formed by the blind hole 3G expands and the pressure decreases, so conversely, the rotating sleeve 1
I try to pull 7 back. Therefore, rotating sleeve 1
7, when the moi device is displaced, pressure is applied from both ends to return it to its original position, and if a thrust force is applied, the rotating sleeve 17 is automatically returned to the center position. The clearance at both ends is always maintained at an appropriate amount of 4r to prevent contact with the sliding part vJ34, and a good floating support state of the rotating sleeve is stabilized and maintained.

This has the advantage of being able to prevent the rotating sleeve from shifting in the axial direction, and to ensure lances that are required at both ends at all times during rotation.
