During normal operation, the sliding vane 100 reciprocates in the sliding chute 310, the top end of the sliding vane 100 contacts with the roller 400 and moves at high speed under the action of the spring force Fk and the gas pressure difference force Fg between the back pressure of the tail and the gas pressure at the top, the sliding vane 100 generates a rotation moment M in the thickness direction under the action of the gas pressure difference force Fh in the chambers at both sides, the roller supporting force FN and the friction force Ft on the top, the sliding chute supporting force F and the friction force Ff on the side, and the motion inertia force Fix and Fiy on the whole, so that the sliding vane 100 tilts and generates abnormal collision friction with the inner wall of the sliding chute 310.

Based on this, to traditional compressor 10 when using, the slope of gleitbretter 100 along the thickness direction forces gleitbretter 100 side and spout 310 internal wall face collision contact, takes place frictional wear, and then influences the problem of compressor 10 performance and operation, provides a gleitbretter 100 and compressor 10, and this gleitbretter 100 and compressor 10 can slow down the slope of gleitbretter 100 when using, and then reduce compressor 10 loss.

Referring to fig. 1 and 2, in an embodiment, the compressor 10 includes an air cylinder 300 and a sliding vane 100, the air cylinder 300 is provided with a sliding slot 310, the sliding vane 100 is movably disposed in the sliding slot 310, referring to fig. 3 to 5, the sliding vane 100 includes a first surface 110 movably matched with the sliding slot 310, the first surface 110 faces a side wall of the sliding slot 310, the first surface 110 is provided with a first movable pressing portion 112 recessed inward, a bottom wall of the first movable pressing portion 112 is provided with a first pressure reducing portion 116 recessed inward, and the first movable pressing portion 112 is communicated with the first pressure reducing portion 116.

When the sliding vane 100 and the compressor 10 are used, the sliding vane 100 reciprocates in the sliding groove 310, a fluid medium flows into a region of the first movable pressing part 112 along a designed gap between the first surface 110 of the sliding vane 100 and the inner wall of the sliding groove 310 under the shearing action, and the inclination of the sliding vane 100 causes a difference in the size of the gap corresponding to different positions of the first movable pressing part 112, wherein the smaller the gap, the stronger the dynamic pressure effect, and the larger the fluid film bearing capacity, so that the sliding vane 100 can generate an action moment opposite to the inclination direction along the thickness direction, the inclination of the sliding vane 100 is slowed down, and the loss of the compressor 10 is reduced; further, set up first decompression portion 116 in first movable pressing portion 112 inside and can promote the volume of first movable pressing portion inner space, and then can have the throttle pressure reduction effect, make the membrane pressure evenly distributed of the liquid film that first movable pressing portion 112 dynamic pressure effect formed, avoid taking place the sudden change along the production effort of gleitbretter 100 thickness direction, and then can avoid gleitbretter 100 to strike spout 310 inner wall suddenly and produce the damage.

Referring to fig. 3, in another embodiment, the first surface 110 is provided with a second movable pressing portion 114 and a second pressure reducing portion 118 both recessed inward, the second movable pressing portion 114 and the second pressure reducing portion 118 are arranged at an interval, and a distance between the second movable pressing portion 114 and the second pressure reducing portion 118 is L, wherein L is greater than or equal to 5 μm and less than or equal to 2000 μm. At this moment, when second pressure reducing portion 114 and second pressure reducing portion 118 set up at an interval, because the membrane pressure when fluid flows out along second pressure reducing portion 114 is great, can reduce fluidic membrane pressure and then avoid taking place the sudden change along the production effort of gleitbretter 100 thickness direction through setting up second pressure reducing portion 118, and then can avoid gleitbretter 100 to strike the spout 310 inner wall suddenly and produce the damage.

Specifically, L may be: 5 μm, 100 μm, 500 μm, 1000 μm and 2000 μm.

Referring to fig. 3 and 4, specifically, the second dynamic pressure portion 114 is a second dynamic pressure groove, the second pressure reducing portion 118 is a second pressure reducing groove, and the extending directions of the second dynamic pressure groove and the second pressure reducing groove form an included angle with the flowing direction of the fluid on the first surface 110. Wherein the fluid flow direction on the whole first surface 110 should be consistent with the moving direction of the slider 100. Preferably, the extending direction of the second dynamic pressure groove and the second pressure reducing groove is arranged perpendicular to the flowing direction of the fluid on the first surface 110.

Furthermore, the depth of the first movable pressing part 112 is H1, wherein H1 is more than or equal to 1 μm and less than or equal to 50 μm. Thus, in this range, the dynamic pressure effect generated by the fluid in the first dynamic pressure portion 112 is more significant, and the inclination of the sliding vane 100 can be reduced, thereby reducing the loss of the compressor 10.

Further, the ratio of the sum of the areas of the first dynamic pressure holes to the area of the first surface 110 is a, wherein a is greater than or equal to 0.03 and less than or equal to 0.5.

Specifically, a may be: 0.03, 0.05, 0.1, 0.2, 0.25, 0.3, 0.4 and 0.5.

Specifically, the depth of the first pressure reducing hole is H2, wherein H2 is more than or equal to 0.02mm and less than or equal to 1 mm; therefore, in this range, when the fluid generates dynamic pressure effect in the first dynamic pressure portion 112, the film surface pressure of the fluid film is more uniform, so that the acting force generated along the thickness direction of the sliding piece 100 can be prevented from generating sudden change, and further the sliding piece 100 can be prevented from suddenly impacting the inner wall of the sliding slot 310 to generate damage.

Furthermore, the ratio of the depth of the first pressure reducing hole to the aperture of the first pressure reducing hole is b, wherein b is more than or equal to 0.1 and less than or equal to 10. Therefore, in the range, the fluid generates a significant dynamic pressure effect in the first dynamic pressure holes and the film surface pressure of the fluid film is more uniform, so that sudden change of the acting force generated in the thickness direction of the sliding sheet 100 can be avoided, and meanwhile, the fluid film generates enough bearing force to slow down the inclination of the sliding sheet 100.

Specifically, b may be: 0.1, 0.5, 0.8, 1, 3, 5, 7, 8 and 10.

Referring to fig. 8, in one embodiment, the first dynamic pressure portion 112 is a first dynamic pressure groove, the first pressure reducing portion 116 is a first dynamic pressure groove, and the first dynamic pressure groove has a similar function to the first dynamic pressure hole, and can both suppress the tilting of the slider 100; similarly, the first pressure relief groove and the first pressure relief hole both have similar functions and can prevent the sliding vane 100 and the inner wall of the sliding groove 310 from being abnormally collided and worn.

Referring to fig. 8, specifically, the first dynamic pressure groove has a strip-shaped groove, and the extending direction of the strip-shaped groove is consistent with the height direction of the cylinder 300, in other words, the extending direction of the strip-shaped groove is perpendicular to the sliding direction of the sliding chute 310.
