a variable volume control assembly, comprising a pressure regulator; wherein the pressure regulator is provided with a storage cavity, the storage cavity being configured to accommodate refrigerant, and the storage cavity is communicated with the variable volume control cavity; and
wherein the first sliding vane is so configured that when the first sliding vane slides along the first sliding vane groove the size of the another part extending into the variable volume control cavity is changed, such that the volume of the variable volume control cavity is changed accordingly; along with the change of the volume of the variable volume control cavity, refrigerant is capable of flowing between the variable volume control cavity and the storage cavity,
wherein the variable volume control assembly further comprises a control pipe, and the control pipe communicates the storage cavity with the variable volume control cavity, and
wherein the minimum sectional area of the control pipe is S, the maximum sliding speed of the first sliding vane is Cmax, the thickness of the first sliding vane is b, the height of the first compression cavity is H, and S>(1.57×10 −5 )bHCmax.

2. The compressor according to claim 1 , wherein the effective volume of the storage cavity is Va, the volume of the variable volume control cavity is Vb, and the maximum variable value of Vb that varies along with the sliding of the first sliding vane is Vbmax, and the relationship between Va and Vbmax satisfies: Va>5Vbmax.

3. The compressor according to claim 2 , wherein the relationship between Va and Vbmax satisfies: Va>10Vbmax.

4. The compressor according to claim 1 , wherein the relationship between S and bHCmax satisfies: S>(3.15×10 −5 )bHCmax.

5. The compressor according to claim 2 , wherein the variable volume control assembly further comprises a control pipe, and the control pipe communicates the storage cavity with the variable volume control cavity;
the variable volume control assembly further comprises an inlet flow channel, wherein the inlet flow channel comprises a pressure input port being configured to introduce refrigerant, and an outlet communicated with the storage cavity; and
the plane in which the outlet is located is a first boundary surface, the plane in which the end, communicated with the storage cavity, of the control pipe is arranged is a second boundary surface, and the volume between the first boundary surface and the second boundary surface in the storage cavity is the effective volume of the storage cavity.

6. The compressor according to claim 5 , wherein one end of the control pipe extends into the storage cavity through the bottom of the storage cavity, and extends to the inside of the storage cavity.

7. The compressor according to claim 1 , further comprising a second cylinder assembly, wherein the second cylinder assembly comprises a second cylinder body, a second roller, an upper flange and a baffle plate, the second cylinder body is provided with a second compression cavity, the second roller is arranged in the second compression cavity in a rotatable manner, the baffle plate is arranged between the first cylinder body and the second cylinder body, and the upper flange is arranged on a side, far away from the baffle plate, of the second cylinder body; and
wherein the first cylinder assembly further comprises a first roller which is arranged in the first compression cavity in a rotatable manner, the clearance between the first roller and the baffle plate is δa, the clearance between the second roller and the upper flange is δb, and δa>δb.

8. The compressor according to claim 7 , wherein δa>δb+4 μm.
