US 11,525,446 B2 · Compressor and air conditioner

Abstract

A compressor and an air conditioner are provided. The compressor includes a main shaft, a first cylinder and a second cylinder. The main shaft sequentially passes through the first cylinder and the second cylinder and can rotate therein, to compress refrigerant entering the first cylinder and the second cylinder. The second cylinder has an inner cavity capable of receiving the main shaft. A volume variation control cavity in communication with the inner cavity is provided in a side wall of the inner cavity, and a sliding vane is provided inside the volume variation control cavity. The volume variation control cavity can be selectively connected to a gas inlet and a gas outlet of the compressor, to change gas pressure in the volume variation control cavity, and drive the sliding vane to abut against or be separated from the main shaft by the gas pressure in the volume variation control cavity.

Dependent claims

A compressor, comprising:

a main shaft, a first cylinder and a second cylinder;
wherein the main shaft is configured to sequentially pass through the first cylinder and the second cylinder, and configured to be rotatable in the first cylinder and the second cylinder, so as to compress refrigerant entering the first cylinder and the second cylinder;
and the second cylinder has an inner cavity capable of receiving the main shaft;
a volume variation control cavity in communication with the inner cavity is provided in a side wall of the inner cavity;
a sliding vane is provided in the volume variation control cavity;
and the volume variation control cavity is configured to be selectively connected to a gas outlet of the compressor, so as to change gas pressure in the volume variation control cavity, and drive the sliding vane to abut against or be separated from the main shaft by the gas pressure in the volume variation control cavity;
a cover plate;

5 more elements

The compressor according to claim, the compressor comprises a regulating component;

the volume variation channel is in communication with the volume variation control cavity;
the high-pressure channel is in communication with the gas outlet;
and the low-pressure channel is in communication with the gas inlet;
and the regulating component is configured to switch between a first position where the volume variation channel is connected to the high-pressure channel, and a second position where the volume variation channel is connected to the low-pressure channel, so as to control pressure of gas passing through the volume variation channel and entering the volume variation control cavity.
