Abstract

The invention provides a double-rotor variable-volume compressor, comprising a first air cylinder group and a second air cylinder group. The first air cylinder group comprises a first air cylinder, a first sliding sheet and a locking mechanism, wherein the first air cylinder is provided with a first sliding groove; the first sliding sheet is arranged in the first sliding groove and is provided with a positioning hole or a positioning groove; the locking mechanism is provided with a locking piece; the locking piece is provided with a locking position and an unlocking position, wherein the locking position extends into the first sliding groove and is matched with the positioning hole or the positioning groove so as to lock the first sliding sheet, and the unlocking position is used for unlocking the first sliding sheet. The double-rotor variable-volume compressor provided by the utility model can convert between single-cylinder operation and double-cylinder operation, and has higher operation stability and reliability. Meanwhile, a sliding sheet of a second air cylinder is not stressed by a pull force towards the outer side of the air cylinder in the double-cylinder operation, so that the sliding sheet is tightly adhered to a roller; the leakage loss and the like can be reduced; and the properties of the compressor can be improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a double-rotor variable capacity compressor. Background technique [0002] A dual-rotor variable capacity compressor is disclosed in the prior art, which has the following technical features. By setting a permanent magnet, an electromagnet, and a tension spring on the back of the slide of a cylinder, a holding mechanism such as a tension spring is provided for the slide to provide a direction to the cylinder. The pulling force on the outside makes the sliding vanes and rollers separate under the action of the pulling force when the cylinder is under high pressure, so as to stop the compression of a cylinder and change the displacement of the compressor to achieve variable capacity. In the disclosed technical solution, the first cylinder is equipped with a spring, and the spring hole of the second cylinder is not equipped with a spring. The position of the slide is controlled ...
