Abstract
A compressor, including: a first rotor being rotatable around a first axis, the first rotor including a first portion and a second portion; and a first shaft carrying the first portion and the second portion, the first shaft having a first end and a second end that are oppositely arranged. The first rotor is configured to be applied with a preset acting force in a direction from the first end toward the second end or from the second end toward the first end during rotation. The size of the compressor can be reduced with the displacement of the compressor remaining substantially unchanged.

A compressor, comprising:
- a first rotor being rotatable around a first axis, the first rotor comprising a first portion and a second portion;
- a first shaft configured to carry the first portion and the second portion, the first shaft having a first end and a second end that are oppositely arranged;
- and
- a housing accommodating the first rotor and a portion of the first shaft;
- wherein the first rotor is configured to be applied with a preset acting force in a direction from the first end toward the second end or from the second end toward the first end during rotation,
- a second rotor being rotatable around a second axis, the second rotor comprising a third portion engaged with the first portion and a fourth portion engaged with the second portion;
- a second shaft configured to carry the third portion and the fourth portion;
- and
- the housing accommodating the second rotor and a portion of the second shaft;
- wherein the second rotor is configured to be applied with a preset acting force in a direction from the first end toward the second end or from the second end toward the first end during the rotation of the first rotor and the second rotor;
- and
- wherein at least one of the first portion and the third portion is provided with first air supply holes, the second portion and the fourth portion is provided with second air supply holes, the first air supply holes and the second air supply holes are configured to be different from each other to generate an air pressure difference during the rotation of the first rotor and the second rotor to form the preset acting force.
