Abstract
A scroll compressor comprising a rotation constraining device for restricting the rotation of the orbital scroll toward the principal axis rotational direction and for extending the constraining range of the orbital scroll toward the principal axis reverse rotational direction, and a compression chamber torque forming device for causing a pressure in a first compression chamber to be larger than that in a second compression chamber when the pressure in the compression chambers rises up abnormally high. The first compression chamber is formed between the wrap member inside surface of the fixed scroll and the wrap member outside surface of the orbital scroll and the second compression chamber is formed between the wrap member outside surface of the fixed scroll and the wrap member inside surface of the orbital scroll.
