CO-ROTATING SCROLL COMPRESSOR

原文（中文）

If, in a virtual plane orthogonal to a drive axis (X), a midpoint (MP) between the center of a drive-side base circle () and the center of a driven-side base circle () is defined as a working point of compression loading generated in the radial direction of the drive axis (X), a direction orthogonal to a virtual line (VL) connecting two contact points, constituted of a first contact point (P) and a second contact point (P), at which a side surface of a driving spiral () and a side surface of a driven spiral () contact at an outermost circumferential side is defined as the loading direction (LD) of the compression loading, and the range over which the loading direction (LD) fluctuates during one revolution of a drive scroll () is defined as a fluctuation range (FR), a stator () defines a fixed axis (FX) inside a housing (), the drive axis is defined by a rotor () and is set so as to separate from the fixed axis (FX) in the loading direction (LD) included in the fluctuation range (FR) when not actuated, and so as to match or approach the fixed axis (FX) when actuated.
