Abstract
A motor-driven compressor includes a back pressure region that pushes a movable scroll against a fixed scroll. The back pressure region is located at a side of the movable scroll located proximate to an opposing member. A defining portion, which is arranged on a movable end face, contact an opposing end face to define the back pressure region and a suction pressure region. The opposing member includes a communicating portion. An orbiting motion of the movable scroll moves the defining portion. This intermittently communicates the communicating portion with the back pressure region and the suction pressure region.
