Abstract
[Object] To provide a scroll compressor capable of improving compression efficiency. [Means of Solution] In a scroll compressor, a fixed scrollincludes a fixed base plate, and a fixed spiral wrapintegral with the fixed base plate, while a movable scrollincludes a movable base platefacing to the fixed base plateand a movable spiral wrapintegral with the movable base plateand meshing with the fixed spiral wrap. The movable scrollis formed with a supply passage, which is formed by an inflow openingopened to a distal end faceof the movable spiral wrapand communicatable with compression chamber, an outflow openingformed in the movable base plateto communicate with a back pressure chamber, and a communication holecommunicating the inflow openingwith the outflow opening, so as to communicate the compression chamberwith the back pressure chamberby an elastic deformation or displacement in a direction of the orbit axis R of the movable scroll
