Abstract
A fixed outer circumferential wall of a fixed scroll, a movable scroll, and a plate define a suction pressure space configured such that fluid flows from a suction chamber into the suction pressure space. The movable scroll and an opposed wall define a first back-pressure space. The plate and a back-pressure-chamber-defining recess of the opposed wall define a second back-pressure space. A back-pressure supplying groove of the opposed wall is configured to connect the first back-pressure space to the second back-pressure space, thereby supplying the fluid from the first back-pressure space to the second back-pressure space. A discharge hole of the plate is configured to connect the second back-pressure space to the suction pressure space, thereby discharging the fluid from the second back-pressure space to the suction pressure space. At least part of the discharge hole is overlapped with the back-pressure supplying groove in an axial direction.
