Abstract
A scroll compressor includes a casing, a compressor mechanism, a housing, a partition member and a flow mechanism. The compressor mechanism is accommodated in the casing. The compressor mechanism includes a fixed scroll and a movable scroll arranged to form a compression chamber. The housing is disposed on a back side of the movable scroll to form a back pressure space between the housing and the movable scroll. The partition member is disposed in an interior of the casing to form an auxiliary space communicating with the back pressure space. The a flow mechanism is arranged to enable a fluid to flow between the back pressure space and the auxiliary space, and the compression chamber in a process of compression.
