A compressor includes a shell, a compression mechanism, and an axial biasing system. The shell defines a first passage forming a first discharge passage. The compression mechanism includes first and second scroll members meshingly engaged with one another and forming a series of compression pockets. The first scroll member includes a second discharge passage. The axial biasing system includes a biasing member having first and second surfaces generally opposite one another. The first surface includes a first radial surface area exposed to an intermediate pressure from one of the compression pockets and a second radial surface area exposed to a discharge pressure. The second surface includes a third radial surface area exposed to the intermediate pressure. The biasing member is axially displaceable between first and second positions. The biasing member axially engages the first scroll member when in the first position.
