Abstract: A compressor includes a housing, a first scroll member supported within the housing and having a first end plate with a discharge passage, and a second scroll member supported within the housing and having a second end plate with a second spiral wrap extending therefrom and meshingly engaged with the first spiral wrap to form a series of pockets. A first aperture extends through the first end plate and is in communication with a first product of the series of pockets. A modulation assembly axially biases the first scroll member into engagement with the second scroll member when the first aperture is in communication with a suction pressure region of the compressor.
