Abstract
A compressor may include a fluid-injection source, a shell, and first and second scroll members. The shell may define a suction pressure region. The first scroll member may include a first end plate and a first scroll wrap extending therefrom. The second scroll member may include a second end plate and a second scroll wrap extending therefrom. The first and second scroll wraps may cooperate to define a plurality of fluid pockets. The second end plate may include a first passage and a second passage. The second end plate may also include a first port and a second port extending through the second end plate and communicating with at least one of the fluid pockets. The first passage may be in communication with the suction pressure region. The second passage may be in communication with the fluid-injection source.
