Multiple-compressor system

A climate-control system comprising:

• a first compressor including a first shell and a first compression mechanism, the first shell including a first suction inlet through which working fluid is drawn into the first compressor for compression in the first compression mechanism;
• a second compressor including a second shell and a second compression mechanism, the second shell including a second suction inlet through which working fluid is drawn into the second compressor for compression in the second compression mechanism;
• a suction manifold having a first arm and a second arm, wherein the first arm is coupled to the first suction inlet and is configured to provide working fluid to the first suction inlet, wherein the second arm is coupled to the second suction inlet and is configured to provide working fluid to the second suction inlet;
• and
• a pressure-control flow path coupled to a discharge-pressure region of the climate-control system and to a suction-pressure region of the second compressor, wherein the pressure-control flow path includes a conduit and a valve that provide working fluid to the suction-pressure region of the second compressor at a pressure that is higher than pressure of working fluid in the first arm of the suction manifold.
