Abstract
A scroll-type compressor is disclosed having a discharge diffuser for improving the efficiency of the compressor, especially at off-design, high pressure ratio operating conditions. The diffuser allows fluid pressure recovery and consequently results in an efficient discharge process using a relatively small discharge port. It also reduces compression losses by reducing gas transport in the reverse flow direction.
