Type of positive-displacement rotary gas compressor
The guided-rotor compressor (GRC) is a positive-displacement rotary gas compressor. The compression volume is defined by the trochoidally rotating rotor mounted on an eccentric drive shaft[1][2] with a typical 80 to 85% adiabatic efficiency.[3]
History
The development of the GRC started in 1990 to minimize the use of compressor valve plates and springs by using simple inlet/discharge ports.[4]
