Theguided-rotor compressor (GRC) is a positive-displacement rotarygas compressor. The compression volume is defined by thetrochoidally rotating rotor mounted on an eccentric drive shaft[1][2] with a typical 80 to 85%adiabatic efficiency.[3]
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]
The guided-rotor compressor is under research as ahydrogen compressor forhydrogen stations andhydrogen pipeline transport.[5]
