Guided-rotor 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
As the guided-rotor compressor rotates around the eccentric shaft, the central rotor pumps fluid
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]
Uses
The guided-rotor compressor is under research as a hydrogen compressor for hydrogen stations and hydrogen pipeline transport.[5]
