Guided-rotor compressor explained

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]

Uses

The guided-rotor compressor is under research as a hydrogen compressor for hydrogen stations and hydrogen pipeline transport.^[5]
