The balanced rotor rotates without metallic contact in a circular casing that contains liquid compressant usually water or oil .The rotor consisting series of blades and are shrouded at the
sides forming series of chambers.
The chambers of the rotor are filled with water or oil which rotates with the rotor following the contour of the casing .The sealing liquid recedes into the eccentric casing as the rotor
advances until the rotor chamber is empty.
The eccentric casing forces the sealing liquid back into the rotor chamber as the rotor advances further creating a piston like effect, this cycle occurs during each revolution of the rotor
.As the sealing liquid recedes from the champer it is replaced by gas drawn from the inlet port . As the rotates at 360 degrees the sealing liquid is forced back by the eccentric casing
into the rotor champer , the drawn gas is then compressed into the rotor champer and discharged through outlet port.
