Claim Text:
1. A system comprising: a first inlet configured to receive fluid that is to be compressed; a first piston configured to rotate around a first eccentric of a shaft in an orbital fashion in order to compress the fluid, the first piston being coated with an abradable coating, the fluid being used as a lubricant for lubricating the first piston, the use of the fluid for lubricating and the abradable coating eliminating a need of another lubricant for lubricating the first piston; a first outlet configured to discharge the compressed fluid; a second inlet configured to receive, from a separator device, one or more exhaust gases that have been separated from the fluid, the one or more exhaust gases being a subset of gases forming the fluid; a second piston configured to rotate around a second eccentric of the shaft in the orbital fashion, axial surfaces of the second piston being parallel to axial surfaces of the first piston, the second piston being coated with the abradable coating, the one or more exhaust gases being used as a lubricant for lubricating the second piston, the use of the one or more exhaust gases for lubricating and the abradable coating of the second piston eliminating a need of another lubricant for lubricating the second piston; and a second outlet configured to exhaust the gases.
