  • Patent number: 11788521
    Abstract: A compressor system for receiving a gas fluid and discharging the gas fluid at a higher pressure. The system comprises at least one compressor and at least one piston intensifier associated with each compressor. Each piston intensifier has a double-acting piston, with one piston head reciprocating in an actuation cavity and the other piston head reciprocating in a high pressure cavity. The compressor delivers its output flow to both cavities of the piston intensifier, alternating between below and above their piston heads, to provide both a working (actuation) fluid and a fluid to be compressed and discharged. A return flow from the actuation cavity back to the compressor also alternates to recycle the working fluid.
