  • Variable volume clearance pocket for a reciprocating compressor cylinder
    Patent number: 8430646
    Abstract: A controllable variable volume clearance pocket for reciprocating compressor cylinders is disclosed. The invention includes a device for varying the clearance volume of a variable volume clearance pocket in a controlled manner. The device can be used repeatedly to change the compressor cylinder clearance volume as required to control compressor capacity and power required from the compressor driver. The device is typically mounted on the outer or head end of a reciprocating compressor cylinder, but can also be scaled and configured for use either in conjunction with a variable clearance volume unloader operating over a reciprocating compressor valve pocket or a special port in a reciprocating compressor body.
