  • Gas compressor and method with improved valve assemblies
    Patent number: 6817846
    Abstract: A gas compressor and method according to which a piston assembly reciprocates in a bore to draw the fluid to be compressed into the bore during movement of the piston unit in one direction and to compress the fluid during movement of the piston unit in the other direction.
    Type: Grant
    Filed: June 13, 2002
    Date of Patent: November 16, 2004
    Assignee: Dresser-Rand Company
    Inventor: Robert Bennitt
  • Compressor and method with an improved inlet and discharge valve arrangement
    Publication number: 20040018106
    Abstract: A gas compressor and method according to which a plurality of inlet valve assemblies are angularly spaced around a bore. A piston reciprocates in the bore to draw the fluid from the valve assemblies during movement of the piston unit in one direction and compress the fluid during movement of the piston unit in the other direction and the valve assemblies prevent fluid flow from the bore to the valve assemblies during the movement of the piston in the other direction. A discharge valve is associated with the piston to permit the discharge of the compressed fluid from the bore.
