Abstract
Systems, devices, and methods of manufacture are provided for a cylindrical compressor with a standardized shell and core. The compressor including a cylindrical cast metal shell having a shell bore extending longitudinally therethrough and configured to receive a cylindrical cast metal core. The core having a core bore extending longitudinally therethrough defining a core bore diameter within a predefined range of diameters and corresponding to a shell bore diameter. The core having an outer diameter configured to provide an interference fit between the core and the shell when the core is disposed within the shell. The compressor including a plurality of valve assemblies extending through the shell and the core so as to interface a valve of the valve assembly with the core bore and further including cylinder head coupled to the shell, a piston rod assembly configured within the core bore, and a packing case coupled to the core.
