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.

A method of manufacturing a packing cup for a hyper-compressor is described. The method comprises the following steps:

Packing cups manufacturing

A packing case for a plunger or a piston rod of a reciprocating machine comprises packing cups, each packing cup comprising a body with a hole for the passage of the plunger or rod and a sealing ring seat for housing a sealing ring which slidably bear against the plunger or rod. Packing cups are aligned with each other in series. The packing case comprises lube oil ducts for supplying lube oil from an end of the packing case to the sealing ring seat. Each packing cup comprises sectors, each sector comprising at least lube oil duct portions. The packing cups are positionable to bring, one sector at a time in an activation position where some of the lube oil duct portions of the sector are connected with the lube oil duct portions of an adjacent packing cup to form lube oil ducts. The packing cups are lockable.
