A MODULAR MACHINE

摘要

A machine which may be an internal combustion engine, compressor, pump or other machine with reciprocating pistons in which significant parts are manufactured with a uniform cross section appropriate to extrusion or continuous casting. Parts may be manufactured in the above manner which are designed to allow the assembly of machines of arbitrary size and capacity using many similar fixed and moving components from the same elementary production facility. Machines in which the valves can be pistons valves in bores containing the main machine pistons with a flat or low profile head, resulting in a compact machine. In addition, methods of manufacture which allow sections from which components are to be made to be treated or processed in bulk. Further methods of manufacture embodying features which reduce the number of threaded holes required in the machine, reduce the weight of the machine, reduce the labour and cost of assembly and reduce the capital costs of manufacturing facilities.
