Stephen J. Kathmann is a notable inventor based in Quincy, Illinois. He has made significant contributions to the field of engineering, particularly in the design of gas compressors. His innovative approach has led to the development of a unique patent that enhances the efficiency of gas compression systems.

Latest Patents

Kathmann holds a patent for a "Multistage helical screw compressor with liquid injection." This invention involves a two-stage liquid injected helical screw gas compressor that features a bypass line with a check valve between the compressor stages. This design allows for the delivery of compressed gas from the first stage directly to the compressed gas receiver and liquid reservoir. The bypass of gas to the reservoir at startup ensures the pressurization of the reservoir and facilitates early flow of liquid to the compression chambers. As the working pressure in the second stage discharge line increases above the first stage discharge pressure, the check valve closes, directing all flow from the first stage through the second stage compression chamber.
