David B Meisner is an inventor based in Carol Stream, Illinois, with an impressive portfolio of three patents under his belt. His latest patented inventions are the oil pickup tube assembly and the hydraulic fuel system.
The oil pickup tube assembly is a unique apparatus and method for mounting a flange to an oil pickup tube. It employs a bracketed flange mounting system that includes a flange with a flange extension connected to a bracket that is attached to the oil pickup tube between its two ends. This design allows the bracketed flange mounting to connect to the engine crankcase or oil pump inlet the same way as prior assemblies do, without requiring any retooling of any other part of the engine. This makes it an economical and efficient solution for mounting flanges to oil pickup tubes.
The hydraulic fuel system, on the other hand, is a sophisticated invention that integrates and internally mounts an oil circuit to provide high pressure in a hydraulically operated electronically controlled fuel injector fuel system. The system includes an internally mounted high-pressure pump in a pump housing in the crankcase, which is directly connected to internally routed high-pressure oil rails. There is also an integrated low-pressure oil reservoir in the crankcase that comprises a low-pressure oil cooler and reservoir. Additionally, a high-pressure pump filter covers a high-pressure pump inlet feed passage to prevent debris from passing into the high-pressure oil pump and other components on the high-pressure oil circuit.
