Latest Patents
Gerald L Donnellan holds 1 patent for his invention of an exhaust brake valve. This patent illustrates a valve positioned between a divided section exhaust manifold of an internal combustion engine and the divided flow entry to a turbine wheel of a turbocharger. The valve features a closure member that can be displaced between two positions. In the second position, it allows separate but free flow from the exhaust manifold sections to the turbine. When in the first position, the valve blocks flow to the turbine while interconnecting the exhaust manifold sections. This design enables the engine to act like a compressor, providing a retarding effect while minimizing peak pressure pulses to prevent engine valve bounce.
