Latest Patents

One of Dorsch's latest patents is an arrangement for the control of the charging pressure of an exhaust gas turbocharger. This invention features a turbine that drives the compressor, regulated by a by-pass valve controlled by an electromagnetic timing valve. The control apparatus adjusts the cycle duration based on the deviation from the desired charging pressure of the internal combustion engine. For operational safety, the design includes two control lines with different pressure levels, each connected to a shifting valve that leads to a common control pressure line for the by-pass valve.

Another notable patent is a propulsion aggregate for an aircraft. This invention consists of a multicylinder-injection internal combustion engine and a propeller with adjustable blade pitch. The propeller can be driven directly by the engine or through a speed reduction gear. The internal combustion engine is equipped with a continuously operating fuel injection system, complemented by additional control installations for optimal aircraft operation. The throttle valve, propeller blade pitch, and charging pressure are all adjustable by a common mechanism.
