Abstract: An oil supply system for a propeller turbine engine includes a first oil circuit for supplying the turbomachine and a second oil circuit for supplying the propeller gearbox and the high-pressure pump associated with a propeller adjusting device. The two oil circuits are integrated into a common oil tank and connected to one another by means of an oil supply line in the flow direction downstream of the first and the second oil conveying pumps in such a way that a limited oil volumetric flow can flow from the first oil circuit into the second oil circuit, and only in this direction, if the pressure difference between the first and the second oil circuits falls below a certain level in the event of a pressure reduction in the second oil circuit.

Abstract: A burner for difficult to combust gas mixtures, particularly those including exhaust gases of an internal combustion engine, that is preferably intended for the regeneration of particle filter units in the exhaust gas duct of an internal combustion engine, such as a diesel internal combustion engine. For initiating the regeneration of such so-called soot filter units, the burner generates hot combustion gases at the outlet thereof. The burner includes, at a distance from the discharge opening of a fuel injection nozzle, a baffle barrier that extends approximately perpendicular to the center axis of the fuel injection nozzle. This baffle barrier divides the combustion chamber into an energy-rich zone with a gas mixture prepared to be ignitable and a second zone in which the exhaust gas from the internal combustion engine is diverted.
