Axial-piston engine, method for operating an axial-piston engine, and method for producing a heat exchanger of an axial-piston motor

Axial-piston engine with a compressor stage comprising at least one cylinder, with an expander stage comprising at least one cylinder, with at least one combustion chamber between the compressor stage and the expander stage, with at least one component subjected to combustion chamber pressure and with an oil circuit for lubrication, wherein the oil circuit has an engine-oil circuit and a pressure-oil circuit with a pressure level different from the engine-oil circuit.

Axial-piston engine with at least one compressor cylinder, with at least one working cylinder and with at least one pressure line through which compressed combustion agent is conducted from the compressor cylinder via a combustion chamber to the working cylinder, wherein the stream of combustion agent from the combustion chamber to the working cylinder is controlled via at least one control piston, which is driven by a control drive, wherein the control piston, in addition to the force applied by the control drive, is subjected on its side facing away from the combustion chamber to a compensating force directed counter to the combustion chamber pressure.

Axial-piston engine with at least one compressor cylinder, with at least one working cylinder and with at least one pressure line, through which compressed combustion agent is conducted from the compressor cylinder to the working cylinder, wherein the stream of combustion agent from the combustion chamber to the working cylinder is controlled via at least one control piston, which is driven by a control drive, wherein the control piston is situated in a pressure space.

Method for operation of an axial-piston engine with a compressor stage comprising at least one cylinder, with an expander stage comprising at least one cylinder and with at least one combustion chamber between the compressor stage and the expander stage, wherein a stream of combustion agent, under combustion chamber pressure, from the combustion chamber to the cylinder of the expander stage is controlled via at least one control piston and the axial-piston engine has an oil circuit for lubrication, wherein the oil circuit is split into an engine-oil circuit and into a pressure-oil circuit and components of the axial-piston engine subjected to combustion chamber pressure are lubricated by the pressure-oil circuit.
