Abstract
The aim of the invention is to improve the efficiency of an axial-piston motor. To this end, the axial-piston motor comprises at least one compressor cylinder, at least one working cylinder and at least one pressure line guiding the compressed fuel from the compressor cylinder to the working cylinder. A working piston comprising a working rod is provided in the working cylinder, and a compressor piston comprising a compressor rod is provided in the compressor cylinder. The axial-piston motor is characterized in that it at least one of the two rods comprises transverse stiffeners.
Claims18
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;
- and
- wherein at least one control chamber is a component of the pressure-oil circuit.
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;
- and
- wherein the combustion chamber pressure acting on the control piston is compensated by a pressure level present in a control chamber and corresponding to the combustion chamber pressure.
