Method for operating an axial piston motor, and axial piston motor
First Claim
Patent Images
1. A method for operation of an axial piston motor comprising:
- continuously combusting fuel and compressed combustion medium in a combustion chamber to produce working medium;
delivering the working medium to successive working cylinders;
drawing the combustion medium into compressor cylinders by way of compressor inlet valves;
moving working pistons back and forth in the working cylinders to drive a power take-off and compressor pistons back and forth in the compressor cylinders to produce the compressed combustion medium;
delivering the compressed combustion medium to the combustion chamber by the compressor cylinders by way of compressor outlet valves;
closing at least one of the compressor outlet valves with positive control via a valve drive producing a closing force affecting a closure part of the at least one of the compressor outlet valves; and
opening the at least one of the compressor outlet valves by way of a removal of the closing force of the valve drive and by way of a compressor pressure that builds up in the respective compressor cylinder.

Abstract
In an axial piston motor in which fuel and compressed combustion medium are continuously burned in a combustion chamber so as to be turned into the working fluid and successively be delivered to working cylinders, at least one of the compressor discharge valves is closed in a positively controlled manner and is opened by a compressor pressure building up in the respective compressor cylinder.

10. An axial piston motor
having a combustion chamber that combusts continuously compressed combustion medium and fuel to produce working medium, having working cylinders that are connected with the combustion chamber by connections that can open and close cyclically, having working pistons moving back and forth in the working cylinders, having compressor cylinders in which compressor pistons move back and forth, which compressor pistons are driven by the working pistons, having at least one combustion medium feed line that leads from compressor outlet valves of the compressor cylinders to the combustion chamber, and having a valve drive configured to exert a positive control acting on a closure part of at least one of the compressor outlet valves in an opening direction, the closure part opening away from the compressor cylinder, wherein the closure part interacts with the valve drive and opens counter to a restriction arrangement, and wherein the valve drive releases the closure part in the opening direction so that a compressor pressure that builds up in the compressor cylinder is able to open the at least one of the compressor outlet valves and/or exerts the positive control acting on the closure part only in the opening direction.
