Definitions
- the invention relates to a compressor and a vehicle compressed air system with such a compressor, in particular for rail vehicles.

- the heat flow reduction device which reduces the heat flow from a component connected to the intake chamber to the intake air in the intake chamber, can prevent the air in the intake chamber from being heated excessively. If further additionally or alternatively a heat flow reduction device is provided, which reduces the heat flow from the compressed air in the outlet chamber to a component connected to the outlet chamber wall, the effect of preventing excessive heating can be achieved alternatively or to a greater extent.
- the heat flow reduction device has at least parts of the inlet chamber wall and the outlet chamber wall which are designed such that a first air gap is formed between two opposite surfaces of the outlet chamber wall and the inlet chamber wall.
- the intake chamber and the exhaust chamber are provided in a common housing, such as a cylinder head with a common intake chamber wall and exhaust chamber wall, which is then one and the same wall, the large heat flow from the exhaust chamber to the intake chamber can be strong be reduced.
- the inlet chamber wall and the outlet chamber wall are designed as separate components.
- the separation of the inlet chamber and the outlet chamber ensures a reduction in the heat flow and the respective components can be optimally designed since their shapes can be individually adapted to a suitable shape of the inlet and outlet chambers.
- the inlet chamber wall and the outlet chamber wall are formed integrally and the first air gap is formed such that the inlet chamber wall and the outlet chamber wall are at least partially spaced from one another.
- This configuration enables a reduction in components and simplified assembly.

- the provision of the second air gap reduces the first contact area between the inlet chamber wall or the outlet chamber wall on the one hand and the valve plate on the other hand, so that the heat flow from the valve plate to the inlet chamber wall or from the outlet chamber wall to the valve plate is also reduced in order to prevent heat transfer from the air in of the outlet chamber to the air in the inlet chamber.
- the compressor has a compression chamber housing, which is designed to compress the intake air therein, and the heat flow reduction device has a second thermal insulation material between at least one of the inlet chamber wall and the outlet chamber wall on the one hand and the compression chamber housing on the other.
