High-pressure pump arrangement for a combustion engine and method for manufacturing the same
A high-pressure pump arrangement for a combustion engine comprises a high-pressure pump with the first flange, a pump guidance with a second flange. The high-pressure pump is at least partially arranged in the pump guidance and the pump guidance is arranged in the combustion chamber. A first thermally insulating layer is at least partially arranged between the first flange and the second flange.
1. A high-pressure pump arrangement for a combustion engine comprising:
a high-pressure pump having a first flange; and
a pump guidance having a second flange,
wherein the high-pressure pump is at least partially arranged in the pump guidance,
wherein the pump guidance is arranged in the combustion engine, and
wherein a first thermally insulating layer is at least partially arranged between the first flange and the second flange.
2. The high-pressure pump arrangement according to claim 1 , wherein the high-pressure pump comprises a tappet that is at least partially movable within the pump guidance.
3. The high-pressure pump arrangement according to claim 1 , wherein a second thermally insulating layer is at least partially arranged between the second flange and the combustion engine.
4. The high-pressure pump arrangement according to claim 1 , wherein surfaces of the tappet comprise at least partially a third thermally insulating layer.
5. The high-pressure pump arrangement according to claim 1 , wherein an inner surface of the pump guidance comprises at least partially a fourth thermally insulating layer.
6. The high-pressure pump arrangement according to claim 3 , wherein the first thermally insulating layer and the second thermally insulating layer comprise rubber layers.
7. The high-pressure pump arrangement according to claim 1 , wherein the third thermally insulating layer and the fourth thermally insulating layer comprise at least one of ceramic materials and diamond-like carbon.
8. A method for manufacturing a high-pressure pump arrangement for a combustion engine, the method comprising the steps of:
arranging a high-pressure pump with a first flange into a pump guidance with a second flange, such that a first thermally insulating layer is at least partially arranged between the first flange and the second flange; and
arranging the pump guidance with the second flange into the combustion engine.
9. The method according to claim 8 , wherein a second thermally insulating layer is at least partially arranged between the second flange of the pump guidance and the combustion engine.
