- the guide sleeve is connected to the housing recess via a material-fit connection.
- a cohesive connection of the components housing and Füh ⁇ tion sleeve of the high-pressure fuel pump is now proposed.
- stresses and deformations on these components can be avoided, resulting in a reduction of defects in the high-pressure fuel pump.
- a guide gap is provided between the guide sleeve and the pump piston guided therein, which is filled during operation with a fuel so as to act as a lubricant during the movement of the pump piston in the guide sleeve.
- the material connection to a Kle ⁇ Bever bond comprising an adhesive.
- Adhesives can advantageously be easily mounted in the housing recess or on the guide sleeve, so that the guide sleeve can be connected by a particularly simple method with the housing.
- the adhesive is thermally stable up to a temperature of at least 180 ° C.
- the adhesive Since frequent high temperatures between 150 ° C and 180 ° C may occur during operation of the high- pressure fuel pump, it is advantageous if the adhesive does not soften in this temperature range and the connection between the housing and guide sleeve does not dissolve. Therefore, it is advantageous if the adhesive is thermally stable up to a temperature of at least 180 ° C and does not soften.
- the adhesive in fuels, in particular ⁇ special in gasoline and / or diesel, insoluble.
- the adhesive does not dissolve due to the contact with fuel and thus the connection between housing and guide sleeve is not released.
- the guide sleeve is arranged in a recess of the housing recess, which extends adjacent to a pressure chamber of the high-pressure fuel pump to a space at the other end of the pump piston.
- the recess preferably has a return end face, on which a guide sleeve end face of the guide sleeve is arranged, wherein the adhesive between the return end face and the guide sleeve end face is arranged.
- the recess has a return side surface, on which a guide sleeve side surface is arranged, wherein the adhesive between the return side surface and the guide sleeve side surface is arranged.
- the adhesive is arranged not only in the region of the end surfaces, but preferably also in the region of the side surfaces, a preferably even better sealing of the joint against fuel leakage arises.
- the cohesive connection can have a welded connection.
- the welded connection may be a friction-welded connection, ie a welded connection, in which the guide sleeve has been connected to the housing recess by advantageously rubbing together a guide sleeve surface and a housing recess wall.
- Welded connections have the advantage that they are particularly strong and tight against fuel leakage.
- the cohesive connection can also have a region in which the guide sleeve is vulcanized onto the housing recess.
- a sealing arrangement is provided between the housing recess and between the guide sleeve.
- An additional sealing arrangement together with the cohesive connection, advantageously prevents the occurrence of fuel leakage in the joint between the housing recess and the guide sleeve.
- the guide sleeve is formed of a material having a greater hardness than the material of the housing.
- the high-pressure fuel pump can be designed more cost-effective, since only the area which is subject to wear by movement of the pump piston, namely the guide sleeve is formed of the higher quality material, while the housing is formed of a standard material, which is less expensive.
- the guide sleeve may be formed of a hardened stainless steel, while the housing is formed of a normal stainless steel.
