- Piston pump in particular high-pressure fuel pump prior art
- the invention relates to a piston pump according to the preamble of claim 1.
- Fuel quantity can be promoted in a fuel tank or fuel rail under a particular desired pressure.
- high-pressure fuel pumps are designed as piston pumps.
- a rotational movement is converted into a stroke movement by a piston seated radially on a cam or balance shaft. Due to the stroke of the piston, the fuel can be compressed in a working space of the high-pressure fuel pump and conveyed to a high-pressure side of the high-pressure fuel pump or the fuel system.
- essential elements of such high-pressure fuel pumps are massive
- the invention has the advantage that a weight of a high pressure fuel pump can be reduced and manufacturing costs can be reduced.
- the piston pump according to the invention makes it possible that elements within the piston pump can be better hydraulically connected to each other. This can result in lower suction losses of the piston pump and a better filling of a working space of the piston pump. As a result, a vapor formation can be reduced within the piston pump, which may result in a lower risk of seizure.
- a pre-pressure of the piston pump according to the invention can be lowered.
- the piston pump encloses a comparatively large
- Piston pump can be steamed. Furthermore, a substantially uniform heating of a piston and a cylinder liner of the piston pump takes place during operation. This also causes a decreased tendency to
- the piston pump according to the invention can be produced with a smaller proportion of Zerspanungsherstellariaen. Elements of the piston pump can often be designed as relatively simply produced turned parts or as sheet-deep-drawn parts.

- the at least one coupling element is a tubular sleeve.
- tubular sleeve includes according to the invention that the coupling element in the axial direction may also comprise variously executed sections.

- the cylinder liner is welded to the coupling element.
- welds by means of capacitor discharge welding (KE welding) can be produced, resulting in a durable and very cost-effective connection.
- Joining techniques include laser welding or soldering. Even a compression is conceivable.
- the valve device comprises a quantity control valve and / or an outlet valve.
- the quantity control valve and the outlet valve are in each case arranged on or in a separate designed as a tubular sleeve coupling element.
- the piston pump comprises a pot-shaped housing with a jacket portion, which with the at least one

- the connection can also be made by welding seams, in particular by means of a capacitor discharge welding process (KE welding).
- KE welding capacitor discharge welding process
- the cup-shaped housing of the piston pump according to the invention can be designed as a deep-drawn part, which can result in a comparatively low weight and low production costs. Nevertheless, the pot-shaped housing is robust enough for the comparatively rough operation of a high-pressure fuel pump.
- the jacket portion of the housing is connected, for example, with a respective axial end portion of the coupling element.
- the cup-shaped housing defines a cavity which is hydraulically connected to an inlet opening of the piston pump.

- the flange portion is preferably arranged at an end portion of the cup-shaped housing of the piston pump, which one of the
- Piston pump bearing mounting structure of the internal combustion engine is facing. Therefore, not only the cup-shaped housing can be closed fluid-tight by means of the flange portion, but the flange portion can also be used as an abutment for the piston spring and as a holder for the piston seal. As a result, the piston pump can be produced in a particularly simple and cost-effective manner.
- the cup-shaped housing and / or the flange portion is carried out using drawn and / or embossed and / or bent sheets or as injection-molded parts.
- the cup-shaped housing or the flange section can be particularly simple and lightweight and also
- an axial end portion of the cylinder liner is designed as inlet nozzle.
- the inlet nozzle is designed in the direction of a longitudinal axis of the cylinder liner.
- the inlet connection piece can be connected directly to an axial end section ("front side") of the cup-shaped housing, for example by means of welding.
- the design of the inlet nozzle can result in cost advantages and a reduction in the number of parts of the piston pump.
- there are also functional advantages since the stability of the piston pump according to the invention can be increased. In particular, a load on the welds between the shell portions of the cup-shaped housing and the coupling elements can be significantly reduced, whereby the fatigue strength of the piston pump can be improved.
- the inlet nozzle is connected by at least one radial bore with the cavity.
- the cavity formed by the cup-shaped housing can advantageously be used for hydraulic pressure damping in a simple, but at the same time effective manner, which means
