Definitions
- the invention relates to a piston pump, in particular high-pressure fuel pump, with a housing and with at least one laterally attached to the housing component.
- a piston pump of the type mentioned is known from the market. It is used, for example, in fuel systems with direct fuel injection. In such systems, the fuel is compressed by a high pressure pump to a very high pressure and delivered to a fuel rail.
- the high pressure piston pump includes a cylinder in which a piston is reciprocably received. During this movement of the piston, fuel taken up in a working space is compressed. The fuel enters the working space via an inlet port, and from the high pressure piston pump to the fuel manifold via an outlet port.
- the two nozzles are on the cylinder, which has a round outer cross-section, screwed into lateral holes. The lateral surface of the cylinder is turned flat in the area of the holes.
- the housing in the known high-pressure piston pump is made of steel. This is necessary in order to use the high-pressure piston pump with such fuels, which are ethanolhaltig. Starting from such a high-pressure piston pump, it is the object of the present invention to reduce their production costs.
- a component to be mounted on the housing can be easily arranged.
- the straight side surfaces provide ideal interfaces for most types of components to be attached.
- An additional processing of the side surfaces for the integration of a component can be omitted. This lowers the manufacturing costs of the housing.
- tools which introduce radially extending bores into the housing or to process existing boreholes there, can be positioned more accurately and faster on the straight side surfaces, which increases the manufacturing quality of the piston pump according to the invention.
- At least one component arranged on a side surface is a pressure sensor.
- the straight side surfaces of the piston pump according to the invention are particularly well suited for mounting a commercially available pressure sensor. Already this reduces the Cost considerably.
- the side surfaces are at least approximately the same size. This increases the flexibility of the housing since basically any component can be placed on each side surface.
- the housing has the shape of a symmetrical polygonal cross-section, in particular of a hexagon, in cross-section.
- the opposing side surfaces are arranged parallel to each other. This facilitates the positioning of the housing during processing.
- the support of forces that must be applied during processing or during the attachment of components on a side surface on this is simplified in this embodiment of the piston pump.
- a hexagon offers with six side surfaces a sufficient number of possible connection points for components, at the same time still low production costs.
- the invention has an effect if the housing is made of stainless steel.
- the processing of stainless steel is relatively expensive and time-consuming and consuming. Since in the piston pump according to the invention consuming processing steps omitted especially when using stainless steel, the costs are significantly reduced.
- the housing is made of a round profile, from which the straight side surfaces are worked out.
- Round profiles are available in a wide variety of diameters and material qualities, which facilitates the production of a piston pump which is tailored precisely to the specific requirements of the particular application.
- the housing is made of a standard polygonal profile.
- Such, usually drawn starting materials are inexpensive, so that in this embodiment of the piston pump according to the invention, the production costs are low.
- those components which have a fluid connection and those components which have an electrical connection, at least approximately opposite each other. This facilitates the assembly and the sensible arrangement of the fluid or electrical lines.
- an internal combustion engine carries the reference numeral 10. It comprises a fuel system 12 to which a fuel tank 14 belongs.
- a prefeed pump 16 conveys to a high-pressure piston pump 18.
- this has an inlet pipe 20.
- the high pressure piston pump 18 is connected to a fuel rail 24 in which the fuel is stored under high pressure.
- a plurality of fuel injectors 26 are connected, which inject the fuel directly into them associated combustion chambers 28.
- the high pressure piston pump 18 is placed directly on in FIG. 1 not shown manner driven by a camshaft of the internal combustion engine 10.
- an electromagnetic actuator 30 is present, which on a in FIG. 1 invisible inlet valve of the high-pressure piston pump 18 acts.
- the entirety of electromagnetic actuator 30 and inlet valve of the high-pressure pump-piston pump 18 is also referred to as a quantity control valve.
- the high-pressure piston pump 18 comprises an elongated housing 34 which is made of stainless steel and in which a cylinder liner 36 and a reciprocating piston 38 are received in this.
- the housing 34 is made of a commercial drawn hexagonal profile 39 having a total of six substantially straight side surfaces 40a to 40f. Alternatively, the straight side surfaces could also be made by turning.
- the cylinder liner 36 and the piston 38 are arranged in a blind bore 42 which extends in the central axis of the hexagonal profile 39.
- the blind bore 42 and the piston 38 define a working space 44th
- a stepped bore 46 is introduced, which can communicate via an inlet valve, not shown, with the working space 44 and in which the inlet port 20 is inserted. It is welded to the housing 34 in FIG. 48.
- a stepped bore 50 is provided, in which the outlet port 22 is inserted. He is welded to the housing 34 with a weld 52.
- an outlet valve 54 is pressed. The stepped bore 50 can also communicate with the workspace 44.
- a stepped bore 56 is again introduced, in which the electromagnetic actuator 30 and (not visible), the inlet valve are used.
- FIG. 4 An alternative embodiment of a high pressure piston pump 18 is shown in FIG. 4 shown.
- carry such elements and areas which equivalent functions to elements and areas of related to the Figures 2 and 3 explained embodiment, have the same reference numerals. They are not explained again in detail.
- the inlet nozzle 20 is not on the side surface 40a, but on the side surface 40b, ie immediately adjacent to the outlet 22, respectively. Further, in the side surface 40 f, a threaded bore 58 is introduced, in which a pressure sensor 60 is screwed. The threaded hole 58 communicates with the stepped bore 46, in which the inlet port 20 is fixed. By the pressure sensor 60, therefore, the pressure in a low pressure region (without reference numeral) of the fuel system 12 can be detected.
- the pressure sensor 60 is a commercial part, which can be easily attached to the housing 34 of the high-pressure piston pump 18 due to the presence of the straight side surface 40 f and sealed, for example, via an O-ring 61. Due to the direct attachment of the pressure sensor 60 to the high-pressure piston pump 18, additional installations in the line area between the prefeed pump 16 and the high-pressure piston pump 18 are not required.
- an electrical line which is connected to a socket 62 of the pressure sensor 60, be performed together with an already existing electrical line, which is connected to a socket 64 of the electromagnetic actuator 30.
- FIG. 4 is very clear that when using a hexagonal profile 39 for the housing 34 on the one hand, the electrical components 30 and 60 and on the other hand connected to the fluid lines components 20 and 22 can be grouped in a simple manner opposite. This simplifies the corresponding wiring again.
