Definitions
- the invention relates to a piston pump, in particular High pressure fuel pump, with a housing and with at least one attached to the side of the housing Component.
- a piston pump of the type mentioned is on the market known from here. For example, it comes with Fuel systems with direct fuel injection for Commitment. In such systems, the fuel is from a high pressure pump compressed to a very high pressure and promoted to a fuel rail.
- the high pressure piston pump includes a cylinder in which a piston is reciprocally received. at this movement of the piston is in a work space absorbed fuel compressed.
- the fuel enters the work area via an inlet connection, and from the high-pressure piston pump to the fuel manifold via an outlet connection.
- the two sockets are on that Cylinder, which has a round outer cross section, screwed into side holes. The outer surface of the Cylinder is turned flat in the area of the bores.
- the housing in the known high-pressure piston pump is made Steel made. This is necessary to the high pressure piston pump also use with such fuels can, which contain ethanol. Starting from one such high pressure piston pump it is the job of present invention to reduce its manufacturing costs.
- This task is the beginning of a piston pump mentioned type in that the housing a polygonal cross-sectional shape with at least sections straight side surfaces, and that at least one Component arranged in the area of a straight side surface is.
- the side faces are at least approximately the same size. This increases the Flexibility of the case, because basically every component can be arranged on each side surface.
- the Housing in cross section the shape of a symmetrical Polygon, in particular a hexagon.
- a symmetrical polygons are the opposite Side surfaces arranged parallel to each other. This facilitates the positioning of the housing during the Processing.
- the support of forces that during processing or during Attaching components to a side surface on this must be applied in this embodiment the piston pump simplified.
- a hexagon offers six Side surfaces a sufficient number of possible Connection points for components, at the same time low manufacturing costs.
- the invention then has a particularly advantageous effect, if the housing is made of stainless steel.
- the Machining stainless steel is comparatively expensive and complex and time-consuming. Since in the invention Piston pump elaborate processing steps are eliminated can, especially when using stainless steel Significantly reduced costs.
- the Housing is made from a standard polygonal profile.
- Such, usually drawn starting materials are inexpensive, so that with this configuration the Piston pump according to the invention the manufacturing costs low are.
- the Piston pump according to the invention provided that at least a component arranged on a side surface Pressure sensor is.
- the straight side surfaces of the Piston pump according to the invention are particularly suitable for Attachment of a commercially available pressure sensor. Already this significantly reduces costs.
- Such components which one Have fluid connection, and such components, which have an electrical connection, at least one another roughly opposite. This facilitates assembly as well the sensible arrangement of the fluid or electrical cables.
- an internal combustion engine carries this overall Reference numeral 10. It includes a fuel system 12, too which includes a fuel tank 14. For this promotes a pre-feed pump 16 to a high-pressure piston pump 18. For this purpose, it has an inlet connector 20. About one The outlet connection 22 includes the high-pressure piston pump 18 a fuel rail 24 connected in which the Fuel is stored under high pressure. To them are several fuel injectors 26 connected, the combustion chambers assigned directly to the fuel in them 28 inject.
- the high-pressure piston pump 18 is shown directly in FIG. 1 unspecified way of a Camshaft of the engine 10 driven.
- an electromagnetic Actuator 30 available, which on a in Figure 1 invisible inlet valve of the high pressure piston pump 18 acts.
- the whole from electromagnetic actuator 30 and Inlet valve of the high pressure pump piston pump 18 will also referred to as a volume control valve.
- the high-pressure piston pump 18 includes an elongated housing 34 made of stainless steel is made and in which a cylinder sleeve 36 and a received in this reciprocating piston 38 are. As can be seen in particular from FIG. 2, this is Housing 34 from a commercial drawn Hexagon profile 39, which is a total of six in Has essentially straight side surfaces 40a to 40f. Alternatively, the straight side surfaces could also be used Turning.
- the cylinder liner 36 and the Pistons 38 are arranged in a blind bore 42 which in the central axis of the hexagonal profile 39.
- the Blind bore 42 and piston 38 limit one Work space 44.
- a stepped bore 46 is in the side surface 40a introduced, which over a not shown Inlet valve can communicate with the work space 44 and into which the inlet connector 20 is inserted. He is with that Housing 34 welded in 48.
- the next but one side surface 40c of the Hexagon profile 39 is also a stepped bore 50 available, in which the outlet port 22 is inserted. He is with a weld seam 52 to the housing 34 welded.
- the stepped bore 50 is also a Exhaust valve 54 pressed.
- the stepped bore 50 can also communicate with the work space 44.
- the next but one side surface 40e again introduced a stepped bore 56, in which the electromagnetic actuator 30 and (not visible) the inlet valve is inserted.
- FIGS. 2 and 3 It is readily apparent from FIGS. 2 and 3 that through the shape of the housing 34 as a hexagonal profile 39 the straight side surfaces 40a to 40f the connection of Components, such as the two connecting pieces 20 and 22 and the electromagnetic actuating device 30, is significantly simplified.
- the introduction of the corresponding stepped bores 46, 50, and 56 is in the straight side surfaces 40a, 40c, and 40e simply and with high precision possible.
- FIG. 4 An alternative embodiment of a high pressure piston pump 18 is shown in FIG. 4. Such wear Elements and areas that have equivalent functions Elements and areas related to the figures 2 and 3 have illustrated embodiment, the same reference numerals. They are not in detail again explained.
- the inlet connector 20 is not on the side surface 40a, but on the side surface 40b, that is, directly adjacent to the outlet port 22. Furthermore, in the side surface 40f introduced a threaded bore 58 in which is screwed in a pressure sensor 60.
- the Threaded bore 58 communicates with the stepped bore 46, in the inlet connector 20 is attached.
- the pressure sensor 60 is a commercial part, which due to the presence the straight side surface 40f on the housing 34 of the High-pressure piston pump 18 attached and for example over an O-ring 61 can be sealed. By direct Attachment of the pressure sensor 60 to the high pressure piston pump 18 are additional installations in the Line area between the prefeed pump 16 and the High pressure piston pump 18 is not required.
