Abstract

The fuel feed line arrangement for a fuel injection nozzle (12) inserted in the cylinder head (10) of an internal combustion engine has a pipe union (20), which passes through the cylinder head (10) of the internal combustion engine transversely to the injection nozzle (12) and is clamped with its outlet end (29) against a lateral seating face (16) on the injection nozzle (12) by means of a retaining screw (27). In order to ensure ease of assembly when the injection nozzle (12) is misaligned, the pipe union (20) has a spherical taper (29) on its outlet end and a spherical shoulder (26) in the middle area, against which the hollow retaining screw (27) presses. The admission-side end section (22) of the pipe union (20) projects beyond the retaining screw (27) and the cylinder head (10) and has an external thread (31) on to which a union nut (32) is screwed pressing the feed pipe (35) with a tapered connection piece (34) against the pipe union (20). <IMAGE>

Description

Die Erfindung geht aus von einer Kraftstoffzuleitungseinrichtung für eine in einem Zylinderkopf einer Brennkraftmaschine eingesetzten Einspritzdüse nach der Gattung des Anspruchs 1. Bei einer bekannten Kraftstoffzuleitungseinrichtung dieser Gattung sind der Rohrstutzen und auch das Anschlußstück des Zulaufrohrs vollständig im Durchgang des Zylinderkopfs untergebracht. Diese Anordnung gleicht wohl einen Versatz des Düsenhalters der Einspritzdüse im Zylinderkopf aus, ihre Montage ist jedoch nur zusammen mit dem von der Einspritzpumpe herangeführten Zulaufrohr möglich.The invention is based on a fuel supply device for an injection nozzle used in a cylinder head of an internal combustion engine according to the preamble of claim 1. In a known fuel supply device of this type, the pipe socket and also the connecting piece of the inlet pipe are completely accommodated in the passage of the cylinder head. This arrangement probably compensates for an offset of the nozzle holder of the injection nozzle in the cylinder head, but it can only be installed together with the inlet pipe brought up by the injection pump.

Eine besonders einfach zu montierende Kraftstoffzuleitungseinrichtung ergibt sich, wenn diese gemäß dem kennzeichnenden Teil des Anspruchs 1 ausgestaltet ist, so daß die Einspritzdüse und der Rohrstutzen gleichzeitig montiert werden können und davon unabhängig das Druck- oder Zulaufrohr zu einem späteren Zeitpunkt, vorzugsweise beim Anschließen der Einspritzpumpe, in einfacher und übersichtlicher Weise angeschlossen werden kann.A particularly easy-to-assemble fuel supply device results if it is designed in accordance with the characterizing part of claim 1, so that the injection nozzle and the pipe socket can be installed simultaneously and, independently of this, the pressure or supply pipe at a later point in time, preferably when the injection pump is connected , can be connected in a simple and clear manner.

Wenn außerdem gemäß Anspruch 3 im Bund des Rohrstutzens ein Dichtring angeordnet ist, der vorzugsweise im Schwenkpunkt des Rohrstutzens liegt, ist eine völlig dichte Anordnung gegeben. Ferner ist es vorteilhaft, gemäß Anspruch 4 im Rohrstutzen ein Stabfilter anzuordnen.If, in addition, a sealing ring is arranged in the collar of the pipe socket, which is preferably located in the pivot point of the pipe socket, a completely sealed arrangement is provided. Further it is advantageous to arrange a rod filter in the pipe socket according to claim 4.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, die einen Teil eines Zylinderkopfes einer Brennkraftmaschine und eine Kraftstoffzuleitungseinrichtung für eine Einspritzdüse im Schnitt zeigt, und wird im folgenden näher erläutert.An embodiment of the invention is shown in the drawing, which shows part of a cylinder head of an internal combustion engine and a fuel supply device for an injection nozzle in section, and is explained in more detail below.

In einem Zylinderkopf 10 einer Brennkraftmaschine ist in einer zum Brennraum führenden Bohrung 11 eine Einspritzdüse 12 eingesetzt, deren Düsenhalter 13 von einer Klaue 14 ortsfest gehalten wird. Zum Zuführen von Kraftstoff hat der Düsenhalter 13 einen seitlich offenen Zulaufkanal 15, in dem eine zum Umfang des Düsenhalters 13 offene Bohrung mit einer kegeligen Sitzfläche 16 angebracht ist. In Ausrichtung zu dieser Sitzfläche 16 ist im Zylinderkopf 10 ein Durchgang in Form einer gestuften Bohrung 17 angeordnet, die ein Rohrstutzen 20 durchsetzt.In a cylinder head 10 of an internal combustion engine, an injection nozzle 12 is inserted in a bore 11 leading to the combustion chamber, the nozzle holder 13 of which is held stationary by a claw 14. For supplying fuel, the nozzle holder 13 has a laterally open inlet channel 15, in which a bore with a conical seat surface 16 is made open to the periphery of the nozzle holder 13. In alignment with this seat surface 16, a passage is arranged in the cylinder head 10 in the form of a stepped bore 17 which passes through a pipe socket 20.

Der Rohrstutzen 20 hat eine axiale Bohrung 21 mit einer Erweiterung 22 im einlaufseitigen Endabschnitt 23, in der ein an sich bekanntes Stabfilter 24 eingesetzt ist. Etwa in der Mitte seiner Längserstreckung hat der Rohrstutzen 20 einen Bund 25 mit einer balligen Schulter 26, an der eine in die Erweiterung 18 der Bohrung 17 eingeschraubte Überwurfschraube 28 angreifend den Rohrstutzen 20 gegen den Düsenhalter 13 spannt. Um einen dichten Anschluß auch bei axialem Versatz des Düsenhalters 13 sicherzustellen, hat der Rohrstutzen 20 an seinem auslaufseitigen Endabschnitt einen balligen Kegel 29, der gegen die kegelige Sitzfläche 16 des Düsenhalters 13 gespannt ist.The pipe socket 20 has an axial bore 21 with an extension 22 in the inlet-side end section 23, in which a rod filter 24 known per se is inserted. Approximately in the middle of its longitudinal extension, the pipe socket 20 has a collar 25 with a spherical shoulder 26, on which a union screw 28 screwed into the extension 18 of the bore 17 engages the pipe socket 20 against the nozzle holder 13. In order to ensure a tight connection even when the nozzle holder 13 is axially offset, the pipe socket 20 has a spherical cone 29 at its outlet-side end section, which is clamped against the conical seat surface 16 of the nozzle holder 13.

Der zulaufseitige Endabschnitt 23 des Rohrstutzens 20 ragt aus der Bohrung 17 im Zylinderkopf 10 vor und trägt ein Außengewinde 31. Auf dieses ist eine Überwurfschraube 32 aufgeschraubt, die über eine Scheibe 33 ein kegeliges Anschlußstück 34 an einem Zulaufrohr 35 gegen eine konische Sitzfläche 36 am Einlaß der Bohrung 21 bzw. Erweiterung 22 drückt. Ein in einer Umfangsnut 41 des Bundes 20 eingelegter O-Ring 40, der mit seiner Außenseite an der Wand der Bohrung 17 anliegt, dichtet den den Rohrstutzen 20 umgebenden Ringspalt nach außen ab.The inlet-side end section 23 of the pipe socket 20 protrudes from the bore 17 in the cylinder head 10 and carries an external thread 31. A union screw 32 is screwed onto this, which, via a washer 33, a conical connecting piece 34 on an inlet pipe 35 against a conical seat surface 36 at the inlet the bore 21 or extension 22 presses. An O-ring 40 inserted in a circumferential groove 41 of the collar 20, the outer side of which rests against the wall of the bore 17, seals the annular gap surrounding the pipe socket 20 to the outside.
