Description

Die Erfindung betrifft eine Kraftstofführung im Zylindergehäuse einer Brennkraftmaschine mit den im Oberbegriff des Patentanspruchs 1 angegebenen Merkmalen.The invention relates to a fuel guide in the cylinder housing of an internal combustion engine with the features specified in the preamble of claim 1.

Aus der DE 43 26 162 C1 ist eine derartige Kraftstofführung im Zylindergehäuse einer mehrzylindrigen Brennkraftmaschine bekannt, welche aus einem durchgehenden Längskanal als Kraftstoffvorlauf sowie aus von dem Längskanal abzweigenden Zuführkanälen besteht. Jeder Zuführkanal mündet in einer im Zylindergehäuse angeordneten Aufnahmebohrung, in der eine dem entsprechenden Zylinder zugeordnete Steckpumpe steckt. Die Steckpumpe ist in Höhe der Mündungsstelle mit einer mit dem Zuführkanal verbundenen Ringnut versehen.Such a fuel guide in the cylinder housing of a multi-cylinder internal combustion engine is known from DE 43 26 162 C1, which consists of a continuous longitudinal channel as a fuel feed and of supply channels branching off from the longitudinal channel. Each feed channel opens into a receiving bore arranged in the cylinder housing, in which a plug-in pump assigned to the corresponding cylinder is inserted. The plug-in pump is provided at the mouth with an annular groove connected to the feed channel.

Der Erfindung liegt die Aufgabe zugrunde, eine das Zylindergehäuse und jede Steckpumpe verbindende einfache Kraftstofführung zu schaffen, durch die eine aufwandarme Lagefixierung der Steckpumpe in der Aufnahmebohrung im Zylindergehäuse erreichbar ist. Die Kraftstofführung soll insbesondere für Steckpumpen mit Magnetventilsteuerung geeignet sein.The invention has for its object to provide a simple fuel guide connecting the cylinder housing and each plug-in pump, by means of which the position pump of the plug-in pump can be fixed in the receiving bore in the cylinder housing with little effort. The fuel guide should be particularly suitable for plug-in pumps with solenoid valve control.

Die Aufgabe wird bei einer gattungsgemäßen Kraftstofführung durch die im Kennzeichen des Patentanspruches 1 angegebenen Merkmale gelöst.The object is achieved in a generic fuel guide by the features specified in the characterizing part of claim 1.

In den Unteransprüchen sind noch förderliche Weiterbildungen der Erfindung angegeben.Further advantageous developments of the invention are specified in the subclaims.

Durch die besondere Ausbildung der Kraftstofführung im Bereich der Trennfläche zwischen dem Zylindergehäuse und dem obenliegenden Pumpengehäuseteil der Steckpumpe ergibt sich neben einer einfachen Lagesicherung der Steckpumpe in der Aufnahmebohrung auch eine abdichtsichere Kraftstoffleitungsverbindung.The special design of the fuel guide in the area of the separating surface between the cylinder housing and the upper part of the pump housing of the plug-in pump results in a simple securing of the position of the plug-in pump in the receiving bore as well as a sealed fuel line connection.

Gleichzeitig zur Lagefixierung der Steckpumpe wird auch ein einfacher Steckanschluß für die Kraftstoffversorgung der Steckpumpe erzielt.Simultaneously with the positional fixing of the plug-in pump, a simple plug-in connection for the fuel supply of the plug-in pump is also achieved.

Außerdem wird durch die besondere Lage der Hülse, die einerseits im Zylindergehäuse und andererseits im freiliegenden Pumpengehäuseteil steckt, der die Hülse umgebende Abdichtring gegen die anliegenden sehr hohen Kraftstoffdrücke geschützt.In addition, the special position of the sleeve, which is on the one hand in the cylinder housing and on the other hand in the exposed pump housing part, protects the sealing ring surrounding the sleeve against the very high fuel pressures present.

The invention is illustrated in the drawing and is described in more detail below using an exemplary embodiment. Show it:

FIG. 2 shows a cylinder housing, shown in cross section, of a multi-cylinder internal combustion engine with a plug-in pump,

In Fig. 1 und 3 ist ein Zylindergehäuse 1 für eine mehrzylindrige Brennkraftmaschine 2 mit in Reihe angeordneten Zylindern 3 sowie mit im Zylindergehäuse 1 vorgesehenen hochstehenden Aufnahmebohrungen 4 für die Aufnahme von magnetventilgesteuerten Steckpumpen 5 gezeigt. Jede einem Zylinder 3 zugeordnete Steckpumpe 5 setzt sich aus einem Pumpenteil mit einem im Pumpengehäuse 6 geführten Pumpenstempel 7 und einem Betätigungsteil mit einem mit dem Pumpenstempel zusammenwirkenden und durch den Nocken 8 einer Nockenwelle 9 angetriebenen federbelasteten Rollenstößel 10 zusammen.1 and 3 show a cylinder housing 1 for a multi-cylinder internal combustion engine 2 with cylinders 3 arranged in series and with upstanding receiving bores 4 provided in the cylinder housing 1 for receiving solenoid-controlled plug-in pumps 5. Each plug-in pump 5 assigned to a cylinder 3 is composed of a pump part with a pump plunger 7 guided in the pump housing 6 and an actuating part with one which interacts with the pump plunger and spring-loaded roller tappet 10 driven by the cam 8 of a camshaft 9 together.

Pumpenteil und Betätigungsteil sind durch eine beide Teile umgebende langgestreckte Hülse 11 baueinheitlich zusammengefaßt (Fig. 2) und stecken in der Aufnahmebohrung 4, die in Bohrungsabschnitte 4a und 4b aufgeteilt ist, welche mit Abstand auseinanderliegen. In den im Zylindergehäuse 1 obenliegenden Bohrungsabschnitt 4a steckt der untere Bereich des Pumpengehäuses 6, während in dem untenliegenden Bohrungsabschnitt 4b die Hülse 11 steckt. In der Hülse 11 ist der Rollenstößel 10 gegen die Kraft einer Rollenstößelfeder 12 längsverschiebbar geführt. Ein hülsenfester Gleitstein 11a und eine schlitzartige Gleitsteinführung 10a in dem Rollenstößel 10 bilden eine Verliersicherung, so daß beim Entfernen der Steckpumpe 5 aus der Aufnahmebohrung 4 ein Herausfallen des Rollenstößels 12 aus der Hülse 11 verhindert wird.The pump part and the actuating part are combined in terms of construction by means of an elongated sleeve 11 surrounding both parts (FIG. 2) and are inserted in the receiving bore 4, which is divided into bore sections 4a and 4b, which are spaced apart. The lower region of the pump housing 6 is inserted into the bore section 4a located in the cylinder housing 1, while the sleeve 11 is inserted in the bore section 4b located below. In the sleeve 11, the roller tappet 10 is guided to be longitudinally displaceable against the force of a roller tappet spring 12. A sleeve-fixed sliding block 11a and a slot-like sliding block guide 10a in the roller plunger 10 form a captive device, so that when the plug-in pump 5 is removed from the receiving bore 4, the roller plunger 12 is prevented from falling out of the sleeve 11.

Der untere Bereich des Pumpengehäuses 6 ist stufig ausgebildet, wobei der durchmessermäßig größere Teil 6a zwei übereinanderliegende Abdichtringe 13, 14 aufweist und in dem obenliegenden Bohrungsabschnitt 4a gelagert ist und wobei der durchmessermäßig kleinere Teil 6b mit dem oberen Teil der Hülse 11 fest verbunden ist. Eine durch die Stufe gebildete Druckschulter 15 am Pumpengehäuse 6 liegt dabei auf der Stirnfläche der Hülse 6 auf.The lower region of the pump housing 6 is of stepped construction, the larger-diameter part 6a having two sealing rings 13, 14 lying one above the other and being mounted in the upper bore section 4a, and the smaller-diameter part 6b being firmly connected to the upper part of the sleeve 11. A pressure shoulder 15 formed by the step on the pump housing 6 lies on the end face of the sleeve 6.

Der aus der Aufnahmebohrung 4 herausragende und freiliegende Pumpengehäuseteil 6 enthält ein Magnetventil 16 zur Steuerung der Strömungswege in den Kraftstoffleitungen.The pump housing part 6, which projects from the receiving bore 4 and is exposed, contains a solenoid valve 16 for controlling the flow paths in the fuel lines.

Die Steckpumpe 5 ist so plaziert, daß deren Längsachse a und die Zylinderachse b einen Winkel α von etwa 10° einschließen.The plug-in pump 5 is placed in such a way that its longitudinal axis a and the cylinder axis b enclose an angle α of approximately 10 °.

Die Längsachse a verläuft quer zur Achse c der Nockenwelle 9, wobei die gedachte Verlängerung der Längsachse a einen Abstand x zur Nockenwellenachse c aufweist, derart, daß die verlängerte Längsachse a der Steckpumpe 5 hinter der Nockenwellenachse c liegt - von dem Zylinder 3 ausgehend in Richtung Nockenwelle 9 betrachtet. Die Drehrichtung der Nockenwelle 9 ist entgegen dem Uhrzeigersinn, das bedeutet, daß die Rolle 17 des Rollenstößels 10 als Nachläufer wirkt und somit eine stabile Ausrichtung in ihrer Lagerung und ihrem Lauf erhält.The longitudinal axis a extends transversely to the axis c of the camshaft 9, the imaginary extension of the longitudinal axis a being at a distance x from the camshaft axis c such that the elongated longitudinal axis a of the plug-in pump 5 is behind the camshaft axis c lies - viewed from the cylinder 3 in the direction of the camshaft 9. The direction of rotation of the camshaft 9 is counterclockwise, which means that the roller 17 of the roller tappet 10 acts as a follower and thus receives a stable alignment in its storage and its running.

Durch die besondere Plazierung bzw. Zuordnung der Steckpumpe 5 zur Nockenwelle 9 können Stößelführungen 18, 19 eines jeden Zylinders 3 enger zusammengeführt werden und demzufolge die benachbarten Zylinder 3 näher beieinander liegen (Fig. 3). Als Vorteile ergeben sich eine Gewichtsersparnis und Reduzierung des Bauraumes.Due to the special placement or assignment of the plug-in pump 5 to the camshaft 9, tappet guides 18, 19 of each cylinder 3 can be brought closer together and, consequently, the adjacent cylinders 3 are closer together (FIG. 3). The advantages are a saving in weight and a reduction in installation space.

Der aus der Aufnahmebohrung 4 herausragende freiliegende Pumpengehäuseteil ist mit einem seitlichen Gehäusevorsprung 20 versehen. Dieser Teil des Pumpengehäuses und der Gehäusevorsprung 20 liegen auf einer Auflagefläche 21 des Zylindergehäuses 1 auf, die im rechten Winkel zur Längsachse a der Steckpumpe 5 verläuft.The exposed pump housing part protruding from the receiving bore 4 is provided with a lateral housing projection 20. This part of the pump housing and the housing projection 20 rest on a bearing surface 21 of the cylinder housing 1, which runs at right angles to the longitudinal axis a of the plug-in pump 5.

Der seitliche Gehäusevorsprung 20 weist eine Kraftstoffleitung 22 mit einem parallel zur Längsachse a der Steckpumpe 5 verlaufenden und stufig ausgebildeten Leitungsabschnitt 23 auf, der koaxial zu einem Zuführkanal 24 im Zylindergehäuse 1 angeordnet ist. Der Zuführkanal 4 zweigt von einem Längskanal 25 ab, der sich im Zylindergehäuse 1 neben den Steckpumpen 5 als durchgehender Kraftstoffvorlauf erstreckt.The lateral housing projection 20 has a fuel line 22 with a stepped line section 23 which runs parallel to the longitudinal axis a of the plug-in pump 5 and is arranged coaxially with a feed channel 24 in the cylinder housing 1. The feed channel 4 branches off from a longitudinal channel 25 which extends in the cylinder housing 1 next to the plug-in pumps 5 as a continuous fuel feed.

In den Leitungsabschnitt 23 ist eine Hülse 26 bis zu einer durch die Stufe gebildeten Druckschulter 27 eingeschoben und dort fixiert. Die Hülse 26 steckt mit ihrem aus dem Leitungsabschnitt 22 herausragenden Teil in dem Zuführkanal 24 des Zylindergehäuses 1 und bildet eine Lagesicherung für die Steckpumpe 5 in der Aufnahmebohrung 4. Die Steckpumpe 5 ist am Zylindergehäuse 1 durch Befestigungsschrauben 28 befestigt.A sleeve 26 is inserted into the line section 23 up to a pressure shoulder 27 formed by the step and fixed there. The sleeve 26, with its part protruding from the line section 22, is inserted in the feed channel 24 of the cylinder housing 1 and forms a positional securing for the plug-in pump 5 in the receiving bore 4. The plug-in pump 5 is fastened to the cylinder housing 1 by fastening screws 28.

Die der Auflagefläche 21 am Zylindergehäuse 1 gegenüberliegende Anlagefläche 29 am Gehäusevorsprung 20 ist mit einer die Hülse 26 umgebenden Ausnehmung 30 versehen, in der ein Abdichtring 31 liegt, der unter Vorspannung verliersicher auf die Hülse 26 geschoben ist. Die auf diese besondere Weise die Leitungsverbindung zwischen dem Zylindergehäuse 1 und der Steckpumpe herstellende Hülse 26 schützt den Abdichtring 31 gegen den anliegenden sehr hohen Systemdruck.The contact surface 29 on the housing projection 20 opposite the bearing surface 21 on the cylinder housing 1 is provided with a recess 30 surrounding the sleeve 26, in which lies a sealing ring 31 which is pushed onto the sleeve 26 in a captive manner under pretension. The sleeve 26 producing the line connection between the cylinder housing 1 and the plug-in pump in this special way protects the sealing ring 31 against the very high system pressure present.
