Engine block (11) with a pump chamber (12) in which is disposed a pump with a pump neck (8) rotatably about a pump chamber axis (22), wherein the pump neck (8) is arranged eccentrically relative to the pump chamber axis (22) and over the pump neck (8) is provided a cover (2) with a cover opening (26) for the pump neck (8), characterised in that in the cover opening (26) is disposed a base plate (3) with a neck opening (17) for the pump neck (8), which is rotatable in the same eccentric position relative to the pump chamber axis (22) as the pump neck (8), about the latter axis.

Description

Die Erfindung betrifft einen Motorblock mit einem Pumpenraum in dem eine Pumpe mit einem Pumpenhals um eine Pumpenraumachse drehbar angeordnet ist, wobei der Pumpenhals gegenüber der Pumpenraumachse exzentrisch angeordnet ist und über dem Pumpenhals eine Haube mit einer Haubenöffnung für den Pumpenhals vorgesehen ist.The invention relates to an engine block with a pump chamber in which a pump with a pump neck is arranged rotatably about a pump chamber axis, the pump neck being arranged eccentrically with respect to the pump chamber axis and a hood with a hood opening being provided for the pump neck.

Wird der Pumpenhals der Pumpe exzentrisch gegenüber der Pumpenraumachse gedreht, so hat er in der Haubenöffnung stets Raum, noch unter die Haube zu ragen und von derselben abgedeckt zu werden. Dies ist insbesondere dann von Vorteil, wenn in dem Pumpenhals das Abtriebsrad, z. B. für einen antreibenden Zahnriemen gelagert ist. Dieser Zahnriemen läßt sich dadurch spannen, daß der Pumpenhals mit dem Abtriebsrad exzentrisch gegenüber der Pumpenraumachse verdrehbar ist und dabei seine Lage gegenüber dem Zahnriemen zur Spannung desselben verändern kann. Auch in diesem Falle soll das Abtriebsrad mit dem Zahnriemen unter der Haube liegen. Die Haube hat dabei allgemein den Zweck, den Pumpenhals gegebenenfalls mit dem Abtriebsrad und dem Zahnriemen abzudecken, so daß versehentlich nicht in die genannten Teile eingegriffen werden kann oder auch Schmutz, wie z. B. Staub, Steine oder ÖI zu den genannten Teilen bzw. dem Pumpenhals vordringen können und damit den Betrieb der genannten Teile und auch der Pumpe selbst beeinträchtigen können. Schließlich dient die Haube auch der Schallabschirmung der Pumpe bzw. der auf ihr bzw. ihrem Hals angeordneten Teile.If the pump neck of the pump is rotated eccentrically with respect to the pump chamber axis, it always has room in the hood opening to protrude under the hood and to be covered by it. This is particularly advantageous if the driven gear, e.g. B. is mounted for a driving toothed belt. This toothed belt can be tensioned in that the pump neck with the driven wheel can be rotated eccentrically with respect to the pump chamber axis and can change its position in relation to the toothed belt to tension the same. In this case too, the driven gear with the toothed belt should be under the hood. The hood has the general purpose of possibly covering the pump neck with the driven gear and the toothed belt, so that it is inadvertently impossible to intervene in the parts mentioned or dirt, such as. B. dust, stones or oil can penetrate to the parts mentioned or the pump neck and thus can impair the operation of the parts mentioned and also the pump itself. Finally, the hood also serves to soundproof the pump or the parts arranged on it or on its neck.

Da der Pumpenhals gegenüber der Pumpenraumachse exzentrisch angeordnet ist und in der Haubenöffnung frei drehbar ist, wird die Haubenöffnung stets größer sein müssen als der Pumpenhals selbst, so daß zwischen dem Pumpenhals und der Haubenöffnung stets ein entsprechend großer freier Raum verbleibt.Since the pump neck is arranged eccentrically with respect to the pump chamber axis and can be freely rotated in the hood opening, the hood opening will always have to be larger than the pump neck itself, so that there is always a correspondingly large free space between the pump neck and the hood opening.

Der Erfindung liegt die Aufgabe zugrunde, den freien Raum zwischen dem Pumpenhals und der Haubenöffnung ebenfalls zu schließen, so daß auch hier keine Beeinträchtigungen mehr eindringen können, also insbesondere kein Staub, Steine oder Öl, und daß auch hier eine Schallabschirmung gegeben ist, während gleichwohl die exzentrische Verdrehbarkeit des Pumpenhalses in der Haubenöffnung möglich sein soll.The invention has for its object to also close the free space between the pump neck and the hood opening, so that no further impairments can penetrate here, in particular no dust, stones or oil, and that here too there is sound shielding, while nevertheless the eccentric rotatability of the pump neck in the hood opening should be possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in der Haubenöffnung ein Grundblech mit einer Halsöffnung für den Pumpenhals in gleicher exzentrischer Lage gegenüber der Pumpenraumachse wie der Pumpenhals um dieselbe drehbar angeordnet ist. Die Halsöffnung läßt sich nun so eng wählen, wie die Außenkontur des Pumpenhalses. Da sie in gleicher exzentrischer Lage gegenüber der Pumpenraumachse liegt, wie der Pumpenhals, kann der Pumpenhals wie vordem exzentrisch um die Pumpenraumachse gedreht werden, wobei ihm das Grundblech mit der Halsöffnung in der Haubenöffnung folgen kann.This object is achieved in that a base plate with a neck opening for the pump neck in the same eccentric position relative to the pump chamber axis as the pump neck is rotatably arranged about the same in the hood opening. The neck opening can now be selected as closely as the outer contour of the pump neck. Since it is in the same eccentric position with respect to the pump chamber axis as the pump neck, the pump neck can be rotated eccentrically around the pump chamber axis as before, whereby the base plate with the neck opening in the hood opening can follow it.

Bevorzugt ist, daß die Haubenöffnung und das Grundblech rund sind und konzentrisch zu der Pumpenraumachse angeordnet sind, wobei das Grundblech in der Haubenöffnung zwischen einer Unterlippe und einer Oberlippe liegt. In diesem Fall wird das Grundblech zwischen der Unter-und der Oberlippe in einer Rille zwischen denselben rund geführt, wobei die Rundführung konzentrisch zu der Pumpenraumachse ist, also der Drehbewegung um dieselbe entspricht. Da der Pumpenhals ebenfalls um die Pumpenraumachse gedreht wird, kann die Halsöffnung in dem Grundblech der Drehbewegung des Pumpenhalses exakt folgen.It is preferred that the hood opening and the base plate are round and are arranged concentrically to the pump chamber axis, the base plate lying in the hood opening between a lower lip and an upper lip. In this case, the base plate between the lower and the upper lip is guided round in a groove between them, the round guide being concentric to the pump chamber axis, that is to say corresponding to the rotational movement about the same. Since the pump neck is also rotated about the pump chamber axis, the neck opening in the base plate can exactly follow the rotary movement of the pump neck.

Um das Grundblech zwischen die Unter- und die Oberlippe bringen zu können, ist bevorzugt, daß im Außenrand des Grundbleches ein Ausschnitt mit einer Stufe und in der Unterlippe eine Aussparung vorgesehen sind. Die Stufe kann dann zunächst in die Aussparung in der Unterlippe eingeführt werden, wobei ansonsten zwischen dem Grundblech und der Unterlippe vermöge des Ausschnittes in dem Grundblech Raum gegeben wird. Sodann läßt sich das Grundblech mit der Stufe zwischen die Unter- und die Oberlippe eindrehen, bis der gesamte umlaufende Rand des Grundbleches zwischen der Unter- und der Oberlippe untergebracht ist.In order to be able to bring the base plate between the lower and the upper lip, it is preferred that a cutout with a step is provided in the outer edge of the base plate and a recess is provided in the lower lip. The step can then first be introduced into the recess in the lower lip, otherwise space is given between the base plate and the lower lip due to the cutout in the base plate. Then the base plate can be screwed in with the step between the lower and the upper lip until the entire circumferential edge of the base plate is accommodated between the lower and the upper lip.

The invention will be further explained on the basis of the exemplary embodiment shown in the figures. Show it :
  • Figure 1 shows the cross section through an engine block with a pump and the hood completed according to the invention.
  • 2 shows the top view of the base plate according to the invention;
  • 3 shows the cross section through the base plate according to the section line 111-111 in Fig. 2.

  • 5 shows a cross section through the hood along the section line VV in FIG. 4.

In Fig. 1 ist im Querschnitt ein Motorblock 11 mit einer Pumpe und einer über ihrem Pumpenhals 8 angeordneten Haube 2 dargestellt. Der gewählte Querschnitt verläuft entlang der Pumpenraumachse 22 und der zu ihr parallel jedoch um den Exzentrizitätsabstand 24 beanstandet verlaufenden Wellenachse bzw. HaIsöffnungsachse 21. In dem Motorblock 11 ist der Pumpenraum 12 belassen. Der Pumpenraum 12 besitzt die runde Pumpenwand 23, an der die runde Pumpengehäuseplatte 10 anliegt. Gegenüber dem Motorblock 11 ist die Pumpengehäuseplatte 10 mit der Dichtung 9 abgedichtet. Die Pumpengehäuseplatte 10 läßt sich somit an der Pumpenwand 23 in dem Pumpenraum 12 um die Pumpenraumachse 22 drehen. Nach außen, in der Fig. nach oben, ragt von der Pumpengehäuseplatte 10 der Pumpenhals 8. Im dem Pumpenhals 8 ist eine Welle 7 gelagert, die in dem Pumpenraum 12 den Rotor 6 der Pumpe trägt. Auf dem Pumpenhals 8, also außerhalb desselben, trägt die Welle 7 das Abtriebsrad 5, auf dem der Riemen 4, insbesondere ein Zahnriemen, abläuft. Darüber ist die Haube 2 mit dem Deckel 1 angeordnet. Zwischen dem Deckel 1 und der Haube 2 ist ein Moosgummi 19 vorgesehen ; es sei darauf hingewiesen, daß der Deckel 1 die Haube 2 lediglich vervollständigt, daß also der Deckel 1 an sich Bestandteil der Haube 2 ist bzw. die Haube 2 den Deckel 1 begrifflich umfaßt. Somit werden der Pumpenhals 8, das Abtriebsrad 5 und der Riemen 4 von der Haube 2 mit dem Deckel 1 in an sich bekannter Weise abgedeckt. Zwischen dem Pumpenhals 8 und der Haube 2 ist die an sich bekannte Haubenöffnung 26 gegeben. In dieser Haubenöffnung 26 liegt nun erfindungsgemäß das Grundblech 3, das eine Halsöffnung 17 für den Pumpenhals 8 besitzt. Die Halsöffnung 17 schließt mit dem Pumpenhals 8 bündig ab, ebenso schließt das Grundblech 3 auf seinem Umfang mit der Rinne zwischen der Unterlippe 15 und der Oberlippe 16 am Rand der Haubenöffnung 26 bündig ab.1 shows in cross section an engine block 11 with a pump and a hood 2 arranged above its pump neck 8. The selected cross section runs along the pump chamber axis 22 and the shaft axis or shaft opening axis 21, which runs parallel to it but is objected to by the eccentricity distance 24. The pump chamber 12 is left in the motor block 11. The pump chamber 12 has the round pump wall 23 against which the round pump housing plate 10 bears. The pump housing plate 10 is sealed with the seal 9 with respect to the motor block 11. The pump housing plate 10 can thus be rotated on the pump wall 23 in the pump chamber 12 about the pump chamber axis 22. The pump neck 8 protrudes outwards, in the figure upwards, from the pump housing plate 10. A shaft 7 is mounted in the pump neck 8 and the rotor 6 in the pump chamber 12 the pump carries. On the pump neck 8, ie outside the same, the shaft 7 carries the driven wheel 5, on which the belt 4, in particular a toothed belt, runs. In addition, the hood 2 with the lid 1 is arranged. A foam rubber 19 is provided between the cover 1 and the hood 2; it should be noted that the cover 1 only completes the hood 2, that is to say that the cover 1 is in itself part of the hood 2 or the hood 2 conceptually encompasses the cover 1. The pump neck 8, the driven wheel 5 and the belt 4 are thus covered by the hood 2 with the cover 1 in a manner known per se. The hood opening 26 known per se is provided between the pump neck 8 and the hood 2. According to the invention, the base plate 3, which has a neck opening 17 for the pump neck 8, now lies in this hood opening 26. The neck opening 17 is flush with the pump neck 8, and the base plate 3 is also flush on its circumference with the groove between the lower lip 15 and the upper lip 16 at the edge of the hood opening 26.

In Fig. 2 ist die Form des Grundbleches in Draufsicht deutlich zu erkennen. Exzentrisch in dem an sich konzentrisch zu der Pumpenraumachse 22 liegenden und runden Rundblech 3 liegt die Halsöffnung 17 für den Pumpenhals. Die Halsöffnung 17 besitzt einen Kragen 20, um die Anlagefläche zwischen dem Grundblech 3 und dem Pumpenhals 8 zu vergrößern. Auf dem Umfang des Grundbleches 3 ist ein Ausschnitt 25 vorgesehen, der von einer Stufe 13 beendet wird.In Fig. 2 the shape of the base plate can be clearly seen in plan view. The neck opening 17 for the pump neck lies eccentrically in the round sheet metal 3, which is concentric with the pump chamber axis 22. The neck opening 17 has a collar 20 in order to enlarge the contact surface between the base plate 3 and the pump neck 8. A cutout 25 is provided on the circumference of the base plate 3 and is terminated by a step 13.

In Fig. 3 ist das Grundblech aus Fig. 2 entlang der Schnittlinie 111-111 im Querschnitt dargestellt. Die Versteifungssicke 18 dient zur Versteifung des Grundbleches 3 in an sich bekannter Weise.In FIG. 3 the base plate from FIG. 2 is shown in cross section along the section line 111-111. The stiffening bead 18 serves to stiffen the base plate 3 in a manner known per se.

In Fig. 4 ist die Haube 2 ohne den Deckel 1 in Draufsicht aus der Blickrichtung B in Fig. 1 dargestellt. Die Haube 2 ist nicht vollkommen rund, sondern besitzt zwei Riemendurchlässe 27. An diesen Stellen kann der Riemen in die Haube zu dem Antriebsrad, das nicht zu erkennen ist, eintreten. Dies ist an sich bekannt. In der allerdings von dem Deckel 1 und der Oberlippe 16 verdeckten Unterlippe 15 ist die Aussparung 14 angedeutet. Die Aussparung 14 bedeutet einen Abschnitt in der Unterlippe 15, der bis zum Boden der Rille zwischen der Unterlippe 15 und der Oberlippe 16 reicht.4 shows the hood 2 without the cover 1 in a top view from the viewing direction B in FIG. 1. The hood 2 is not completely round, but has two belt passages 27. At these points, the belt can enter the hood to the drive wheel, which cannot be seen. This is known per se. The recess 14 is indicated in the lower lip 15, which is however covered by the cover 1 and the upper lip 16. The recess 14 means a section in the lower lip 15 which extends to the bottom of the groove between the lower lip 15 and the upper lip 16.

In dieser Aussparung 14 kann das Grundblech 3 mit der Stufe 13 eingeschoben werden und schließlich vollkommen zwischen die Unterlippe 15 und die Oberlippe 16 hineingedreht und damit hineingeschoben werden. Im Ergebnis liegt dann das Grundblech 3 mit seinem Außenrand vollständig zwischen der Unterlippe 15 und der Oberlippe 16. Zwischen den Lippen kann dann das Grundblech gedreht werden, wenn auch gegebenenfalls nur unter Überwindung einer Klemmreibung.In this recess 14, the base plate 3 can be inserted with the step 13 and finally screwed completely between the lower lip 15 and the upper lip 16 and thus inserted. As a result, the base plate 3 then lies with its outer edge completely between the lower lip 15 and the upper lip 16. The base plate can then be rotated between the lips, even if only by overcoming a clamping friction.

Somit ist ein dichter Abschluß zwischen der Haubenöffnung und dem Pumpenhals gewährleistet, obgleich der Pumpenhals in an sich bekannter Weise exzentrisch in der Haubenöffnung bewegt werden kann.This ensures a tight seal between the hood opening and the pump neck, although the pump neck can be moved eccentrically in the hood opening in a manner known per se.

In Fig. 5 ist schließlich der Querschnitt entlang der Schnittlinie V-V aus Fig. 4 gezeigt. Deutlich ist die Rinne zwischen der Unterlippe 15 und der Oberlippe 16 in der Haubenöffnung 26 zu erkennen.5 shows the cross section along the section line V-V from FIG. 4. The channel between the lower lip 15 and the upper lip 16 in the hood opening 26 can be clearly seen.
