Description

Die Erfindung betrifft ein Motorpumpenaggregat, insbesondere ein tragbares Motorpumpenaggregat, gemäß Oberbegriff des Patentanspruches 1.The invention relates to a motor pump unit, in particular a portable motor pump unit, according to the preamble of claim 1.

Bei solchen Motorpumpenaggregaten hat sich eine Standardbauweise durchgesetzt, bei der das Ölgehäuse ungeschützt, sozusagen nackt, in der jeweiligen Betriebsposition frei liegt. Zum Teil ist dies damit begründet, dass eine direkte Wärmeabstrahlung in die Umgebung den Kühleffekt des Kühlgebläses unterstützen soll. Beispiele solcher Motorpumpenaggregate sind zu finden in EP 0 198 250 A2 , DE 38 39 689 A1 , CH 596 697 A5 , US 6 589 029 B1 , EP 1 731 762 A1 , EP 0 284 746 A1 .In such motor pump units, a standard construction has prevailed, in which the oil housing is unprotected, so to speak, naked, in the respective operating position. In part, this is due to the fact that a direct heat radiation into the environment should support the cooling effect of the cooling fan. Examples of such motor pump units can be found in EP 0 198 250 A2 . DE 38 39 689 A1 . CH 596 697 A5 . US Pat. No. 6,589,029 B1 . EP 1 731 762 A1 . EP 0 284 746 A1 ,

Wird ein Motorpumpenaggregat mit einem hydraulisch betriebenen Werkzeug im Feld eingesetzt, beispielsweise mit einem Drehmomentschrauber, einem Kabelschuh-Clincher, einer Blech- oder Unfallschere, und dgl., dann ist der relativ schlanke und wegen des endseitigen Kühlgebläses lange Gegenstand nicht nur unhandlich zu transportieren und aufzustellen, sondern zeigt sich, dass mit der an den Seitenwänden relativ unkontrollierten Kühlluftströmung des endseitigen Kühlgebläses die Effizienz der Kühlung unbefriedigend ist. Speziell bei längerem oder Dauerbetrieb führt dies zu Nachteilen. Im Betrieb des Motorpumpenaggregats entsteht nämlich durch den Elektromotor und auch das sich beim Arbeiten erwärmende Hydrauliköl relativ viel Wärme, die sich im Motorpumpenaggregat konzentriert und effizient abgeführt werden muss, um Dichtungen und das Öl selbst wie auch den Elektromotor zu schützen. Das meist verrippte Ölgehäuse neigt unter Witterungseinflüssen zu relativ rascher Verschmutzung, wodurch die Kühlwirkung noch weiter vermindert wird. Außerdem ist das Erscheinungsbild extrem stark durch rein technische Merkmale geprägt und resultieren aus in der Praxis unvermeidlichen Kollisionen beim Transport und im Betrieb Beschädigungen gegebenenfalls auch an den Kühlrippen.If a motor pump unit used with a hydraulically operated tool in the field, for example with a torque wrench, a cable shoe clincher, a sheet metal or accident scissors, and the like., Then the relatively slim and because of the end cooling fan long object not only unwieldy to transport and but show that with the relatively uncontrolled on the side walls of cooling air flow of the end-side cooling fan, the cooling efficiency is unsatisfactory. Especially in prolonged or continuous operation, this leads to disadvantages. During operation of the motor pump unit, a relatively large amount of heat is generated by the electric motor and the hydraulic oil that heats up when working, which must be concentrated in the motor pump unit and efficiently dissipated in order to protect seals and the oil itself as well as the electric motor. The mostly ribbed oil housing tends to weather under relatively rapid pollution, whereby the cooling effect is further reduced. In addition, the appearance is extremely strongly characterized by purely technical features and result from inevitable collisions in practice during transport and operation damage possibly also on the cooling fins.

Der Erfindung liegt die Aufgabe zugrunde, ein Motorpumpenaggregat der eingangs genannten Art im Hinblick auf den erzielbaren Kühleffekt, die Handhabung speziell im Feld, das äußere Erscheinungsbild und einen Schutz gegen Umwelteinflüsse zu verbessern.The invention has for its object to improve a motor pump unit of the type mentioned in terms of the achievable cooling effect, handling specifically in the field, the external appearance and protection against environmental influences.

Die gestellte Aufgabe wird mit den Merkmalen des Patentanspruches 1 gelöst.The stated object is achieved with the features of claim 1.

Das an wenigstens einer Außenseite angeordnete, wenigstens eine Kühlgebläse kühlt überraschend eine besser als wenigstens ein endseitiges Kühlgebläse, auch weil das Außengehäuse eine gezielte Kühlluftführung unterstützt. Insgesamt resultiert bei gleichem Energieeinsatz für das Kühlgebläse eine höhere und gleichmäßigere Kühlleistung. Das Außengehäuse ist ein Multifunktions-Außengehäuse, da es nicht nur der Kühlluftführung dient, sondern auch das Kühlgebläse nach außen abdeckt, Eingriffe von außen in das Kühlgebläse verwehrt, gegen direkte Einwirkung von Schmutz und Witterung auf das Ölgehäuse und gegebenenfalls sensible Ausstattungskomponenten schützt, beim Einsatz im Feld Kollisionen abpuffert und vom Ölgehäuse fernhält, und schließlich sogar ein gefälliges weil kompaktes Erscheinungsbild des Motorpumpenaggregats vermittelt. Die Anordnung des Kühlgebläses an der Seitenwand verringert ferner die Bauhöhe des Motorpumpenaggregats, das in der Einkleidung des Außengehäuses ein bequem handhabbares Format hat. Darüber hinaus lässt sich das Außengehäuse für weitere Hilfsfunktionen gut nutzen und verbessert es gegebenenfalls die Standfestigkeit des Motorpumpenaggregats.The arranged on at least one outer side, at least one cooling fan cools surprisingly better than at least one end-side cooling fan, also because the outer casing supports a targeted cooling air flow. Overall results for the same energy use for the cooling fan has a higher and more even cooling capacity. The outdoor enclosure is a multifunctional outdoor enclosure, as it not only provides cooling air flow, but also shields the cooling fan from the outside, prevents external interference with the cooling fan, protects against direct impact of dirt and weather on the oil housing, and protects sensitive equipment components when in use In the field collisions buffers and keeps away from the oil housing, and finally even a pleasing because compact appearance of the motor pump unit conveys. The arrangement of the cooling fan on the side wall further reduces the overall height of the motor pump assembly, which has a convenient manageable format in the lining of the outer housing. In addition, the outer housing can be well used for other auxiliary functions and it improves if necessary, the stability of the motor pump unit.

In einer zweckmäßigen Ausführungsform ist das Kühlgebläse mit einem elektrischen Antriebsmotor hinter Einlässen des Außengehäuses an der Seitenwand des Ölgehäuses montiert. Auf diese Weise wird kühle Außenluft angesaugt und vom Kühlgebläse sowie dem Außengehäuse gezielt an den Seitenwänden des Ölgehäuses verteilt, d.h., in einem Bereich, in welchem innen im Ölgehäuse der Wärme produzierende Elektromotor und der größte Teil des Wärme enthaltenden Ölreservoirs angeordnet sind. Die Einlässe können gegebenenfalls mit einem Luftfilter kombiniert werden, um das Verschmutzen und Benässen der Seitenwände des Ölgehäuses, speziell von Kühlrippen, zu minimieren.In an expedient embodiment, the cooling fan is mounted with an electric drive motor behind inlets of the outer housing on the side wall of the oil housing. In this way, cool outside air is sucked and distributed by the cooling fan and the outer casing targeted to the side walls of the oil housing, that is, in a region in which the inside of the oil housing, the heat-producing electric motor and most of the heat-containing oil reservoir are arranged. If necessary, the inlets can be combined with an air filter to minimize fouling and wetting of the side walls of the oil housing, especially cooling fins.

Bei einer zweckmäßigen Ausführungsform weist das Kühlgebläse eine Außenverkleidung auf (Kapselbauweise), und besitzt das Außengehäuse als Umrandung der Kühlluft-Einlässe einen innenseitigen, die Außenverkleidung des Kühlgebläses umgreifenden Rahmen. Auf diese Weise wird u.a. eine verbesserte Luftführung in das Kühlgebläse erzwungen.In an advantageous embodiment, the cooling fan has an outer lining (capsule construction), and has the outer housing as a border of the cooling air inlets an inside, the outer lining of the cooling fan enclosing frame. In this way, u.a. forced an improved air flow into the cooling fan.

Um auch hohem Kühlbedarf gerecht werden zu können, ist es zweckmäßig, wenn sogar an zwei voneinander abgewandten Seitenwänden des Ölgehäuses jeweils mindestens ein Kühlgebläse im Inneren des Außengehäuses angeordnet ist. Auf diese Weise lassen sich alle Seitenwände des Ölgehäuses intensiv und effizient kühlen. Gegebenenfalls wird an jeder Seitenwand ein Kühlgebläse eingesetzt.In order to meet even high cooling requirements, it is expedient if in each case at least one cooling fan is arranged in the interior of the outer housing even on two side walls of the oil housing facing away from each other. In this way, all side walls of the oil housing can be cooled intensively and efficiently. Optionally, a cooling fan is used on each side wall.

In einer günstigen Ausführungsform weist das einen annähernd viereckigen, gegebenenfalls etwas gerundeten Außenumriss aufweisende Ölgehäuse außenseitige, längs verlaufende Kühlrippen auf, um der Kühlluft eine möglichst große Oberfläche anzubieten. Bevorzugt wird das jeweilige Kühlgebläse mit einem im Querschnitt C-förmigen Stützrahmen im Abstand von den Kühlrippen positioniert und mit hinter Kühlrippen zweier angrenzender Seitenwände eingehängten Haken festgelegt. Diese einfache, aber sichere Befestigungsweise ermöglicht es auch, die optimale Position des Kühlgebläses in Längsrichtung des Ölgehäuses nach Bedarf zu wählen.In a favorable embodiment, the approximately square, optionally slightly rounded outer contour having oil housing on the outside, longitudinally extending cooling fins to offer the cooling air as large a surface as possible. Preferably, the respective cooling fan is positioned with a cross-sectionally C-shaped support frame at a distance from the cooling fins and hinged with rear fins of two adjacent side walls Hook set. This simple but secure way of mounting also allows you to choose the optimum position of the cooling fan in the longitudinal direction of the oil housing as needed.

In einer günstigen Ausführungsform weist das Außengehäuse zwei Gehäusehälften auf, die weitgehend spiegelbildlich und dreidimensional ausgebildet sein können, und deren jede über drei aneinander angrenzende Seitenwände und die Enden des Ölgehäuses greifende Gehäusewände besitzt. Auf diese Weise ist das Ölgehäuse weitgehend vom Außengehäuse umschlossen und äußeren Einflüssen entzogen.In a favorable embodiment, the outer housing on two housing halves, which may be formed largely mirror-inverted and three-dimensional, and each of which has three adjacent side walls and the ends of the oil housing cross-housing walls. In this way, the oil housing is largely enclosed by the outer housing and removed external influences.

Dabei kann es zweckmäßig sein, wenn jede Gehäusehälfte einstückig ausgebildet ist, obwohl nicht ausgeschlossen sein soll, jede Gehäusehälfte aus mehreren Einzelteilen zu fügen.It may be expedient if each housing half is formed in one piece, although it should not be excluded to add each housing half of several items.

Um die empfindlichen Kühlrippen nicht zu beschädigen, ist es zweckmäßig, wenn das Außengehäuse an wenigstens einem Ende oder sogar an beiden Enden des Ölgehäuses befestigt ist, vorzugsweise an einem aufstellseitigen Ende mit Schraubstandfüßen und am gegenüberliegenden Ende mit Befestigungsschrauben. Diese stabile Befestigungsweise des Außengehäuses erhöht die Schutzwirkung für das Ölgehäuse.In order not to damage the sensitive cooling fins, it is expedient if the outer housing is attached to at least one end or even at both ends of the oil housing, preferably at a Aufstellseitigen end with Schraubstandfüßen and at the opposite end with mounting screws. This stable attachment of the outer housing increases the protective effect of the oil housing.

Zweckmäßig ist auf dem Außengehäuse mit das Außengehäuse an einem oben liegenden Ende des Ölgehäuses festlegenden Befestigungsschrauben wenigstens eine Konsole befestigt, die wenigstens eine Hängeöse und/oder einen Traggriff aufweist. Dies verbessert die Handhabung des Motorpumpenaggregats beim Einsatz im Feld, beispielsweise um das Motorpumpenaggregat mit einem Hebezeug auf die Gondel einer Windturbine zu transportieren, oder bequem über längere Strecken zu tragen, wobei die kompakte, nahezu würfelförmige Bauweise des mit dem seitlichen Kühlgebläse eingehausten Motorpumpenaggregats im Feld erhöht. Das Außengehäuse könnte sogar Bodenlaufrollen aufweisen.It is expedient for at least one console, which has at least one suspension eye and / or a carrying handle, to be attached to the outer housing with the outer housing at an upper end of the oil housing. This improves the handling of the motor pump unit when used in the field, for example, to transport the motor pump unit with a hoist on the nacelle of a wind turbine, or comfortable to wear over longer distances, the compact, almost cube-shaped design of the housed with the lateral cooling fan motor pump unit in the field elevated. The outer housing could even have floor running wheels.

Ferner kann das Außengehäuse eine weitere Funktion übernehmen, indem es außenliegende Kabelhalter aufweist, beispielsweise für ein elektrisches Anschlusskabel und/oder ein mit einer Fernbedienung verbundenes Steuerungskabel. Das bzw. die Kabel können so beim Transport oder Nichtgebrauch bequem verstaut werden.Furthermore, the outer housing can take on a further function by having external cable holder, for example for an electrical connection cable and / or connected to a remote control cable. The cable (s) can be conveniently stowed during transport or when not in use.

Das Außengehäuse ist zweckmäßig aus Kunststoff und/oder Metall, z.B. Blech hergestellt. Die Bauweise aus Kunststoff kann beispielsweise Spritzguss-Formteile nutzen. Bei Blech oder Metall bietet sich eine einfache Kant- und/oder Schraub- und/oder Schweißkonstruktion an. Das Außengehäuse, speziell aus Kunststoff, ist sehr leicht und aufgrund der dreidimensionalen Außengehäusehälften dennoch stabil. Auch Mischbauweisen des Außengehäuses sind möglich. Das Außengehäuse weist mindestens eine Ausblasöffnung für erwärmte Kühlluft auf. Zweckmäßig ist eine Ausblasöffnung so ausgebildet und angeordnet, dass sie den Verteilerblock und einen Klemmenkasten mit einer daran angeordneten Aggregatsteuerung von außen her umgreift, d.h., dann der Anschlussblock wie auch die Aggregatsteuerung außen zugänglich sind und von der ausgeblasenen Kühlluftströmung sowie der kühleren Außenumgebung effizient kühlgehalten werden. Denn Magnete am Verteilerblock und die elektronische Steuerung produzieren für sie schädliche Wärme.The outer housing is suitably made of plastic and / or metal, eg sheet metal. The construction of plastic, for example, use injection molded parts. For sheet metal or metal, a simple Kant and / or screw and / or welded construction offers. The outer casing, especially made of plastic, is very light and yet stable due to the three-dimensional outer casing halves. Mixed construction of the outer housing are possible. The outer housing has at least one blow-out opening for heated cooling air. Appropriately, an exhaust opening is designed and arranged so that it surrounds the manifold block and a terminal box with an attached unit control from the outside, ie, then the terminal block as well as the unit control are externally accessible and efficiently kept cool by the blown cooling air flow and the cooler outdoor environment , Magnets on the distributor block and the electronic control system produce harmful heat for them.

Ferner kann es zweckmäßig sein, im Außengehäuse auch an der dem Anschlussblock abgewandten Seitenwand des Ölgehäuses eine in Längsrichtung des Ölgehäuses verlaufende, schlitzförmige Ausblasöffnung vorzusehen, die sich, vorzugsweise, über in etwa die gesamte Länge des Ölgehäuses erstrecken kann, und auch einen relativ hohen Kühlluftdurchsatz, der selbstreinigend wirkt, ausströmen lässt. Die Ausblasöffnung oder die Ausblasöffnungen können im Übrigen so dimensioniert werden, dass sich im Inneren des Außengehäuses ein für die Kühlwirkung optimaler Staudruck ausbildet.Furthermore, it may be expedient to provide in the outer housing also on the side wall of the oil housing facing away from the terminal block, a slot-shaped exhaust opening extending, preferably, over approximately the entire length of the oil housing, and also a relatively high cooling air flow rate that acts self-cleaning, lets it flow out. Incidentally, the blow-out opening or the blow-out openings can be dimensioned such that a dynamic pressure which is optimal for the cooling effect is formed in the interior of the outer housing.

Um schließlich die Schutzwirkung für das Ölgehäuse weiter zu erhöhen, können zwischen dem Außengehäuse und dem Ölgehäuse elastische Kissen vorgesehen werden, die nicht nur bei einem dünnwandigen Außengehäuse Kontakt zwischen dem Außengehäuse und dem Ölgehäuse verhindern, sondern auch die dünnen Wände des Außengehäuses stabilisieren.Finally, to further increase the protective effect on the oil casing, elastic pads may be provided between the outer casing and the oil casing to prevent contact between the outer casing and the oil casing not only in a thin-walled outer casing, but also to stabilize the thin walls of the outer casing.

Fig. 1 zeigt ein Motorpumpenaggregat M, das in ein Außengehäuse 2 eingekleidet ist. Das Außengehäuse 2 besteht beispielsweise aus Kunststoff und/oder Blech und umschließt das Motorpumpenaggregat M weitestgehend zumindest bis auf wenigstens eine Ausblasöffnung A1 (oder zwei Ausblasöffnungen A1, A2, siehe Fig. 2). Das Motorpumpenaggregat M ist z.B. tragbares Zubehör eines hydraulisch betreibbaren Werkzeugs und ist z.B. etwa 30 kg schwer. Fig. 1 shows a motor pump unit M, which is clad in an outer housing 2. The outer housing 2 consists for example of plastic and / or sheet metal and surrounds the motor pump unit M largely at least up to at least one exhaust opening A1 (or two exhaust openings A1, A2, see Fig. 2 ). The motor pump unit M is, for example, portable accessories of a hydraulically operated tool and is for example about 30 kg heavy.

Auf dem Außengehäuse 2 ist an der Oberseite des Motorpumpenaggregats M eine Konsole 1 mit Befestigungsschrauben 33 festgelegt, die auch für die Befestigung des Außengehäuses an einem oberen Ende 21 (Fig. 2) eines Ölgehäuses 18 sorgen. Die Konsole 1 trägt mindestens einen Handgriff 3 und/oder mindestens eine Hängeöse 4 zum Transport des Motorpumpenaggregats M beim Einsatz oder zum Einsatz im Feld. An einer Seite des Außengehäuses 2 sind Kabelhalter 5 befestigt, an denen ein Steuerungskabel 7 einer Fernsteuerung 8 beispielsweise während des Transportes verstaubar ist. An der gegenüberliegenden Außenseite des Außengehäuses 2 können weitere Kabelhalter 8, beispielsweise für ein Netzkabel 9, angebracht sein.On the outer housing 2, a bracket 1 is fixed with fastening screws 33 at the top of the motor pump unit M, which also for the attachment of the outer housing at an upper end 21 (FIGS. Fig. 2 ) of an oil housing 18. The console 1 carries at least a handle 3 and / or at least one suspension eye 4 for transporting the motor pump unit M when used or for use in the field. On one side of the outer housing 2 cable holder 5 are attached to which a control cable 7 of a remote control 8, for example, during transport is stowed. On the opposite outer side of the outer housing 2 more cable holder 8, for example, for a power cable 9, be attached.

Vom innenliegenden Ölgehäuse 18 ist in Fig. 1 ein daran montierter Verteilerblock 10 mit nicht näher hervorgehobenen Ventilen und Anschlussmöglichkeiten für Hydraulikleitungen sichtbar, sowie eine auf einem Klemmenkasten 11 am Ölgehäuse 18 angeordnete Abdeckung mit Kühlrippen 13, beispielsweise für eine Aggregatssteuerung 12, mit der das Netzkabel 9 und das Steuerungskabel 7 lösbar verbunden sind, und die beispielsweise auch einen Ein/Aus-Schalter aufweist. Der Verteilerblock 10 und die Abdeckung 12 stehen durch eine Ausblasöffnung A1 des Außengehäuses 2 nach außen vor. Die Ausblasöffnung A1 weist einen inneren Rand 14 auf, der um die umgriffenen Komponenten einen Luftaustrittsspalt frei hält.From the inner oil housing 18 is in Fig. 1 a distributor block 10 mounted thereon with valves and connection options for hydraulic lines not further highlighted, and a cover with cooling fins 13 arranged on a terminal box 11 on the oil housing 18, for example for an aggregate control 12, with which the power cable 9 and the control cable 7 are detachably connected, and which also has, for example, an on / off switch. The distributor block 10 and the cover 12 project outwardly through an exhaust opening A1 of the outer housing 2. The exhaust opening A1 has an inner edge 14, which keeps an air outlet gap around the gripped components.

Das Außengehäuse 2 besteht beispielsweise aus zwei im Wesentlichen spiegelbildlichen Gehäusehälften 15, 16 aus Kunststoff und/oder Blech, die auch am unteren Ende 22 (Fig. 2) des Ölgehäuses 18 beispielsweise mit Schraubstandfüßen 17 zusätzlich festgelegt sind. Das so eingekleidete Motorpumpenaggregat M hat ein weitgehend geschlossenes, annähernd würfelförmiges Erscheinungsbild mit glatten Außenwänden.The outer housing 2 consists, for example, of two essentially mirror-inverted housing halves 15, 16 made of plastic and / or sheet metal which are also provided at the lower end 22 (FIG. Fig. 2 ) of the oil housing 18, for example, with Schraubstandfüßen 17 are additionally defined. The thus-clad motor pump unit M has a largely closed, approximately cube-shaped appearance with smooth outer walls.

Gemäß Fig. 2 ist das Ölgehäuse 18 beispielsweise ein stranggepresster Rohrabschnitt aus Leichtmetall oder einer Leichtmetalllegierung mit annähernd viereckigem und leicht gerundetem Außenumriss und in der gezeigten Ausführungsform vier Seitenwänden 19, die längs verlaufende Kühlrippen 20 aufweisen. Das Ölgehäuse 18 ist an oberen und unteren Enden 21, 21' durch Verschlussdeckel verschlossen und trägt an einer Seitenwand 19 den Verteilerblock 10 sowie den Klemmenkasten 11 mit der Abdeckung 12 für die Aggregatssteuerung. Im Ölgehäuse 18 ist mindestens ein Elektromotor, häufig ein offener Unter-Ölmotor, verbaut, der wenigstens eine Pumpe oder wenigstens ein Pumpenelement treibt (Drehstrom- oder Wechselstrom-Ausführung).According to Fig. 2 For example, the oil housing 18 is an extruded tube section of light metal or a light metal alloy with an approximately quadrangular and slightly rounded outer contour and, in the illustrated embodiment, four side walls 19 having longitudinal cooling fins 20. The oil housing 18 is closed at upper and lower ends 21, 21 'by cap and carries on a side wall 19 of the manifold block 10 and the terminal box 11 with the cover 12 for the unit control. In the oil housing 18 is at least one electric motor, often an open sub-oil engine installed, which drives at least one pump or at least one pump element (three-phase or AC version).

Erfindungsgemäß ist an zumindest einer Seitenwand 19 wenigstens ein Kühlgebläse G zwischen den oberen und unteren Enden 21, 21' angeordnet und z.B. am Ölgehäuse 18 oder im Außengehäuse 2 befestigt. Das Kühlgebläse G enthält in einer Außenverkleidung 22 beispielsweise mit quadratischem Endflansch einen elektrischen Antriebsmotor 23 und ein nicht näher hervorgehobenes Lüfterrad und ist an einer Seitenwand 19 montiert. Zur Montage kann ein C-förmiger Rahmen 24 benutzt werden, der sich zwischen Kühlrippen 20 an der Seitenwand 19 abstützt, und mit hinter Kühlrippen 20 angrenzender Seitenwände 19 eingehakten Befestigungshaken 25 festgelegt ist.According to the invention, at least one cooling fan G is arranged between the upper and lower ends 21, 21 'on at least one side wall 19 and fixed, for example, to the oil housing 18 or the outer housing 2. The cooling fan G contains in an outer lining 22, for example with a square end flange, an electric drive motor 23 and an unspecified highlighted fan and is mounted on a side wall 19. For mounting a C-shaped frame 24 may be used, which is located between cooling fins 20 on the side wall 19th supports, and hooked with rear fins 20 adjacent side walls 19 hooks 25 is fixed.

In der gezeigten Ausführungsform sind sogar zwei an voneinander abgewandten Seitenwänden 19 montierte Kühlgebläse G vorgesehen. Die Anzahl und Verteilung der Kühlgebläse G an den Seitenwänden 19 kann höher bzw. anders sein als gezeigt.In the illustrated embodiment, even two mounted on opposite side walls 19 cooling fan G are provided. The number and distribution of the cooling fans G on the side walls 19 may be higher or different than shown.

Im Außengehäuse 2, d.h. in jeder Gehäusehälfte 15, 16, sind in Ausrichtung auf das Kühlgebläse G Kühlluft-Einlässe 26 (Schlitze oder Löcher) geformt. In diesem Bereich kann gegebenenfalls ein Luftfilter montiert sein.In the outer casing 2, i. in each housing half 15, 16, cooling air inlets 26 (slots or holes) are formed in alignment with the cooling fan G. If necessary, an air filter can be installed in this area.

Ferner kann, wie an der linken Gehäusehälfte 16 in Fig. 2 angedeutet, im Bereich der Kühlluft-einlässe 26 ein innerer Rahmen 27 geformt sein, der bei montiertem Außengehäuse 2 (Fig. 1) über die Außenverkleidung 22 des dahinterliegenden Kühlgebläses G greift, so dass die angesaugte Luft zwangsgeführt wird.Further, as at the left half of the housing 16 in FIG Fig. 2 indicated in the region of the cooling air inlets 26, an inner frame 27 may be formed, which is mounted in the outer housing 2 (FIG. Fig. 1 ) engages over the outer lining 22 of the underlying cooling fan G, so that the sucked air is forcibly guided.

Jede Gehäusehälfte 15, 16 ist dreidimensional und zweckmäßig einstückig ausgebildet (z.B. ein Spritzgussformteil), kann jedoch auch aus einzelnen Abschnitten gefügt werden. Dabei weist jede Gehäusehälfte 15, 16 über mindestens drei Seitenwände 19 des Ölgehäuses 18 greifende Wände 28, 31, 40, 30, 29 auf, so dass das Ölgehäuse 18 praktisch an allen Seiten umschlossen ist. Alternativ könnte, falls zweckmäßig, das untere Ende 21' des Ölgehäuses 18 vom Außengehäuse 2 nicht abgedeckt sein. Über Öffnungen 35 in den Wandabschnitten 29 kann das Außengehäuse 2 zusätzlich am unteren Ende 21' festgelegt werden, d.h. nicht nur mit der Konsole 1 und den Befestigungsschrauben 33 am oberen Ende 21.Each housing half 15, 16 is three-dimensionally and expediently integrally formed (for example an injection-molded part), but can also be joined from individual sections. In this case, each housing half 15, 16 on at least three side walls 19 of the oil housing 18 cross-walls 28, 31, 40, 30, 29, so that the oil housing 18 is practically enclosed on all sides. Alternatively, if appropriate, the lower end 21 'of the oil housing 18 could not be covered by the outer housing 2. Via openings 35 in the wall sections 29, the outer housing 2 can be additionally fixed at the lower end 21 ', i. not only with the console 1 and the fixing screws 33 at the upper end 21st

Zweckmäßig sind zwischen dem Außengehäuse 2 und dem Ölgehäuse 18 elastische Kissen 34 eingesetzt.It is expedient to use elastic cushions 34 between the outer housing 2 and the oil housing 18.

Die vorderseitige Ausblasöffnung A1 mit dem Rand 14 wurde bereits anhand Fig. 1 erläutert. Fig. 2 verdeutlicht eine weitere Ausblasöffnung A2 an der Rückseite des Motorpumpenaggregats M, die von den Wandabschnitten 30, 31, 29 durch einen Rand 32 begrenzt ist und sich in montiertem Zustand des Außengehäuses 2 als vertikaler Schlitz weitgehend über die gesamte Länge des Ölgehäuses 18 erstreckt.The front-side blow-out opening A1 with the edge 14 has already been described Fig. 1 explained. Fig. 2 illustrates a further blow-out opening A2 at the rear of the motor pump unit M, which is bounded by the wall sections 30, 31, 29 by an edge 32 and extends in the mounted state of the outer housing 2 as a vertical slot largely over the entire length of the oil housing 18.

Das montierte Außengehäuse 2 dient nicht nur dem Schutz des Ölgehäuses 18, sondern auch der gezielten Kühlluftverteilung zumindest an den Seitenwänden 19, um die Kühlwirkung bei laufendem Kühlgebläse G zu intensivieren.The mounted outer housing 2 serves not only the protection of the oil housing 18, but also the targeted cooling air distribution at least on the side walls 19 in order to intensify the cooling effect when the cooling fan G is running.
