Description

Die Erfindung betrifft eine Baugruppe für eine von einer Brennkraftmaschine angetriebene Apparatur gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an assembly for a driven by an internal combustion engine Apparatus according to the preamble of claim 1.

Derartige Baugruppen sind z. B. aus dem deutschen Gebrauchsmuster 1 883 625 bekannt. Es wird eine Ventileinrichtung zur Verbindung der Ansaugleitung oder einer Unterdruckzone eines Vergasers mit dem Kurbelgehäuse eines Verbrennungsmotors beschrieben, wobei Gase, die am Motorkolben vorbei in das Kurbelgehäuse gedrungen sind, in die Motorzylinder zurückgeführt und zusammen mit dem von dem Vergaser erzeugten, brennbaren Gemisch verbraucht werden.Such assemblies are such. B. known from German utility model 1 883 625. It becomes a valve device for connecting the suction line or a vacuum zone of a carburetor with the crankcase of an internal combustion engine, wherein gases, that penetrated past the engine piston into the crankcase, into the engine cylinders returned and together with the combustible mixture generated by the carburetor be consumed.

Weiterhin ist eine derartige Ventileinheit aus der US PS 3 139 080 bekannt, die Mittel zur Beseitigung von Kurbelgehäusegasen beschreibt, da diese Kurbelgehäusegase als Quelle von Luftverunreinigungen gelten.Furthermore, such a valve unit is known from US Pat. No. 3,139,080, the means for Eliminates crankcase gases as describes these as crankcase gases as a source of Air pollution applies.

Will man solche Baugruppen nun in modernen Kraftfahrzeugen oder anderen mit Brennkraftmaschinen betriebenen Apparaturen einsetzen, so ist daran nachteilig, daß die bekannten Baugruppen über entsprechende Außenabmessungen verfügen sowie über ein entsprechend hohes Eigengewicht.Do you want such assemblies now in modern motor vehicles or others Use internal combustion engine operated equipment, it is disadvantageous that the known assemblies have appropriate external dimensions and a correspondingly high weight.

Man könnte nun die Bauteilgröße weiterhin verkleinern, was zu einer Gewichtsreduzierung führen würde. Aber auch dabei ist nachteilig, daß die räumliche Ausdehnung aufgrund der verschiedenen Einzelaggregate und deren Verbindungsleitungen sowie das Gewicht durch eine geringe Integrationsdichte hoch ist.You could now further reduce the component size, which leads to a reduction in weight would lead. But it is also disadvantageous that the spatial expansion due to the various individual units and their connecting lines as well as the weight by one low integration density is high.

Aus der US-A-4 169 432 ist eine Einrichtung zum Regeln des Kurbegehäusedruckes bekannt, hierzu ist eine Leitung für den Kurbelgehäusegaseinlaß vorhanden und zwar durch den Zylinderkopf. Die Leitung zur Ölwanne gemäß diesem Stand der Technik läßt einen Fluß in Richtung zur Ölwanne zu. Ein Nachteil der dargestellten Einrichtung ist der hohe Montage- und Einzelkomponentenaufwand.From US-A-4 169 432 a device for regulating the crankcase pressure is known, there is a line for the crankcase gas inlet through the Cylinder head. The line to the oil pan according to this prior art allows a flow in Direction to the oil pan. A disadvantage of the device shown is the high assembly and single component effort.

Es ist ferner aus der EP-A-0 459 031 eine Baugruppe bekannt bei der verschiedene Vorrichtungen kombiniert werden. Allerdings zeigt diese Baugruppe dem Fachmann nicht ein komplettes Modul mit dem auch die Möglichkeit besteht insbesondere im unteren Drehzahlbereich der Verbrennungskraftmaschine eine optimale Abführung der Kurbelgehäusegase zu erzielen.It is also known from EP-A-0 459 031 an assembly in which various Devices can be combined. However, this assembly does not show the expert Complete module with which there is also the possibility, especially in the lower one Speed range of the internal combustion engine optimal discharge of Achieve crankcase gases.

Es ist somit Aufgabe der Erfindung, eine Baugruppe der eingangs genannten Art dahingehend zu verbessern, daß eine Baugruppe entsteht, die einfacher zu montieren, leichter, billiger und kompakter ist.It is therefore an object of the invention to provide an assembly of the type mentioned to improve that an assembly is created that is easier to assemble, lighter, cheaper and is more compact.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß Bauteile zu einem Modul zusammengefaßt sind und daß Mittel vorgesehen sind, mit denen das Modul mit der Brennkraftmaschine verbindbar ist. Von Vorteil ist hierbei, daß sowohl die Herstellungskosten der einzelnen Funktionseinheiten als auch die Kosten der Endmontage sowie das Gewicht reduziert werden können. Aufgrund der konstruktiven Durchgängigkeit werden Synergien zwischen den verschiedenen Funktionseinheiten erreicht, die zur genannten Kosteneinsparung beitragen. Die Bereitstellung von Modulen für die Endmontage vereinfacht außerdem die Logistik. Der modulare Aufbau der Baueinheit wirkt sich außerdem günstig auf das Recycling der Baugruppen aus. Die Zusammenfassung der Funktionseinheiten zu einem Modul gestattet darüber hinaus ein schnelles Reagieren auf veränderte Marketingkonzepte.According to the invention, this object is achieved in that components form a module are summarized and that means are provided with which the module with the Internal combustion engine is connectable. The advantage here is that both the manufacturing costs of the individual functional units as well as the costs of final assembly and the weight can be reduced. Due to the structural consistency, synergies are created achieved between the various functional units that lead to the above-mentioned cost savings contribute. The provision of modules for final assembly also simplifies the Logistics. The modular structure of the unit also has a positive effect on recycling of the assemblies. The functional units can be combined into one module in addition, a quick reaction to changed marketing concepts.

Die Erfindung sieht ferner vor, daß im Modul ein Trägerkörper integriert ist, der mit der Brennkraftmaschine verbindbar ist und an dem die Bauteile des Moduls befestigt sind. Dieser Trägerkörper gibt dem Modul eine Struktur, die einerseits die Verbindung des Moduls mit der Brennkraftmaschine definiert als auch die Anordnung der einzelnen Bauteile des Moduls. Eine Möglichkeit wäre beispielsweise, den Luftfilterkasten als Trägerkörper zu verwenden.The invention further provides that a carrier body is integrated in the module, which with the Internal combustion engine is connectable and to which the components of the module are attached. This Carrier body gives the module a structure that connects the module with the one hand Internal combustion engine also defines the arrangement of the individual components of the module. A It would be possible, for example, to use the air filter box as a carrier body.

Weiterhin sieht die Erfindung vor, daß das Modul als Bauteil im wesentlichen ein Kurbelgehäusedruckregelventil und ein Leerlaufunterdruckventil enthält, die in einer einzigen Funktionseinheit zusammengefaßt sind, was sowohl zu Gewichts- als auch zu Kosteneinsparungen führt.Furthermore, the invention provides that the module is essentially a component Includes crankcase pressure control valve and an idle vacuum valve, all in one Functional unit are summarized, leading to both weight and Cost savings leads.

Die Vorrichtung kommuniziert mit dem Kurbelgehäuse und/oder dem Filterraum, insbesondere mit dessen Reinluftseite. Dies garantiert, daß die für Emissionen verantwortlichen Kurbelgehäusegase im Gesamtsystem der Brennkraftmaschine verbleiben und dem Verbrennungsvorgang zugeführt werden.The device communicates with the crankcase and / or the filter space, in particular with its clean air side. This guarantees that those responsible for emissions Crankcase gases remain in the overall system of the internal combustion engine and that Combustion process are fed.

Das Kurbelgehäusedruckregelventil und/oder das Leerlaufunterdruckventil sind mit dem Saugrohr und dem Kurbelgehäuse verbindbar angeordnet. Durch diese Anordnung ist sichergestellt, daß die Kurbelgehäusegase im Kreislauf des Motors des Kraftfahrzeuges verbleiben.The crankcase pressure control valve and / or the idling vacuum valve are with the Intake pipe and the crankcase arranged connectable. Because of this arrangement ensured that the crankcase gases in the circuit of the engine of the motor vehicle remain.

Der Vorteil liegt im Zusammenfassen von Funktionsgruppen, die in einem Wirkzusammenhang stehen, da auf diese Weise sowohl Kommunikationswege, Gehäuseabmessungen als auch das zu betrachtende Gesamtgewicht der Baugruppe abnehmen.A further development of the invention provides that the module as a further Component an oil filler neck and / or an oil dipstick and / or an AKF valve, as shown in German patent specification 42 05 101 in claims 2-5 and in the description, Column 1, line 51 to column 2, line 13 is described and / or a throttle valve and / or whose actuating device comprises. The advantage lies in the combination of functional groups, that are in an effective context, because in this way both communication channels, Take off the housing dimensions and the total weight of the assembly to be considered.

In einer anderen vorteilhaften Weiterbildung der Erfindung ist vorgesehen, daß das Kurbelgehäusedruckregelventil als Trägerkörper des Moduls wirkt, mittels dessen das Modul mit der Brennkraftmaschine verbindbar ist. Der Vorteil als Strukturkörper des Moduls liegt in seiner räumlichen Ausdehnung sowie in seiner Funktionsweise, die ohnehin einen direkten Kontakt zum Gehäuse der Brennkraftmaschine als vorteilhaft erscheinen läßt, begründet sowie in der Tatsache, daß es über eine gewisse Grundfestigkeit des Gehäuses verfügt.Another advantageous development of the invention provides that the crankcase pressure control valve acts as the carrier body of the module, by means of which the module with the Internal combustion engine is connectable. The advantage as a structural body of the module lies in its spatial extension as well as in its functionality, which is a direct contact anyway to the housing of the internal combustion engine may appear advantageous, justified and in the The fact that it has a certain basic strength of the housing.

In einer alternativen Ausgestaltung sind die Ventilsitze sowohl vom Kurbelgehäusedruckregelventil als auch vom Leerlaufunterdruckventil beheizbar. Dies geschieht mittels eines elektrisch betriebenen Heizwiderstandes, der derart angebracht ist, daß die Sitzflächen im Frostfall erwärmen, so daß ein Funktionsausfall des Ventils im Winter unmöglich wird. Versorgt wird der Heizwiderstand über das elektrische Bordnetz des Fahrzeugs. Sinkt die Umgebungstemperatur auf Werte um oder unter Null Grad, so gibt ein Thermoelement ein Signal an die Bordsteuerung, in der ein Steuersignal generiert wird, das den Heizwiderstand im Ventilsitz aktiviert, so daß derartige Ventile auch bei Temperaturen um oder unter dem Nullpunkt einsatzfähig bleiben. In einer speziellen Ausgestaltung besteht der beheizbare Sitz eines derartigen Ventils, z. B. aus einem Kupferblech.In an alternative embodiment, the valve seats are both from the crankcase pressure control valve as well as heated by the idle vacuum valve. This is done using a electrically operated heating resistor, which is attached such that the seats in Warm up the frost in order to prevent the valve from failing in winter. The heating resistor is supplied via the vehicle's electrical system. Sinks Ambient temperature to values around or below zero degrees, so enters a thermocouple Signal to the on-board control, in which a control signal is generated, which the heating resistor in Valve seat activated, so that such valves even at temperatures around or below Zero point remain operational. The heatable seat is in a special embodiment such a valve, e.g. B. from a copper sheet.
