Abstract
Description
Die Erfindung betrifft ein insbesondere für ein Kurbelgehäuse einer Hubkolbenmaschine geeignetes Lüftungsventil.The The invention relates to a particular for a crankcase a Reciprocating engine suitable ventilation valve.
Beim Betrieb von Hubkolbenmaschinen können Verbrennungsgase zwischen den Zylindern und den Kolbenringen der Kolben in das Kurbelgehäuse der Hubkolbenmaschine entweichen. Durch diese auch als Blow-By-Gase bezeichneten Verbrennungsgase können sich innerhalb des Kurbelgehäuses beträchtliche Drücke aufbauen, so dass eine Entlüftung des Kurbelgehäuses erforderlich ist. Da die Blow-By-Gase infolge ihres Hindurchtritts durch den Kurbelraum mit Motoröl belastet sind, dürfen sie nicht mehr in die Umgebung abgegeben werden und werden deshalb gewöhnlich zuerst durch einen Ölabscheider hindurch geführt und dann in den Ansaugluftstrom der Hubkolbenmaschine eingeleitet, um sie von dort in die Brennräume der Zylinder zuzuführen. Zwischen dem Kurbelraum und einem Saugrohr oder einer anderen Stelle im Ansaugtrakt der Hubkolbenmaschine ist dazu häufig ein sogenanntes PCV(Positive Crankcase Ventilation)-Ventil vorgesehen, über das mittels des Unterdrucks im Ansaugtrakt Gase aktiv aus dem Kurbelraum in den Ansaugtrakt abgesaugt werden. Um den Druck im Kurbelgehäuse auf einen konstanten vorbestimmten Wert zu regeln, kann zudem ein Druckregelventil vorgesehen oder mit dem PCV-Ventil kombiniert sein.At the Operation of reciprocating engines can Combustion gases between the cylinders and the piston rings of Piston in the crankcase of the Reciprocating engine escape. Through these also as blow-by gases designated combustion gases can inside the crankcase considerable pressures build up so that a vent of the crankcase is required. Since the blow-by gases due to their passage through the crankcase with engine oil are loaded they are no longer released into the environment and therefore will usually first through an oil separator passed through and then introduced into the intake air flow of the reciprocating engine, from there to the combustion chambers to feed the cylinder. Between the crankcase and a suction pipe or other point in the intake the reciprocating engine is common a so-called PCV (Positive Crankcase Ventilation) valve provided over the by means of the negative pressure in the intake tract gases active from the crankcase be sucked into the intake system. To the pressure in the crankcase on a Constant predetermined value can also control a pressure control valve be provided or combined with the PCV valve.
Da die Blow-By-Gase neben Öl auch Wasser und Schmutzpartikel enthalten, kann es gegebenenfalls zu einer Vereisung oder Blockierung des PCV-Ventils und/oder des Druckregelventils kommen, so dass die Blow-By-Gase nicht mehr ordnungsgemäß aus dem Kurbelraum entweichen können und sich in diesem ein unerwünschter Über- oder auch Unterdruck aufbauen kann.There the blow-by gases next to oil may also contain water and dirt particles, it may to icing or blocking the PCV valve and / or the Pressure control valve come so that the blow-by gases are no longer properly out of the Crank room can escape and in this an unwanted over- or even Can build up underpressure.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein Lüftungsventil bereit zu stellen, das im Falle eines Überdrucks im Kurbelraum eine Zwangsentlüftung und im Falle eines Unterdrucks eine Belüftung des Kurbelraums ermöglicht.outgoing This is the object of the invention, a ventilation valve to provide that in the event of overpressure in the crankcase a forced ventilation and in the case of a negative pressure ventilation of the crankcase allows.
Diese Aufgabe wird erfindungsgemäß durch ein Lüftungsventil für ein Kurbelgehäuse einer Hubkolbenmaschine gelöst, das zur Montage zwischen einem Kurbelraum des Kurbelgehäuses und einem Ansaugtrakt der Hubkolbenmaschine vorgesehen ist, zur Belüftung des Kurbelgehäuses öffnet, wenn der Druck im Ansaugtrakt den Druck im Kurbelraum übersteigt, zur Entlüftung des Kurbelgehäuses öffnet, wenn eine positive Druckdifferenz zwischen dem Druck im Kurbelraum und dem Druck im Ansaugtrakt einen vorgegebenen Wert übersteigt, und geschlossen bleibt, solange die positive Druckdifferenz den vorgegebenen Wert nicht übersteigt.These The object is achieved by a vent valve for a crankcase solved a reciprocating engine, that for mounting between a crankcase of the crankcase and an intake tract of the reciprocating engine is provided for ventilation of the Crankcase opens when the pressure in the intake tract exceeds the pressure in the crankcase, for venting of the crankcase opens when a positive pressure difference between the pressure in the crankcase and the pressure in the intake tract exceeds a predetermined value, and remains closed as long as the positive pressure difference is the predetermined Value does not exceed.
Um die Zwangsentlüftung im Falle eines Überdrucks im Kurbelraum zu erreichen, weist das Ventil vorzugsweise ein Ventilglied und eine Ventilfeder auf, die das Ventilglied von der Seite des Ansaugtrakts her gegen einen Ventilsitz anpresst, um das Ventil geschlossen zu halten. Der Anpressdruck der Ventilfeder entspricht der positiven Druckdifferenz, bei der das Ventil öffnet. Wenn der Druck im Kurbelraum zum Beispiel infolge einer Vereisung oder Blockierung der regulären Entlüftungsöffnungen über einen der positiven Druckdifferenz entsprechenden Wert ansteigt, wird das Ventilglied vom Ventilsitz abgehoben und dadurch eine Begrenzung des Drucks im Kurbelgehäuse sichergestellt.Around the forced ventilation in case of overpressure reach in the crankcase, the valve preferably has a valve member and a valve spring on which the valve member from the side of Intake tract forth against a valve seat presses to the valve to keep closed. The contact pressure of the valve spring corresponds the positive pressure difference at which the valve opens. If the pressure in the crankcase, for example due to icing or Blocking the regular Vents over one the positive pressure difference corresponding value increases is lifted the valve member from the valve seat, thereby limiting the pressure in the crankcase ensured.
Zur Belüftung des Kurbelraums enthält das Ventilglied des Ventils vorzugsweise mindestens eine Öffnung, die auf der Seite des Kurbelraums durch eine Membran verschlossen ist, welche sich unter Freigabe der Öffnung elastisch verformt, wenn der Druck im Ansaugtrakt den Druck im Kurbelraum übersteigt, während sie in einem unverformten Zustand dichtend gegen das Ventilglied anliegt, wenn der Druck im Kurbelgehäuse dem Druck im Ansaugtrakt entspricht oder diesen übersteigt.to ventilation of the crankcase contains the valve member of the valve preferably at least one opening, which is closed on the side of the crankcase by a membrane is, which deforms elastically upon release of the opening, if the pressure in the intake tract exceeds the pressure in the crankcase, while they seal against the valve member in an undeformed state is applied when the pressure in the crankcase to the pressure in the intake equals or exceeds this.
Zweckmäßig wird das Lüftungsventil in einem bereits vorhandenen Lüftungskanal montiert, der ein den Druck im Kurbelraum regelndes Druckregelventil und/oder ein PCV-Ventil mit dem Ansaugtrakt der Hubkolbenmaschine verbindet, wobei es vorzugsweise über einer Einmündung eines mit dem Kurbelraum kommunizierenden Be- und Entlüftungskanals verbaut wird.It is useful the ventilation valve in an existing ventilation duct mounted, which regulates the pressure in the crankcase pressure regulating valve and / or a PCV valve connects to the intake of the reciprocating engine, preferably over a junction a communicating with the crankcase ventilation and exhaust duct is installed.
Das erfindungsgemäße Lüftungsventil kann nicht nur zur Belüftung und Zwangsentlüftung eines Kurbelgehäuses einer Hubkolbenmaschine eingesetzt werden, sondern auch bei anderen Anwendungen, wo ein Ventil benötigt wird, das gleichzeitig in einer Richtung als Überduckventil und in der anderen Richtung Belüftungsventil arbeiten soll. Allgemein umfasst ein solches Ventil erfindungsgemäß ein Ventilglied und eine Ventilfeder, die das Ventilglied gegen einen Ventilsitz presst, wobei das Ventilglied mindestens eine Öffnung und eine elastisch verformbare Membran aufweist, die auf der von der Ventilfeder abgewandten Seite des Ventilgliedes über der Öffnung angeordnet ist und diese in unverformtem Zustand dicht verschließt.The Ventilation valve according to the invention not only for ventilation and forced ventilation a crankcase a reciprocating engine are used, but also in others Applications where a valve is needed that is simultaneously in one direction as Überduckventil and in the other direction vent valve should work. Generally, such a valve according to the invention comprises a valve member and a valve spring which holds the valve member against a valve seat presses, wherein the valve member at least one opening and an elastically deformable membrane which, on the side facing away from the valve spring of the Valve member over the opening arranged is and closes tightly in undeformed state.
Gemäß einer bevorzugten Ausgestaltung der Erfindung kann der Volumenstrom durch das als Belüftungsventil arbeitende Ventil auf einen gewünschten Maximalwert begrenzt werden, zum Beispiel indem entweder der Öffnungsquerschnitt der Öffnung begrenzt wird oder indem man durch geeignete Materialwahl oder Abmessungen der Membran den von der verformten Membran freigegebenen Öffnungsquerschnitt begrenzt.According to a preferred embodiment of the invention, the volume flow can be limited by the valve acting as a vent valve to a desired maximum value, for example play by either the opening cross-section of the opening is limited or by limited by appropriate choice of material or dimensions of the membrane released from the deformed membrane opening cross-section.
Zweckmäßig umfasst das Ventilglied einen scheibenförmigen Ventilteller, der mehrere im Winkelabstand voneinander um seine Mittelachse herum angeordnete Öffnungen aufweist. Die Öffnungen werden auf der von der Ventilfeder abgewandten Seite des Ventiltellers vorzugsweise von der ebenfalls scheibenförmigen Membran überdeckt, die mit ihrer Mitte zweckmäßig unterhalb der Mitte des Ventiltellers befestigt ist, sich in radialer Richtung über die Öffnungen hinaus erstreckt und dichtend gegen den Ventilteller anliegt, entweder mit ihrer gesamten, dem Ventilteller zugewandten Breitseitenfläche oder nur mit ihrem ringförmigen Umfangsrand, der jenseits der Öffnungen in Richtung des Ventiltellers umgebogen ist.Appropriately includes the valve member is a disk-shaped Valve plate, the several angularly spaced from each other around his Center axis arranged around openings having.
