Abstract
Bei einer Brennkraftmaschine mit einem Turbolader muß eine Kurbelgehäuseentlüftung sowohl über einen ersten Entlüftungsleitungsabschnitt mit einem Ansaugrohr stromauf des Turboladers als auch über einen zweiten Entlüftungsleitungsabschnitt mit dem Ansaugrohr stromab des Turboladers verbunden sein. Bei bekannten Vorrichtungen zur Kurbelgehäuseentlüftung ist in dem ersten Entlüftungsleitungsabschnitt ein Druckregelventil und in dem zweiten Entlüftungsleitungsabschnitt ein weiteres Druckregelventil oder eine Blende vorgesehen. DOLLAR A Erfindungsgemäß wird vorgeschlagen, den ersten Entlüftungsleitungsabschnitt (8.1) und den zweiten Entlüftungsleitungsabschnitt (8.2) an ein einziges Druckregelventil (2) anzuschließen. DOLLAR A Das erfindungsgemäße Druckregelventil (2) hat einen mit einem Ventilkörper zusammenwirkenden Ventilsitz (53), der einen ersten Ausgangskanal (29) und einen zweiten Ausgangskanal (30) aufweist. Der zweite Ausgangskanal (30) ist konzentrisch um den ersten Ausgangskanal (29) herum angeordnet.In an internal combustion engine with a turbocharger, a crankcase ventilation must be connected both to a suction pipe upstream of the turbocharger via a first ventilation pipe section and to the suction pipe downstream of the turbocharger via a second ventilation pipe section. In known devices for crankcase ventilation, a pressure control valve is provided in the first ventilation line section and a further pressure control valve or an orifice is provided in the second ventilation line section. DOLLAR A According to the invention, it is proposed to connect the first vent line section (8.1) and the second vent line section (8.2) to a single pressure control valve (2). DOLLAR A The pressure control valve (2) according to the invention has a valve seat (53) which interacts with a valve body and has a first output channel (29) and a second output channel (30). The second output channel (30) is arranged concentrically around the first output channel (29).
Description
Stand der TechnikState of technology
Die Erfindung geht aus von einem Druckregelventil nach der Gattung des Hauptanspruchs.The invention is based on one Pressure control valve according to the type of the main claim.
Aus der
Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Druckregelventil mit den kennzeichnenden Merkmalen des Hauptanspruchs hat dem gegenüber den Vorteil, daß auf einfache Art und Weise eine Verbesserung gegenüber dem Stand der Technik dadurch erzielt wird, daß nur ein einziges Druckregelventil für den ersten Entlüftungsleitungsabschnitt und den zweiten Entlüftungsleitungsabschnitt erforderlich ist. Auch eine Blende in dem zweiten Entlüftungsleitungsabschnitt kann entfallen. Dies wird erreicht, indem der Ventilsitz des erfindungsgemäßen Druckregelventils einen ersten Ausgangskanal und einen zweiten Ausgangskanal aufweist.The pressure control valve according to the invention with the characteristic features of the main claim compared to the Advantage that on simple way an improvement over the prior art is achieved that only one only pressure control valve for the first vent line section and the second vent line section is required. Also an orifice in the second vent line section can be omitted. This is achieved by the valve seat of the pressure control valve according to the invention has a first output channel and a second output channel.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Druckregelventils möglich.By the measures listed in the subclaims are advantageous developments and improvements of the main claim specified pressure control valve possible.
Besonders vorteilhaft ist es, den ersten Ausgangskanal zentrisch auf einer Achse und den zweiten Ausgangskanal konzentrisch zum ersten Ausgangskanal und ringförmig außen um den ersten Ausgangskanal anzuordnen, da dies eine besonders günstige Anordnung ist, da mit dem Ventilkörper dadurch gleichzeitig der erste Ausgangskanal und der zweite Ausgangskanal verschlossen werden kann.It is particularly advantageous first output channel centered on an axis and the second output channel concentric to the first output channel and ring-shaped outside around the first output channel to arrange, since this is a particularly favorable arrangement, because with the valve body thereby the first output channel and the second output channel simultaneously can be locked.
Auch vorteilhaft ist, wenn der Querschnitt des ersten Ausgangskanals kleiner ist als der Querschnitt des zweiten Ausgangskanals, da der Unterdruck in dem ersten Ausgangskanal außerhalb des Betriebs des Turboladers mit beispielsweise 600 mbar deutlich größer ist als der Unterdruck in dem zweiten Ausgangskanal bei Betrieb des Turboladers mit beispielsweise 100 mbar. Um zu erreichen, daß in allen Betriebszuständen die aus dem Unterdruck resultierende auf den Ventilkörper wirkende Kraft nahezu gleich ist, muß der Querschnitt und damit die Fläche des zweiten Ausgangskanals im Verhältnis umgekehrt proportional größer sein als der Querschnitt des ersten Ausgangskanals.It is also advantageous if the cross section of the first output channel is smaller than the cross section of the second Output channel, because the negative pressure in the first output channel outside the operation of the turbocharger with, for example, 600 mbar is bigger than the negative pressure in the second outlet channel when the Turbocharger with, for example, 100 mbar. To achieve that in all operating conditions that resulting from the vacuum acting on the valve body Force is almost the same Cross section and therefore the area of the second output channel is inversely proportional to be taller than the cross section of the first output channel.
Desweiteren vorteilhaft ist, an den ersten Ausgangskanal einen ersten Ausgangsanschluß mit einem ersten Rückschlagventil und an den zweiten Ausgangskanal einen zweiten Ausgangsanschluß mit einem zweiten Rückschlagventil anzuordnen, um zum einen zu verhindern, daß das Kurbelgehäuse bei Betrieb des Turboladers mit vom Turbolader aufgebauten Druck beaufschlagt wird und zum anderen einen Kurzschlußstrom von dem Ansaugrohr stromauf des Turboladers über das Druckregelventil in das Ansaugrohr stromab des Druckregelventils zu unterbinden.It is also advantageous to the first output channel a first output connection with a first check valve and to the second output channel a second output terminal with a second check valve to arrange to prevent the crankcase from operating pressure of the turbocharger built up by the turbocharger is and on the other hand a short circuit current from the intake pipe upstream of the Turbocharger over the pressure control valve into the intake pipe downstream of the pressure control valve to prevent.
Auch vorteilhaft ist, wenn das Druckregelventil als Membranventil mit einer Membran ausgebildet ist, da ein Membranventil äußerst preisgünstig herzustellen, zuverlässig und raumsparend ist.It is also advantageous if the pressure control valve is designed as a diaphragm valve with a diaphragm, since a diaphragm valve is extremely inexpensive to manufacture, reliable and is space-saving.
Darüber hinaus vorteilhaft ist, wenn das Druckregelventil einteilig mit einer Ölabscheidevorrichtung verbunden ist, da auf diese Weise eine äußerst kompakte, platzsparende und montagefreundliche Anordnung erzielt wird.It is also advantageous when the pressure control valve is integrally connected to an oil separator is because in this way an extremely compact, space-saving and assembly-friendly arrangement is achieved.
Es kann aber auch vorteilhaft sein, aus Gründen der Geometrie der Brennkraftmaschine das Druckregelventil separat und von anderen Vorrichtungen getrennt vorzusehen.But it can also be advantageous for reasons the geometry of the internal combustion engine, the pressure control valve separately and to be provided separately from other devices.
