Abstract
Description
Die Erfindung betrifft ein Rückschlagventil mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The The invention relates to a check valve with the features of the preamble of claim 1.
Sie
geht von der deutschen Gebrauchsmusterschrift
Wird ein gattungsgemäßes Rückschlagventil in einer Brennkraftmaschine nicht in eine Kurbelgehäuseentlüftungsleitung eingebunden, sondern als direkte Verbindung zwischen dem Kurbelgehäusevolumen und dem Luftansaugsystem der Brennkraftmaschine, kann das Ventilplättchen aufgrund von Druckpulsationen im Kurbelgehäuse bzw. im Ansaugsystem kurzzeitig derart verformt werden, dass das Ventil öffnet, wenn es eigentlich in einer geschlossenen Stellung verharren sollte. Hierdurch kann es vorkommen, dass Öltröpfchen beim Betrieb der Brennkraftmaschine in falscher Richtung das Rückschlagventil durchlaufen.Becomes a generic check valve in an internal combustion engine not integrated in a crankcase ventilation line, but as a direct connection between the crankcase volume and the air intake system of the internal combustion engine, the valve plate due to of pressure pulsations in the crankcase or in the intake system for a short time be deformed so that the valve opens when it is actually in should remain in a closed position. This can be it Occur that oil droplets during Operation of the internal combustion engine in the wrong direction, the check valve run through.
Aufgabe der vorliegenden Erfindung ist es, eine Maßnahme aufzuzeigen, welche die Auswirkung von Druckpulsationen auf den Ventilkörper in Form eines Dichtelementes verringert.task The present invention is to show a measure which the effect of pressure pulsations on the valve body in shape a sealing element reduced.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 gelöst.These The object is achieved by the features in the characterizing part of the claim 1 solved.
Durch die erfindungsgemäße Ausgestaltung ist das Dichtelement von dynamischen Druckeinflüssen deutlich besser entkoppelt. Darüber hinaus bietet die erfindungsgemäße Ausgestaltung einen deutlich besseren Schutz für das Dichtelement vor Schmiermittelbewurf. Hierdurch wird die Schmiermittelbenetzung des Dichtelementes deutlich minimiert. Sollte es trotz der erfindungsgemäßen Ausgestaltung zu einer Schmiermittelbenetzung des Dichtelementes kommen und das Dichtelement aufgrund von Druckpulsationen entgegen der mittleren beidseitig anliegenden Druckverteilung öffnen, so wird deutlich weniger Schmiermittel in die falsche Richtung gefördert. Ferner führt die erfindungsgemäße Ausgestaltung zu einer Verbesserung der Dichtfunktion des Dichtelementes beim Brennkraftmaschinenbetrieb sowie zu einer deutlichen Reduzierung des Schmiermitteltransports in der falschen Richtung durch das Rückschlagventil.By the embodiment of the invention is significantly better decouples the sealing element from dynamic pressure influences. About that In addition, the embodiment of the invention provides a much better protection for the sealing element before lubricant grout. As a result, the lubricant wetting of the sealing element significantly minimized. It should be despite the inventive design come to a lubricant wetting of the sealing element and the Sealing element due to pressure pulsations against the middle open on both sides adjacent pressure distribution, so is significantly less Lubricant pumped in the wrong direction. Furthermore, the leads inventive design to improve the sealing function of the sealing element in Internal combustion engine operation and a significant reduction the lubricant transport in the wrong direction through the check valve.
Durch die Ausgestaltung gemäß Patentanspruch 2 wird der Schmiermittelgehalt an der Belüftungs- und der Kondensatablauföffnung minimiert.By the embodiment according to claim 2, the lubricant content at the vent and condensate drain ports is minimized.
Die Ausgestaltungen gemäß den Patentansprüchen 3 bis 5 stellen besonders bevorzugte Ausführungsbeispiele dar.The Embodiments according to claims 3 to 5 represent particularly preferred embodiments.
Die Größenordnungen gemäß Patentanspruch 6 und 7 haben sich in Versuchen als besonders vorteilhaft herausgestellt.The orders of magnitude according to claim 6 and 7 have been found in experiments to be particularly advantageous.
Die Ausgestaltung gemäß den Patentansprüchen 7 und 8 führt zu einer besseren Trennung der Transportwege von Leckagegas und Kondensat.The Embodiment according to claims 7 and 8 leads to a better separation of the transport routes of leakage gas and Condensate.
Im Folgenden ist die Erfindung anhand eines bevorzugten Ausführungsbeispieles in einer einzigen Figur näher erläutert.in the The invention is based on a preferred embodiment in a single figure closer explained.
