Abstract
Description
Haupt-Nebenstrom-Druckfilter (H-N-D-Filter) für Ver brennungsmotoren (Ölfilter).Main bypass pressure filter (H-N-D filter) for Ver internal combustion engines (oil filters).
Der H-N-D-Filter für Verbrennungsmotoren besteht aus einem gemeinsamen Gehäuse mit Zu- und Ablauf. Das Schmieröl wird durch Öffnungen zum Hauptstromfilter gepumpt. Der Hauptstromfilter besteht aus getränktem, speziellem Faltpapier von ca. 20 micron und wird radial durchströmt. Im Hauptstromfilter ist ein Umgehungsventil. Dieses öffnet, wenn der Hauptstromfilter so verschmutzt ist, daß er verstopft. Der Hauptstromfilter ist gekapselt. Vom Hauptstromfilter zum Nebenstromfilter, er besteht aus aufgerolltem Papier (Papier- Rollbandfilter) oder einem anderen Filtermaterial mit einer Filterfeinheit von unter 1 micron, sind Red.- Öffnungen angebracht. Von den Red.-Öffnungen fließt das Schmieröl außen am Papier-Rollbandfilter entlang und drückt ihn durch den Systemdruck zusammen, so daß sich keine Kanäle bilden können. Anschließend wird das Schmieröl axial durch den Nebenstromfilter gedrückt. Bei Einsatz von Papier-Rollbandfiltern wird Feuchtigkeit im Nebenstromfilter gespeichert. Der Rücklauf des Nebenstromfilters wird über eine Verbindung zum Rücklauf des Hauptstromfilters geleitet. Der gesamte H-N-D-Filter wird, wenn die Filterkapazität erreicht ist, ausgetauscht. Der H-N-D-Filter läßt sich besonders bei Motoren mit Öl-Schraubfiltern einsetzen. Die Größe des H-N-D-Filters richtet sich nach der vor geschriebenen Ölmenge im Motor. Bei einer anderen Kon struktion kann der Hauptstromfilter und der Nebenstromfilter übereinander in einem gemeinsamen Gehäuse untergebracht werden. The H-N-D filter for internal combustion engines consists of a common housing with inlet and outlet. The Lubricating oil becomes the main flow filter through openings pumped. The main flow filter consists of impregnated, special folding paper of approx. 20 micron and becomes radial flows through. There is a bypass valve in the main flow filter. This opens when the main flow filter is so dirty is that it clogs up. The main flow filter is encapsulated. From the main flow filter to the secondary flow filter, it consists of rolled paper (paper Rollbandfilter) or another filter material with a filter fineness of less than 1 micron, Red.- Openings attached. From the Red. Openings flows the lubricating oil along the outside of the paper belt filter and compresses it by the system pressure so that no channels can form. Then that will Lubricating oil pressed axially through the bypass filter. When using paper roll belt filters, moisture becomes stored in the bypass filter. The return of the bypass filter is connected to the Return of the main flow filter passed. The whole H-N-D filter will when the filter capacity is reached is exchanged. The H-N-D filter is special for engines with oil screw filters. The The size of the H-N-D filter depends on the written amount of oil in the engine. In another con the main flow filter and the secondary flow filter one above the other in a common housing will.
Die Standzeit des H-N-D-Filters ist durch die extrem große Filterfläche des Nebenstrom-Tiefbettfilters (Papier-Rollbandfilter) 3- bis 5mal so lang (Kosten ersparnis). Da die ständigen Ölwechsel wegfallen (erst nach ca. 100 000 bis 120 000 km), muß nur das verbrauchte Öl nachgefüllt werden. Dadurch werden bis ca. 90% Schmieröl eingespart. Dies bedeutet eine geringere Entsorgung an Altöl.The service life of the H-N-D filter is extreme large filter area of the bypass low-bed filter (Paper roll belt filter) 3 to 5 times as long (cost savings). Because the constant oil changes are no longer necessary (only after approx. 100,000 to 120,000 km), only that used oil can be refilled. This will up to 90% of lubricating oil saved. This means one less waste oil disposal.
Der Verschleiß des Motors durch Rückstände im Schmieröl ist sehr gering.The wear of the engine through residues in the Lube oil is very low.
Bei Einsatz des H-N-D-Filters gibt es nur Vorteile, die die Mehrkosten des Filters bei weitem übertreffen. Die Lebensdauer des Motors verlängert sich erheblich und die Betriebskosten werden stark reduziert.When using the H-N-D filter, there are only advantages that far exceed the additional cost of the filter. The lifespan of the engine is extended considerably and the operating costs are greatly reduced.

Der von mir entwickelte Haupt-Nebenstrom-Druckfilter (H-N-D-Filter) für gleichen Einsatz hat einen zu sätzlichen Tiefenfilter (Papier-Rollbandfilter oder anderes Filtermaterial) im Nebenstrom, der axial durchströmt wird, mit einer Filterfeinheit unter 1 micron. Dadurch wird für den H-N-D-Filter eine Filterfeinheit um 1 micron erreicht. Außerdem wird Feuchtigkeit (Säure, Wasser) im Nebenstromfilter, bei Einsatz von Papier-Rollbandfiltern, gespeichert.A commercially available oil filter for internal combustion engines consists of a filter made of special folded paper or other filter material, which is flowed through radially with a filter fineness of approx. 20 micron.
The main bypass pressure filter (HND filter) developed by me for the same application has an additional depth filter (paper roll belt filter or other filter material) in the bypass, which is flowed through axially, with a filter fineness below 1 micron. This achieves a filter fineness of 1 micron for the HND filter. Moisture (acid, water) is also stored in the bypass filter when using paper roll belt filters.
