Ölkühleinriehtung an Brennkraftmaschinen.
Den Gegenstand der Erfindung bildet eine Ölkühleinrichtung an Brennkraftmaschinen, besonders für Feuerspritzen, die in der Zeichnung in zwei Ausführungsbeispielen veranschaulicht ist. Es zeigen Fig. 1 und 2 die untere Hälfte eines mit der Kühleinrichtung gemäss der Erfindung versehenen Kurbelgehäuses im Längs-und Querschnitt ; Fig. 3 stellt eine andere Ausführungsform im Querschnitt dar.
Gemäss Fig. 1 und 2 sind in dem in der Längsrichtung aufsteigend ausgebildeten Doppelboden des Kurbelgehäuses zwei voneinander getrennte, in der Längsrichtung verlaufende Kanäle 1, 2 vorgesehen, die an dem höher gelegenen Ende miteinander durch einen Querkanal 3 und am unteren Ende mit der Kühlwasserumlaufrohrleitung verbunden sind. Der Boden ist vorzugsweise oben mit Querrippen 4 und unten mit Längsrippen 5 versehen.
Das durch die Kurbelwelle auf die inneren Wände des Kurbelgehäuses zerspritzte Schmieröl fliesst dem geneigten Boden entlang zur tiefsten Stelle des Kurbelgehäuses herunter, wobei es durch das durch die Kanäle 1-2-3 unter Druck durchgetriebene Kühlwasser abgekühlt wird. Die Kühlwirkung wird durch die Querrippen 4 erhöht.
Gemäss Fig. 3 sind die gleichfalls durch einen Querkanal 3'miteinander an einem Ende verbundenen Kühlkanäle l'und 2'innerlich an den Längsseitenwänden des Kurbelgehäuses angegossen, gleichfalls vorzugsweise mit inneren Querrippen 4'versehen und haben einen nach unten keilförmig sich erweiternden Querschnitt, so dass das Schmieröl an den nach innen und unten geneigten inneren Kanalwänden herunterfliesst.'
PATENT-ANSPRÜCHE :
1. Ölkühleinrichtung an Brennkraftmaschinen, bestehend aus im Boden oder den Wänden des Kurbelgehäuses vorgesehenen, vom Kühlmittel durchströmten Kanälen, dadurch gekennzeichnet, dass der Kurbelgehäuseboden in der Längsrichtung geneigt ausgebildet ist.

Oil cooling device on internal combustion engines.
The subject of the invention is an oil cooling device on internal combustion engines, especially for fire engines, which is illustrated in the drawing in two exemplary embodiments. 1 and 2 show the lower half of a crankcase provided with the cooling device according to the invention in longitudinal and cross-section; Fig. 3 shows another embodiment in cross section.
According to FIGS. 1 and 2, two separate, longitudinally extending channels 1, 2 are provided in the longitudinally ascending double bottom of the crankcase, which are connected to each other at the higher end by a transverse channel 3 and at the lower end to the cooling water circulation pipe are. The base is preferably provided with transverse ribs 4 at the top and longitudinal ribs 5 at the bottom.
The lubricating oil sprayed onto the inner walls of the crankcase by the crankshaft flows down the sloping floor to the deepest point of the crankcase, where it is cooled by the cooling water driven under pressure through channels 1-2-3. The cooling effect is increased by the transverse ribs 4.
According to FIG. 3, the cooling ducts 1 'and 2', which are also connected to one another at one end by a transverse duct 3 ', are cast on the inside of the longitudinal side walls of the crankcase, likewise preferably provided with internal transverse ribs 4' and have a cross-section that widens in a wedge-shaped manner downwards that the lubricating oil flows down the inward and downward sloping inner channel walls. '
PATENT CLAIMS:
1. Oil cooling device on internal combustion engines, consisting of channels provided in the floor or the walls of the crankcase, through which the coolant flows, characterized in that the crankcase floor is inclined in the longitudinal direction.
