ABSTRACT:
An oil pump arrangement for the pressure oil supply for internal combustion engines, especially a gear oil pump, which comprises impeller gears housed in a pump housing. The gears are driven by the internal combustion engine and the pump housing is connected with a suction pipe and a pressure pipe. The pump housing is arranged in an unmachined recess provided at the side of the timing gears in the crankcase. The pump housing is open on the side of the driving means for the impeller gears and is flanged to the timing gear case of the internal combustion engine. The timing gear case forms the closure of the pump housing and the recess, and at least the driving means for the impeller gears is supported in the timing gear case.
