COMMON DRAINAGE SYSTEM AND APPARATUS FOR ENGINE OIL SUMP AND FOR OIL FILTER OF ENGINE

摘要

A drainage system and apparatus for use with the lubricating system of an engine which provides a common drain for the engine crankcase sump and for the engine lubricating oil by-pass filter in a manner which insures against mixing of the contaminants in the filter with the engine oil in the sump. The drainage system is particularly useful in connection with the engine lubrication system of vehicles such as road construction vehicles, agricultural vehicles, tractors, or the like. The common drainage manifold used in the aforementioned drainage system is preferably mounted on the crankcase guard or "bellypan" usually provided with such vehicles and at a location where the engine crankcase sump and the lubricating oil by-pass filter may be drained simultaneously with ease and simplicity, and with all oil and sludge draining to the outside of the vehicle.
