SPRAY COOLED OIL SYSTEM FOR AN INTERNAL COMBUSTION ENGINE |
| 摘要 |
An engine includes a crankcase defining a crankcase space, a first shaft disposed at least partially within the crankcase and supported for rotation by the crankcase, and an oil pump coupled to the first shaft and operable to draw low pressure oil from the crankcase and discharge a flow of high pressure oil. A pressure relief path is positioned to selectively receive a portion of the flow of high pressure oil and a pressure relief assembly is coupled to the pressure relief path and is arranged to spray the portion of the high pressure flow that passes through the pressure relief passage against an interior surface of the crankcase. |
