Abstract
A cooling structure for cooling a liquid-cooled engine has engine cooling passages defined in portions of the engine for circulating a cooling medium therethrough. The cooling structure further includes a rotatable assembly having a rotatable element located outside of the engine, and a radiation passage system of a prescribed length disposed in the rotatable element for rotation therewith and connected to the engine cooling passages.
Claims16
A cooling structure for cooling a liquid-cooled engine having cooling passages therein for circulation of a liquid cooling medium therethrough, said cooling structure comprising:
- a rotatable assembly located outside of the engine and driven by the engine, said assembly comprising a shaft extending through at least a portion of the engine and an auxiliary rotatable element mounted on a portion of said shaft which projects out of the engine;
- said auxiliary element comprising a disc element having at least first and second axially divided portions, a portion thereof comprising a sinuous passage for lowering the temperature of a liquid cooling medium;
- and
- means for connecting a liquid medium of said engine to said auxiliary element for circulation through said sinuous passage.
A cooling structure for cooling a liquid-cooled engine having cooling passages therein for circulation of a liquid cooling medium therethrough, said cooling structure comprising:
- an engine flywheel connected to a crankshaft of the engine to be driven thereby, said flywheel including liquid cooling apparatus comprising a sinuous passage for lowering the temperature of a liquid medium circulated therethrough;
- pump means driven by the engine for circulating engine oil lubricant as a liquid cooling medium;
- passageway means formed in said crankshaft at a portion thereof passing through a crankshaft journal;
- and
- means for connecting said pump means to pump engine oil lubricant through said passageway means, said liquid cooling apparatus, and said engine cooling passages for cooling said engine, said crankshaft journal being simultaneously lubricated by said oil passing therethrough.
