ENGINE COOLING DEVICE

An engine cooling device comprises an oil jacket (16) surrounding a cylinder portion of an engine, an oil gallery (2) supplying high-pressure oil to various parts of the engine, and an oil pressure regulator (24, 46) disposed between the oil jacket (16) and the oil gallery (20) to reduce the pressur...

Beschreibung
Zusammenfassung:	An engine cooling device comprises an oil jacket (16) surrounding a cylinder portion of an engine, an oil gallery (2) supplying high-pressure oil to various parts of the engine, and an oil pressure regulator (24, 46) disposed between the oil jacket (16) and the oil gallery (20) to reduce the pressure of the high-pressure oil supplied from the oil gallery and to supply the oil at a reduced pressure to the oil jacket. Thus, the required mechanical strength of the oil jacket can be decreased to decrease the weight of the engine cylinder block (1).
