Document Type and Number:
Japanese Patent JP2950553
Kind Code:
B2
Abstract:
A sealed type engine cooling system having a reservoir tank connected to the engine recirculating water passageway by inlet pipes connected to the upper outlet of an engine cooling water passageway and to the upper inlet of a radiator. The bottom portion of the reservoir tank is connected to the bottom of the engine cooling water passageway, for supplementing the engine cooling water, and is provided with a cap with a relief valve, to thereby discharge vapor created in the cooling water passageway under a hot soak condition. The relationship between the inner diameter of the pipes is such that the effective cross sectional area of the inlet pipe means is 1.5 to 3 times larger than the effective cross sectional area of the outlet pipe means, or the inlet pipe is arranged so that a minimum distance is obtained between the engine upper portion and the radiator, or a check valve is arranged in the outlet pipe, or the space inside the reservoir tank is partitioned into chambers, and the inlet and outlet pipes are connected to separate chambers.
