Abstract

Cooling water pumped by a cooling-water pump is passed via a cooling-water supply passage, a cooling-water dispensing chamber, two upper and lower through-holes and a water jacket, a thermo-valve and discharged via a cooling-water discharge passage. When the amount of cooling water supplied from the cooling-water pump is excessive, or when the thermo-valve has been closed, a relief valve mounted in a bypass passage which connects the cooling-water supply passage and the cooling-water discharge passage is opened, thereby permitting the cooling water to be diverted. The bypass passage diverges from the cooling-water supply passage upstream of the cooling-water dispensing chamber. Therefore, even if the relief valve is opened, the flow pattern of the cooling water flowing within the cooling-water dispensing chamber is not influenced, and the flow rates of the cooling water passed through the two through-holes cannot be unbalanced.
