却装置。[Scope of Claim for Utility Model Registration] A cooling water outlet 11 is opened in the front end wall of the cylinder head 7 of a water-cooled vertical multi-cylinder engine, and the cooling water in the head jacket 8 in the cylinder head 7 is routed through the cooling water outlet 11 and the hot water outlet path. In a head cooling system for a water-cooled vertical multi-cylinder engine configured to lead hot water to the hot water inlet of the radiator 2 through the cooling water outlet 11, a flow rate adjustment valve 13 is provided at the coolant outlet 11, and the flow rate adjustment valve 13 is located on the right side of the coolant outlet 11. The opening amount at the outlet portion and the opening amount at the left side exit portion are configured to be increased or decreased, and the flow rate adjustment valve 13 is configured to be operable to adjust the opening amount with the valve operation means 15, so that the left side portion of the cylinder head 7 is slightly overheated. Under the conditions, the valve operating means 15 operates the flow rate regulating valve 13 in such a direction as to increase the opening amount at the left outlet portion and decrease the opening amount at the right outlet portion, and Under conditions where the right side is slightly overheated, the valve operating means 15 operates the flow control valve 13 in such a manner that the opening amount at the left side outlet portion is reduced and the opening amount at the right side outlet portion is increased. A head cooling device for a water-cooled vertical multi-cylinder engine characterized by the following configuration.
