Claims

[Claims for Utility Model Registration] A hot water outlet 19b for cooling water is provided in the upper part of the water jacket 19 of the horizontal engine 6, a cold water inlet 19a is provided in a lower part thereof, a hot water inlet 10a is provided in the upper part of the radiator 10, and a hot water inlet 10a is provided in the lower part of the water jacket 19 of the horizontal engine 6. Open the cold water outlet 10b and open the hot water outlet 19b of the water jacket 19.
is communicated with the hot water inlet 10a of the radiator 10 via a flexible hot water pipe 46, and the cold water outlet 10b of the radiator 10 is communicated with the cold water inlet 19a of the water jacket 19 via a cold water pipe 47, so that the cooling water is Heat is absorbed within the jacket 19 and the cylinder 14
A water-cooled type horizontal engine configured such that high-temperature water cools the cylinder head 17, passes through a hot water pipe 46, radiates heat through a radiator 10, becomes low-temperature water, and circulates through a cold water pipe 47 to a water jacket 19. In the cooling system, the radiator 10 is arranged in the lateral outer space A of the cylinder head 17 located on the lateral side of the horizontal engine 6, and the hot water inlet 10a of the radiator 10 is located close to the hot water outlet 19b of the water jacket 19. At the same time, connect the cold water outlet 10b of the radiator 10 to the cold water inlet 19 of the water jacket 19.
a, and connect the cold water outlet 10b of the radiator 10 to the cold water pipe 47.
・The water pump 50 is connected to the cold water inlet 19a of the water jacket 19 via the discharge pipe 50b and the pipe connection flange 55, and the low temperature cooling water cooled by the radiator 10 is pumped from the radiator 10 to the water jacket by the water pump 50. The pipe connection flange 55 is removably fixed to the rear surface 17a of the cylinder head 17 with a fixture 56, the pump support frame 57 is fixedly extended from the pipe connection flange 55, and the water is supplied to the pump support frame 57 under pressure. A horizontal engine that supports a pump 50 and is characterized in that a pump shaft 60 that projects rearward from the water pump 50 is interlocked and connected to a rotating shaft 29 that projects rearward from the crankcase 13a via a wrap transmission device D. water-cooled chiller.
