The present invention relates to a cap for a surge tank of a vehicle cooling system which can discharge the high temperature and high pressure air inside the surge tank before opening the cap to prevent a risk of burns and injuries that may occur when the cap is opened.

The engine cooling system of the vehicle is provided with a radiator, thermostat, water pump, surge tank, etc., and the thermostat is opened or closed according to the temperature of the coolant circulating the engine to circulate the coolant inside the engine or to the radiator side. .

That is, when the temperature of the cooling water is below a certain temperature, only the inside of the engine is circulated, and if the temperature is above a certain temperature, the thermostat is opened while the cooling water is introduced into the radiator, cooled, and then circulated into the engine by the water pump.

In addition, a surge tank is used to hold the cooling water during expansion and contraction of the cooling water in the cooling process of the engine and to apply a constant pressure to the cooling system.

1 is a view showing a pressure cap 10 in which the flow of cooling water and air is adjusted according to the internal pressure in the conventional surge tank 20, the pressure cap 10 in the filler neck of the surge tank 20 It is constructed by screwing.

The pressure cap 10 has a port 12 protruding from the cap body 11 to allow air to enter or exit the surge tank 20 through the port 12.

The guard 13 is fixed to the inside of the cap body 11, and holes are formed in the upper and lower ends of the guard 13 to allow air to flow.

In addition, the upper portion of the guard 13 is provided with a positive pressure valve unit, the cooling water and air in the surge tank 20 is discharged to the outside through the operation of the positive pressure spring 17 configured in the positive pressure valve unit.

That is, when the pressure inside the surge tank 20 rises above a predetermined pressure, the retainer 18 moves upward, and the positive pressure spring 17 contracts by the spring plate 15, thereby spring plate 15. A gap is formed between the gasket 16 and the guard 13 provided at the lower portion through which air can pass. Therefore, while the air inside the surge tank 20 passes through the guard 13, it passes through the gap created between the gasket 16 and the guard 13, and exits through the port 12.

In addition, the negative pressure valve unit is provided below the positive pressure valve unit, and the negative pressure spring 19 configured in the negative pressure valve unit is operated to allow external air to flow into the surge tank 20 through the port 12.
