Abstract
A non-negative pressure radiator cap is provided and includes a pressure valve having a pressure member, disposed inside a body while having an aperture formed therein. The pressure member is pressed based on an increase in pressure of coolant to move coolant toward a reservoir tank. Additionally, a vacuum valve that includes a head part and a neck part moves vertically based on the pressure of the coolant to open or close the aperture. The neck part passes through the aperture from bottom to top. A sealing member is disposed between the pressure valve and the vacuum valve and has an insertion aperture that is formed at a position corresponding to the aperture of the pressure valve. A retainer is further inserted into the aperture and the insertion hole and a guide directs the vacuum valve to move vertically when the vacuum valve is opened or closed.
