Abstract
A pressure cap for a cooling system of a vehicle may include a reservoir fill port which is mounted at an upper portion of a reservoir in which cooling water is stored in a cooling system of the vehicle; an external cap for closing an upper end portion of the reservoir fill port; a pressure valve disposed in the reservoir fill port to allow the inside and the outside of the reservoir fill portion to fluidically-communicate with each other; a valve seal provided to allow the air to flow from the outside into the internal to the cooling system by being deformed when pressure in the internal to the cooling system is lower than a predetermined pressure; and a positive pressure spring elastically supporting the pressure valve such that the pressure valve closes the internal to the reservoir fill port.
