ABSTRACT:
A vehicle radiator cap for closing a radiator filler neck is disclosed. The radiator cap includes a central rivet for securing a crown, a bell housing, and a discoid spring and having a flared shank permitting free turning of the crown relative to the primary sealing gasket. The cap further includes a pressure spring nested within the bell housing and centered directly above an annular valve seat in the radiator filler neck. The upper turn of the spring nests in the shoulder region of the bell housing and the bottom turn biases a seal support plate against the annular valve seat. The seal support plate has an integrally formed cylinder having a lip which retains a vacuum seal in sealing relationship with the bottom surface of the seal support plate.
