发明名称 RADIATOR CAP
摘要 <p>PROBLEM TO BE SOLVED: To provide a radiator cap which is simply constructed with a smaller number of components so that a valve is opened/closed at a fixed pressure.SOLUTION: A radiator cap 20 to be mounted in a water filler 18 includes a cap body 21 for blocking the water filler 18, a pressure plate 24, a gasket 26, and pressure springs 25a, 25b. The pressure plate 24 has an upper suction hole 24a formed in the center and an outer periphery side seal part 24e formed on the outer periphery side of the lower face. The gasket 26 is installed on the lower face of the pressure plate 24 in the state of covering the upper suction hole 24a, and has a lower suction hole 26d to be communicated with the upper suction hole 24a when separated from the pressure plate 24. The pressure springs 25a, 25b press the pressure plate 24 and the gasket 26 against a thin annular part 18b, and when pushed back by a pressure, they are shrunk to form a clearance between the thin annular part 18b and the gasket 26.</p>
