摘要： PROBLEM TO BE SOLVED: To provide a simple sealing structure capable of preventing the leakage of a gas of wide pressure fluctuation and high pressure. SOLUTION: A resin sub-seal member 11 having a recessed groove 16 is mounted at a high-pressure side of a rubber main seal member 10, to prevent the transmission of pressure fluctuation to the main seal member 10, when the pressure of gas at high-pressure side is fluctuated. A fluctuation reducing space 13 is formed between the seal members 10, 11, so that the pressure fluctuation can be reduced by the fluctuation releasing space 13 even when the gas leakage at the sub-seal member 11 and the delay in response of the sub-seal member 11 to the pressure fluctuation occur. Whereby the sudden change of the pressure of gas around the main-seal member 10 can be prevented, the blister phenomenon can be prevented, and high sealability can be achieved. The simple structure can be realized as only the seal members 10, 11 and the fluctuation reducing space 13 are mounted. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a structurally simple sealing structure preventing the leakage of gas whose pressure variation becomes large and high pressure.
SOLUTION: A resin sub-seal member 11 having a recessed groove 16 is arranged on the high pressure side of a rubber main seal member 10, and when the pressure of high pressure side gas varies, this pressure variation is prevented from being transmitted to the main seal member 10. A variation relieving space 13 is also formed between the respective seal members 10 and 11, and even if a response delay of the sub-seal member 11 to the leakage of the gas and the pressure variation in the sub-seal member 11 is caused, the pressure variation can be relieved by the variation relieving space 13. Thus, a sudden change in the pressure of the gas around the main seal member 10 is prevented, and the occurrence of a blister phenomenon is prevented, and high sealability is attained. The respective seal members 10 and 11 and the variation relieving space 13 are only preferably arranged, and can be achieved in a simple constitution.
