摘要： PROBLEM TO BE SOLVED: To provide an integrally molded article of rubber and metal capable of improving adhesive robustness of thin film rubber layers 104, 105 integrally formed on both sides of the metal member which have lower adhesive robustness than other parts. SOLUTION: Multiple convexities and concaves 112 are formed on the joining surfaces between the thin film rubber layers 104, 105 and a metal member 110, whereby the joining surface area increases. Furthermore, biting effects are generated at the convexities and concaves 112 between the rubber layers 104, 105 and the metal member 110, whereby the adhesive robustness is improved.

摘要： PROBLEM TO BE SOLVED: To provide an accumulator 1 comprising a seal part 13 to seal pressure in a pressure chamber 10 between a bellows cap 8 and an oil port 5 for preventing the excessive reduction of pressure in the pressure chamber 10 in the accumulator 1 when pressure on the piping side to which the accumulator 1 is connected is reduced, in which a seal lip 14b of the seal part 13 is prevented from turning over by pressure. SOLUTION: The seal part 13 is formed of a cylindrical face seal provided with the seal lip 14b. The seal lip 14b is inclined toward the pressure chamber 10 to be pressed by closed fluid to tightly contact a mating member when pressure falls. A mating member slides toward the pressure chamber 10 relative to the seal lip 14b when pressure falls. COPYRIGHT: (C)2004,JPO
摘要翻译：要解决的问题：提供一种包括密封部分13的蓄压器1，以密封波纹管盖8和油口5之间的压力室10中的压力，以防止压力室10中的压力过度降低蓄能器1当连接蓄能器1的管道侧的压力减小时，密封部13的密封唇部14b被压力转过。解决方案：密封部分13由设置有密封唇缘14b的圆柱形面密封件形成。密封唇14b朝向压力室10倾斜以被封闭的流体挤压以在压力下降时紧密接触配合构件。当压力下降时，配合构件相对于密封唇缘14b向压力室10滑动。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To allow a seal lip 32 tightly adhered to a bellows cap 22 at a movable end of a bellows 20 to certainly prevent introduction of pressure in a pipe into a pressure chamber A, when the bellows 20 extends to a limit extending length by decrease of the pressure in the pipe introduced into the pressure chamber A. SOLUTION: The bellows gap 22 is disposed at the movable end of the bellows 20 separating inside the outer shell 10 the pressure lead-in chamber A and a gas chamber B. In the outer shell 10, a step surface 22b formed on the bellows cap 22 tightly adhered to the seal lip 32 prevents the seal lip 32 of a seal member 30 positioned on the outer periphery of the inner end of a pressure hole C from inverting to the inner peripheral side due to flow pressure of the fluid upon dropping of the pipe pressure and differential pressure between the pressure chamber A and the pressure hole C. A self sealing function of the seal lip 32 certainly shuts between the pressure chamber A and the pressure hole C.
