摘要：
A mechanism for reducing pressure pulsation includes a pair of metal dampers formed by joining two disk-shaped metal diaphragms over an entire circumference and forming a hermetically sealed space inside a joined portion, with gas being sealed in the aforementioned hermetically sealed space of the damper, has a pair of pressing members which give pressing forces to both outer surfaces of the aforementioned metal dampers at a position at an inner diameter side from the joined portion, and is unitized with the pair of pressing members being connected in a state in which they sandwich the metal damper.
摘要（中）：
用于减小压力脉动的机构包括一对金属阻尼器，其通过在两个圆周上连接两个盘形金属隔膜并在接合部分内形成气密密封空间而形成，气体密封在阻尼器的上述密封空间中， 具有一对按压构件，其在与接合部的内径侧的位置处对上述金属阻尼器的两个外表面施加按压力，并且将该一对按压构件与它们夹着的状态连接 金属阻尼器。
