    • A reservoir pen includes a nib, a feed bar defining an ink channel and having an ink port, and a valve for controlling flow of ink from the ink port to an underside of the nib. The valve includes a seat, a valve member, and a resilient element engaging the valve member to bias the valve member away from the ink port toward an open position. The valve member is further positioned to engage the nib to urge the valve member against the resilient element and into sealing contact with the seat. The resilient member is disposed outside of the ink channel in at least the open position.
    • 贮存器笔包括笔尖,限定墨水通道并具有墨水口的进给杆,以及用于控制墨水从墨水口流到笔尖下侧的阀。 阀包括座椅,阀构件和接合阀构件的弹性元件,以将阀构件偏离墨口朝向打开位置。 阀构件进一步定位成接合笔尖以将阀构件推靠在弹性元件上并与阀座密封接触。 弹性构件至少在打开位置设置在墨水通道的外部。
