    Abstract: In one example in accordance with the present disclosure, an interconnect on a print liquid supply is described. The interconnect includes a liquid interface to establish a liquid path between the print liquid supply and an ejection device in which the print liquid supply is installed. The interconnect also includes an electrical interface to establish a data transmission path between the print liquid supply and the ejection device. The interconnect also includes an external surface having a dampening element disposed thereon.

    Abstract: A fluid dispensing apparatus including a fluid ejector including a fluid reservoir having fluid, and configured to eject the fluid, a vacuum pump configured to create negative pressure in an activation mode and to create approximately no pressure in a deactivation mode, a meniscus pressure regulator configured to regulate the negative pressure received from the vacuum pump, a leaking member configured to reduce the negative pressure received from the vacuum pump towards or equal to atmospheric pressure in response to the vacuum pump being placed in the deactivation mode, and a back pressure regulator having a pressure reference port to receive the reduced negative pressure from the leaking member and the regulated negative pressure from the meniscus pressure regulator, the back pressure regulator configured to maintain a non-retraction negative pressure value to position a fluid meniscus in a non-retracted state and a retraction negative pressure value to position the fluid meniscus in a retracted state.

    Abstract translation: 一种流体分配装置，包括流体喷射器，其包括具有流体的流体储存器，并且被配置为喷射流体;真空泵，构造成在致动模式下产生负压并且在去激活模式中产生大致无压力，配置在弯液面压力调节器 以调节从真空泵接收到的负压，泄漏构件被配置成响应于真空泵被置于失活模式而将从真空泵接收的负压减小到等于大气压;以及背压调节器，其具有 接收来自泄漏构件的减小的负压的压力参考端口和来自弯液面压力调节器的调节负压，后压力调节器被配置为保持非回缩负压值以将流体弯月面定位在非缩回状态 和回缩负压值以将液体弯液面定位在其中 缩回状态。
