    • A connector is described which includes a valve housing comprising a valve housing base and a valve cap, the valve housing defining an inlet port, and an outlet port, the valve housing further including a fluid path from the inlet port to the outlet port, the fluid path including a channel formed in an inner wall of the valve housing. A valve insert in the valve housing defines a bowl sealed by a diaphragm, such that the sealed bowl forms an inner volume in the valve housing. A valve plug operable seals the inlet port when the connector is in an unactuated state thereby closing the fluid path through the connector. Upon actuation of the connector the valve plug deforms the diaphragm into the inner volume thereby unsealing the inlet port and opening the fluid path through the connector. Because of the arrangement of the valve plug, valve insert and diaphragm, the connector has a low priming volume and has positive fluid displacement characteristics upon actuation.
    • 描述了一种连接器,其包括阀壳体,其包括阀壳体基座和阀盖,阀壳体限定入口端口和出口端口,阀壳体还包括从入口端口到出口端口的流体路径, 流体路径包括形成在阀壳体的内壁中的通道。 阀壳体中的阀插入件限定由隔膜密封的碗,使得密封的碗在阀壳体中形成内部容积。 当连接器处于未致动状态时,可操作地密封入口端口的阀塞,从而封闭通过连接器的流体路径。 在连接器致动时,阀塞将隔膜变形成内部容积,从而开启入口端口并打开通过连接器的流体路径。 由于阀塞,阀插件和隔膜的布置,连接器具有低起动容积并且在致动时具有正的流体位移特性。
