用于喷射供给装置的冲击腔室
摘要：
本发明提供了一种喷射排出组件(400)，它包括储存器(30)和冲击腔室组件(10)。该冲击腔室组件包括：腔室部分(13)，该腔室部分限定了具有总体轴线的空腔；活塞(20)，该活塞可沿总体轴线滑动地容纳在空腔内，并包括流体进口，因此限定了具有出口喷嘴(16)的可变容积冲击腔室。流体进口包括导管(22)，该导管用于在它和储存器出口之间的相对运动过程中与储存器出口可滑动地啮合。腔室部分相对于储存器静止布置，因此，通过流体进口从储存器向冲击腔室排出一定量药物使得活塞朝着储存器运动，从而冲击腔室接收该排出量的药物。
摘要（英）：

The invention provides a jet expelling assembly (400) comprising a reservoir (30) and an impulse chamber assembly (10). The impulse chamber assembly comprises a chamber portion (13) defining a cavity having a general axis, a piston (20) received in the cavity along the general axis and comprising a fluid inlet, thereby defining a variable-volume impulse chamber with an outlet nozzle (16). The inlet comprises a conduit (22) adapted to slidably engage a reservoir outlet during relative movement therebetween. The chamber portion is arranged stationary relative to the reservoir, whereby expelling an amount of drug from the reservoir to the impulse chamber via the inlet causes the piston to move towards the reservoir, the impulse chamber thereby receiving the expelled amount of drug.
