System for testing valves

A chamber assembly for testing a valve is disclosed and includes a proximal chamber portion that defines a proximal interior space, a distal chamber portion that defines a distal interior space that is confluent with the proximal interior space, and a valve holder that is disposed between the proximal interior space and the distal interior space. The valve holder is configured to receive the valve in a bore of the valve holder. The valve holder includes one or more return flow orifices such that the proximal interior space is in fluid communication with the distal interior space via the one or more return flow orifices. 本发明公开了种用于测试瓣膜的室组件，所述室组件包括限定近侧内部空间的近侧室部分、限定与所述近侧内部空间汇合的远侧内部空间的远侧室部分、以及设置在所述近侧内部空间与所述远侧内部空间之间的瓣膜支架。所述瓣膜支架被构造为在所述瓣膜支架的孔中接纳所述瓣膜。所述瓣膜支架包括个或多个回流孔口，使得所述近侧内部空间经由所述个或多个回流孔口而与所述远侧内部空间流体连通。
