发明名称 Improvement in a diaphragm failure detection device for a double diaphragm pump.
摘要 <p>The improved diaphragm failure detection device for a hydraulically operated pump comprising two diaphragms (2,7) tightly gripped on their periphery on a fixed structure comprising an annular part (8) inserted between the two diaphragms (2,7) is such that, as the internal space between the two diaphragms connects with at least one duct (10) linked to an external detector (11) by way of the intermediate annular part, the duct (10) comprises a branch (13) connecting its volume with the atmosphere by way of a capillary pipe (14). &lt;IMAGE&gt;</p>
