Abstract

A high pressure diaphragm pump has a diaphragm 2 which carries a valve poppet 7 on its upper surface. The valve poppet 7 fits into a flared portion 6 of a passage 4 for hydraulic fluid. When the diaphragm 2 restores to the position shown in Figure 1, the valve poppet 7 closes the passage 4 and prevents the diaphragm being punched back into the passage by excessive fluid pressure on the opposite side of the diaphragm. The diaphragm is made with flat edges 10, 11, 12 so that it can easily be mounted in a housing by means of three easily formed components 13, 14, 15. A small axial compression between components 14 and 15 is all that is necessary to keep the diaphragm in place during operation. [EP0012584A1]
