Abstract (en)

[origin: EP0159373A1] A frangible pressure relief disc assembly is disclosed which is adapted to fit into a positive displacement pump on the suction side of each cylinder. The disc assembly (1) provides a pressure relief when the fluid passing through the pump encounters a closed valve or other obstruction in the line. The disc assembly (1) comprises: (a) a support member (2) having a first side and second side which is penetrated by a passage (5) (e.g., a bore) providing fluid communication from the first side to the second side, and (b) a pressure frangible disc (3) fixedly attached to the support member (2) and positioned to form a fluid-tight seal covering the passage.
