Abstract: A valve stop retainer device (220) that is adapted to interface with a cross-bore fluid communication chamber (262) of a reciprocating pump (250) includes a spring retainer plate (221) and a plurality of retainer lobes (223) extending substantially away from a first side of the spring retainer plate (221). Each of the plurality of retainer lobes (223) includes an upper portion (223u) having an outer surface (223s). A shape of each of the outer surfaces (223s) and a shape of an inside surface (261) of the cross-bore fluid communication chamber (262) interfacing with the valve stop retainer device (220) substantially conform to a shape of at least a portion of a surface of revolution. The valve stop retainer device (220) is adapted to be retained inside of the cross-bore fluid communication chamber (262) by the shape of the inside surface (261).
