Abstract
A fluid end of a reciprocating pump assembly includes a cylinder, a cover, and a valve stop. The cylinder has a fluid inlet, a fluid outlet, and an access side wall comprising an access wall inner surface that defines an access opening. The access opening provides access to an inner area of the cylinder and has an access opening axis. The cover is positioned in the access opening and forms a seal with the access wall inner surface along the access opening. The cover includes a cover axis coaxial with the access opening axis. The valve stop is positioned partially in the fluid inlet and includes a spring retainer and a column portion. The column portion includes a flange positioned between the cover and the access wall inner surface. The flange is in the shape of an arc.
