| description | A fluid end includes a fluid end block defining a chamber. A plunger is disposed in the chamber. An outlet fluid passage is formed in the fluid end block in communication with the fluid chamber. An inlet fluid passage formed in the fluid end block communicates with the fluid chamber. The inlet fluid passage includes a seat, an enlarged diameter downstream from the seat, and a neck downstream of the enlarged diameter. The neck has a lesser diameter than the enlarged diameter. An inlet valve is movably disposed in the inlet fluid passage and is sized and shaped to seal against the seat. A biasing member has a first and second end with respective first diameter and a second diameter disposed within the enlarged diameter. The second end is positioned against the neck. The second end diameter is greater than the neck. |
