Abstract: A fluid end for use with a power end. The fluid end comprises a plurality of fluid end sections positioned adjacent one another. Each section includes a single horizontally positioned bore. A plunger is installed within the bore and includes a fluid passageway. Low-pressure fluid enters the bore through the plunger and high-pressure fluid exits the fluid end through an outlet valve installed within the bore. The intake of low-pressure fluid within the fluid end section is regulated by an inlet valve installed within the plunger. Low-pressure fluid enters the plunger through an inlet component attached to both the plunger and an inlet manifold.

Abstract: A valve having a nose joined to a strike face. The strike face is configured to engage a tapered sealing surface formed on a component having a central fluid bore. The valve and component are configured to be installed within a fluid end. When the strike face of the valve engages the tapered sealing surface of the component, the nose is installed within the central fluid bore of the component. In operation, fluid is restricted from flowing between the strike face and the tapered sealing surface until fluid pressure has pushed the nose entirely out of the central fluid bore, thereby increasing the cross-sectional area available for fluid flow.
