Abstract: A system for cooling plungers which operate in high pressure pumps. The system uses a plunger having a blind bore formed therein. The blind bore may receive a number of different objects, some of which are fixed to the plunger. A heat exchanger may be installed within the blind bore. The heat exchanger may have internal passages or openings which allow for the circulation of fluid within the blind bore, thus cooling the plunger. The heat exchanger may be formed of a material having a higher thermal conductivity than the material used to form the plunger. This allows the heat exchanger to cool the plunger more effectively than if the plunger were solid or filled with an empty air space. The heat exchanger may be sealed within the bore of the plunger, or exposed.

Abstract: A flangeless fluid end comprising a fluid end body releasably attached to a connect plate. The connect plate is attached to a power source using stay rods. The flow bores of the fluid end are sealed without threading a retainer nut into the walls of each bore. Instead, the flow bores are sealed by bolting a retainer to the fluid end body. Plungers to drive fluid through the fluid end body are installed within removable stuffing box sleeves. These sleeves are maintained within the plunger bores by the bolted retainers. A number of features, including the location of seals within bore walls and carbide inserts within valve structures, aid in reducing or transferring wear.

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 fluid end assembly comprising a housing having multiple conduits formed therein. A tubular sleeve is installed within one of the conduits and is configured to house a plurality of packing seals. A seal is installed within a groove formed in the walls of the housing surrounding the tubular sleeve such that the seal engages an outer surface of the tubular sleeve.

Abstract: Locking mechanisms and methods of operating the locking mechanisms are disclosed. In one example, a locking mechanism may include a main hub assembly coupleable with a deadbolt, a clutch assembly coupled to the main hub assembly, and an actuator assembly coupled to the clutch assembly. The actuator assembly may include an actuator operable to bias a carriage along a first direction to bring the clutch assembly and the main hub assembly closer to one another along a second direction, wherein the second direction is perpendicular to the first direction. The locking mechanism may further include a thumbturn assembly coupled to the clutch assembly, the thumbturn assembly comprising a thumbturn positionable on an exterior side of a door.

Abstract: A cover for vehicle interior components is provided. The cover includes a fabric sheet comprising a yarn composed of polyester microfibers. The fabric sheet has a first face and a second face wherein the first face is an A-side surface with separated and raised microfibers that provide a suede-like appearance and feel. A polyester backing layer is laminated to the fabric sheet.
