  • Publication number: 20240175433
    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.

  • Patent number: 8905569
    Abstract: A lighting fixture includes a directional light source that produces a plurality of light rays. An optical module is coupled to the directional light source to focus the plurality of light rays into a beam of light rays to be output by the lighting fixture. The angular distribution of a majority of the beam relative to a vector normal to a ceiling on or near which the fixture is to be installed is in a range of 70 to 95 degrees. A blocking structure is used to block a direct view of the beam of light when the fixture is installed such that only indirect light is primarily visible from a viewer at least in or around a working plane substantially parallel to the ceiling.
