  • Patent number: 11958007
    Abstract: A filter element includes a frame having an outlet panel and two side panels defining a U-shape. A U-shaped media anchor channel extends along the distal side edge of each panel. Each media anchor channel can have a snap-tab or other locking feature. The element encloses a pleated panel filter media pack having a side edge along each side of the pack. Each side edge of the media pack is located in a media anchor channel, and a bead of adhesive is applied along the channel. A pair of seal bars, each having a u-shape and a snap-tab or other feature that cooperates with the u-shape and the snap-tab of each media anchor channel, is pressed into each channel. Each seal bar mechanically retains a respective media side edge in the channel and together with the adhesive, provides a consistent, robust seal between the media and the frame.

  • Patent number: 11933339
    Abstract: A fitting assembly includes an indicator assembly that provides a visual indication of torque value to verify when the desired operational torque value is achieved. The fitting assembly includes a nut, and a visual indicator assembly positioned on the nut which has a plurality of visual indicators that provide a visual indication of a torque level being applied. A sleeve is attached to the nut and includes a window through which a portion of the visual indicators is visible based on the torque level being applied. A resilient member couples the sleeve to the nut. As the nut is rotated to apply torque to the nut, the resilient member biases the sleeve in a fixed position and the nut rotates relative to the sleeve, whereby the visual indicator assembly rotates relative to the sleeve to alter which portion of the visual indicator assembly is visible through the window to provide a visual indication of when the operational torque level is being applied.

  • Publication number: 20240084907
    Abstract: An enhanced low noise relief valve renders the anodizing processing irrelevant to the low leakage nature of the valve member based on the tolerance between the tube portion of the valve member and the inlet bore of the machined housing. This is accomplished by providing an additional valve stem holder that acts as a stem holder through which at least part of the tube portion of the valve member extends, with the stem holder instead of the valve member tube being located adjacent to the bore of the machined housing. The stem holder does not need to be subject to the anodizing process, and therefore a tight tolerance between the valve member and stem holder provides adequate leakage control, and the anodizing process applied to the machined housing otherwise is separated from the location where leakage tolerance is critical.

  • Patent number: 11925891
    Abstract: A filter media and methods are provided. The media is stretchable and exhibits a high degree of elongation which thereby extends its surface area during pleating. By extending surface area of media during pleating, the initial differential pressure is lowered as the area of media is stretched while keeping the same efficiency range with a compressed thickness of media on the affected area.

  • Publication number: 20240068567
    Abstract: A metal seal for a flat face fluid coupling includes an annular seal body and a retainer having a fixed end fixed to the seal body, a free end spaced from the seal body, and an intermediate portion extending between the free end and the fixed end. The retainer is configured to engage a wall of the fluid coupling with a retaining force for securing the seal to the fluid coupling. The seal body has opposite first and second flat annular sealing surfaces, and a radially outer annular angled portion that is inclined relative to the annular sealing surface. The angled portion is configured to enhance stiffness around a circumference of the seal body, and is configured to engage a face of the fluid coupling to generate a moment of force about the retainer for enhancing the retaining force acting against the wall of the fluid coupling.

  • Publication number: 20240003423
    Abstract: A shaft seal assembly for sealing a moving shaft of a fluid consumer includes a seal case movable relative to a mating surface of the shaft, a biasing force that biases the seal case towards the mating surface, and a seal at least partially disposed in the seal case. In a dynamic condition, when fluid pressure against the seal case is equal to or greater than a threshold pressure, the seal case sealingly separates from the mating surface, and the seal is forced into sealing engagement against the mating surface of the shaft to form a dynamic seal. In a static condition, when fluid pressure exerted against the seal case is less than the threshold pressure, the seal is sealingly engaged against the mating surface to form a static seal, and the seal case is sealingly engaged against the mating surface of the shaft to form an additional static seal.
