Patent number: 11933339Abstract: 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.Type: GrantFiled: August 1, 2022Date of Patent: March 19, 2024Assignee: Parker-Hannifin CorporationInventor: Nagarajan Ramaswamy

Publication number: 20240084907Abstract: 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.Type: ApplicationFiled: September 11, 2023Publication date: March 14, 2024Applicant: Parker-Hannifin CorporationInventors: Gerard G. Betz, II, Anthony F. White, David Walter Zuk
