Publication number: 20240133500Abstract: Fluid couplings described herein are designed to prevent spillage of fluid when connecting and disconnecting the couplings. In some embodiments, the fluid couplings described herein include internal valve components. In some example embodiments, the internal valve components include two springs that are arranged to exert their spring forces in parallel with each other to bias a valve component to a normally closed position. Some embodiments include a single spring. In particular embodiments, components of the fluid couplings and fluid flow paths of the fluid couplings have oblong transverse cross-sectional shapes.Type: ApplicationFiled: October 18, 2022Publication date: April 25, 2024Inventor: Elizabeth J. Langer

Publication number: 20230184359Abstract: This document describes fluid coupling devices for fluid handling systems. For example, some embodiments described in this document relate to fluid coupling devices that snap together, and are then secured to each other using a collar and collet mechanism. Some fluid coupling devices described herein are well suited for use in systems that provide fluid cooling for heat generating devices such as computer hardware. The fluid coupling devices described herein are also suitable for many other uses.Type: ApplicationFiled: January 27, 2023Publication date: June 15, 2023Inventors: Yogesh Mohan Bhat, Elizabeth J. Langer, Grant A. Wilhelm

Patent number: 11612731Abstract: Quick disconnect fluid coupling devices described herein. The fluid couplings are configured for use in fluid systems for the purpose of providing a low-spill quick disconnect coupling. The fluid couplings include portions that are pivotable in relation to each other to open and close a fluid pathway through the fluid couplings. Particular embodiments of these fluid coupling can be configured to improve medical fluid handling equipment because the fluid coupling devices can be connected and disconnected (e.g., multiple times) while minimizing fluid spillage.Type: GrantFiled: September 28, 2018Date of Patent: March 28, 2023Assignee: Colder Products CompanyInventors: Elizabeth J. Langer, Randall S. Williams, Gary J. Harris

Patent number: 11415251Abstract: A female coupling device includes: a main body, and a clip member coupled to the main body, the clip member having a plurality of arms extending perpendicularly therefrom, with the plurality of arms forming at least one pair of arms, with the pair of arms including a first distance therebetween and a second distance therebetween, with the first distance being sized to engage a clip groove of a mating male coupling device, and with the second distance being sized to disengage the mating male coupling device. In a locked position, the pair of arms is positioned so that the first distance is adjacent to the mating male coupling device. In an unlocked position, the pair of arms is positioned so that the second distance is adjacent to the mating male coupling device.Type: GrantFiled: November 5, 2020Date of Patent: August 16, 2022Assignee: Colder Products CompanyInventors: Robert Keith Johnson, Grant A.
