Abstract
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.
Claims20
A fluid coupling comprising:
- a male coupling defining a longitudinal axis, a seal groove, and a circumferential recess facing radially outward, the male coupling comprising:
- a frustoconical mid-body portion positioned between the seal groove and the circumferential recess, wherein a larger diameter end of the frustoconical mid-body portion is adjacent the circumferential recess and a smaller diameter end of the frustoconical mid-body portion is adjacent the seal groove;
- and
- a seal disposed in the seal groove, wherein the seal groove is smaller in diameter than the larger diameter end of the frustoconical mid-body portion;
- a female coupling defining an internal space configured to receive a portion of the male coupling, the female coupling including an end portion comprising a collet structure with radially inward-extending projections;
- and
- a collar defining a central open space, the collar engaged with the female coupling and slidable thereon between:
- (i) an unlocked end of travel position in which the collet structure is longitudinally extending outside of the central open space of the collar and (ii) a locked end of travel position in which the collet structure is within the central open space of the collar,
- wherein, while the male coupling is coupled with the female coupling and the collar is in the locked end of travel position, the radially inward-extending projections of the female coupling are releasably seated in the circumferential recess of the male coupling.
6 more elements
A fluid coupling comprising:
- a female coupling defining an internal space configured to receive a portion of a male coupling, the female coupling including:
- (i) two radial projections and (ii) an end portion comprising a collet structure with two or more jaw portions;
- and
- a collar defining a central open space and two open lateral slots through opposite sidewalls of the collar, the collar engaged with the female coupling and slidable thereon between:
- (i) an unlocked end of travel position in which the collet structure is longitudinally extending outside of the central open space of the collar and (ii) a locked end of travel position in which the collet structure is within the central open space of the collar,
- wherein each open lateral slot of the two open lateral slots has:
- (i) enlarged end portions and (ii) an open middle portion extending between the enlarged end portions,
- wherein the open middle portion of each open lateral slot of the two open lateral slots is narrower than the enlarged end portions, and
- wherein each radial projection of the two radial projections slides within and along the open middle portion of a respective lateral slot of the two open lateral slots as the collar slides along the female coupling between the unlocked end of travel position and the locked end of travel position.
6 more elements
A fluid coupling comprising:
- a first end portion;
- a second end portion;
- a mid-body portion;
- a circumferential seal groove disposed between the first end portion and the mid-body portion;
- a seal disposed in the circumferential seal groove;
- and
- a circumferential recess disposed between the second end portion and the mid-body portion,
- wherein the mid-body portion is located between the circumferential seal groove and the circumferential recess,
- wherein the mid-body portion has a first portion that is smaller in diameter than an outer diameter of the seal, and
- wherein the mid-body portion has a second portion that is larger in diameter than the outer diameter of the seal.
