Fluid coupling assembly

TL;DR: In this paper, a polarized manifold connection device for connecting multiple conduits from a compression sleeve having inflatable chambers to multiple tubing from a source of pressurized fluid is disclosed, which consists of a male connector half and a female connector half each having a similar visually perceptible asymmetrical configuration of their respective housings defined by rigid elements which resist deformation of the housings.

TL;DR: In this paper, a coupler assembly for supplying different fluids has a base member adapted to supply one fluid through a first socket member and a second different fluid through another spaced socket member.

TL;DR: A quick-connect fluid coupling for fluid conduits includes first and second identical interfitting bodies (10, 10'). Each of said bodies includes barrel portions (14) and sleeve portions (16). The sleeve portions include barrel accepting recesses (34). Each body portion also has a forward projection (48) including an angled ramp (50) and a step (52) and an opposed U-shaped latch (54).

TL;DR: A quick connect fluid coupling as mentioned in this paper is a fluid coupling having a minimum number of parts, which can be quickly assembled and disassembled, and which provides a good seal in an environment which is subject to vibrations and to relative motion between a fluid line and a port defining structure.
