Abstract
Fluid handling couplings can be made to connect and disconnect other members of a fluid handling system. For example, this document describes fluid couplings that are convenient to couple/decouple and that provide strong resistance to inadvertent disconnection when subjected to rotation while pressurized. In some embodiments, the resistance to inadvertent disconnection is facilitated by a latch mechanism of the female coupling that includes a protrusion that becomes seated in a groove of a mated male coupling.
Claims18
A female fluid coupling, comprising:
- a coupling body defining a central longitudinal axis and an interior space for receiving a mating male coupling, an outer portion of the interior space having an oval cross-sectional shape, an inner portion of the interior space being cylindrical;
- and
- a latch mechanism coupled to the body, the latch mechanism movable, transversely relative to the central longitudinal axis, between a latched position and an unlatched position, a portion of the latch mechanism intersecting the outer portion of the interior space while the latch mechanism is in the latched position,
- wherein a center of the oval cross-sectional shape of the outer portion of the interior space is offset from the central longitudinal axis.

A fluid coupling system, comprising:
- a male coupling defining a central longitudinal axis;
- and
- a female coupling comprising:
- a coupling body defining a central longitudinal axis and an interior space for receiving an end portion of the male coupling, an outer portion of the interior space having an oval cross-sectional shape, an inner portion of the interior space being cylindrical;
- and
- a latch mechanism coupled to the body, the latch mechanism movable, transversely relative to the central longitudinal axis, between a latched position and an unlatched position, a portion of the latch mechanism intersecting the outer portion of the interior space while the latch mechanism is in the latched position,
- wherein the end portion of the male coupling can be inserted into the outer portion of the interior space while the latch mechanism is in the latched position, and
- wherein the central longitudinal axes of the male coupling and the coupling body of the female coupling are spaced apart from each other when the end portion of the male coupling is inserted into the outer portion of the interior space while the latch mechanism is in the latched position.
