This coupling (R) comprises a male element (A) with a stepped outer groove (20), a female element (B) with locking balls (7), a locking ring (9) provided with a front inner notch and a rear inner notch axially separated by an inner rim, a spring that pushes the locking ring (9) back into the forward position, and a valve movable in the female element (B) and pushed by a spring (14) back to the closed position. The male element (A) comprises a valve movable in an inner channel (200) of the male element (A) and a spring (48) that pushes the valve of the male element (A) back toward a closed position of the inner channel (200).

A catheter connector assembly which may be included with a corporeal drainage system, and a method of draining fluid from a bodily cavity. The catheter connector assembly may include a catheter connector and a drainage line connector. The catheter connector may include a connector body with a coupling feature, a deformable sealing element, and a retaining member. The drainage line connector may include a drainage line body first and second hinge clips, and an actuator. The actuator is designed to deform the deformable sealing element when the drainage line connector is coupled to the catheter connector.

A coupling and method are provided that include a coupler and nipple. The nipple has a valve in a normally-closed position and an outer peripheral surface with a plurality of spaced-apart, close-ended cam paths. The coupler has a valve in a normally-closed position and includes a set of latching balls for engagement with the cam paths to secure the coupler to the nipple. The coupler further includes a sleeve mounted thereon and movable between forward and retracted positions. In the forward position, the latching balls are forced into an inward position that prevents release of the latching balls from the cam paths, and in the retracted position, the latching balls are permitted to extend to an outward position enabling initial engagement with or disengagement from the cam paths. The coupler also includes a set of locking balls that prevents movement of the sleeve to the retracted position.

A coupling for the connection of pipelines and includes a coupling element and a complementary coupling element that can fit into one another wherein the coupling element includes a first body, a locking ring mounted around the first body, the first body being secured in translation with the locking ring, and wherein the locking ring includes a slot to receive a radially protruding part of the complementary element, a locking notch in which the protruding part can be axially locked and wherein a lever is radially rotatable in the slot and an elastic element urges the lever toward a locking position in which the lever locks the protruding part in the notch. The coupling also has a single sealing gasket mounted on an outer surface of the first body to cooperate with the complementary element.

An embodiment includes a rapid-connect coupler including a coupler body configured to convey a fluid; a coupling head at a first end of and communicating with the coupler body, the coupling head configured to transition between a coupled configuration and a de-coupled configuration. The coupler may further include a stop apparatus configured to allow the coupling head to transition from the de-coupled configuration to the coupled configuration without obstruction, and the stop apparatus may be configured to provide a hard-stop as the coupling head transitions from the coupled configuration to the de-coupled configuration.

The present invention relates to safety mechanisms for high-pressure fluid delivery systems. Particularly, the invention relates to a breakaway device which prevents uncontrolled whipping of the conduit ends upon a rupture. A heat dissipating coupling, permitting operation of the conduit system at desired temperatures, is also included, as is a breakaway device provided with such a heat dissipation feature.

A conduit coupling can have a male portion and a female portion, with each portion having an internal biasing member. When the male portion is disconnected from the female portion, the internal biasing member in the male portion can cause a seal on a moveable plug to be biased against a lip of a stationary wall member to seal liquid from leaking out of the male portion. Also, the internal biasing member in the female portion can cause a lip of a moveable wall member to be biased against a seal that is connected to a stationary plug. Both the stationary plug and moveable plug can be connected to retaining portions by strips that are disposed away from an axis of the conduit coupling.

The present disclosure relate to coupling components including valve structures and methods for forming the valve structures. The method includes attaching together a male valve piece (52) and a female valve piece (54) to form a valve structure that extends along a longitudinal axis. The method includes inserting the male (52) and female (54) valve pieces axially together. The method also includes using a swaging tool (200) to inelastically deform at least one of the male and female valve pieces from an insertion configuration to a locking configuration in which relative axial movement between the male and female valve pieces is prevented.

The present disclosure relates to a low-spill coupling assembly including a female coupling device and a male coupling device.
