This disclosure relates to an irrigation system pipe joint or span coupling, which can connect a span of an irrigation system to another structure. In examples, the joint can include various components that attach an end of a first pipe or joint to an end of a second pipe or joint. For example, the end of the first joint can include a receiver plate, which can include a recess with a bushing. In addition, the end of the second joint can include a post, hook, or other elongated member that, in order to connect the first joint to the second joint, is insertable into the bushing.

A coupling member for a blind mate fluid coupling includes a housing and a valve body that is self-centering and alignable relative to the housing. The valve body may include at least two radial shoulder portions or abutments that are configured to engage at least two corresponding radial abutments of the housing to improve self-centering when in a decoupled state. A biasing member may urge the valve body abutments against the corresponding housing abutments to compensate for misalignment and/or provide self-centering in both a decoupled and mated state.

A fluid fitting of an embodiment mainly includes a socket part, a spherical valve inserted in the socket part, and a plug part configured to be inserted at a tip portion thereof into the spherical valve. Moreover, the plug part is fixed in the direction of turn by engaging an expanded-diameter portion of the plug part with a recess of the socket part. Thus, the plug part is prevented from being detached from the socket part while the fluid fitting is in use.

An exemplary bulkhead connector assembly may include a housing that has an inner diameter surface, a first opening and a second opening. The assembly may further have a retainer attached to the housing and one or more feet extending radially inward from the inner diameter surface of the housing. The assembly can also include a collar that has a portion received within the first opening or the second opening. The collar may have an outer surface that cooperates with the feet of the retainer to hold a conduit within the housing.

Various embodiments include an adapter between two connectors and a coaxial coupling or a coaxial nipple. The two connectors are any combination of a separate coupling and a separate nipple. The adapter may include: a body with two cylindrical openings; a first element that fits in the first opening with connections for a first of the two connectors and the coaxial coupling or nipple; and a second element that fits in the second cylindrical opening, and a third connection for the other connector. The first element slides and rotates in the body and has a central axis eccentric to a central axis of the cylindrical first element part. The second element slides and rotates in the body. The central axis of the third connection is eccentric to a central axis of the cylindrical second element part.

A centering interface is arranged between a tubular element mounted in a device, specifically a receiving tube or quiver, for a suction rod of a dialysis machine, and a movable element preferably guided pivotally about an axis, specifically a front plate of the dialysis machine. Centering surfaces are mated between the tubular element mounted in the device and the movable element. When a preferably sealed joint of the interface is manufactured, the tubular element mounted in the device can be moved in the axial direction against the force of a biasing spring during the movement of the movable element and the accompanying approach of the centering surfaces, while its guiding support allows a movement that permits the centering surfaces to be brought into the joining position with centering surface axes aligned with each other free of constraint forces.

The present invention relates to a fluidic connection device, comprising a flange, and a nozzle through which passes a distal internal channel, and which is configured so as to be fluidically coupled to a complementary connection device. The nozzle, mounted in the flange with the possibility of tilting relative to the flange, comprises a rear end, and a front end. The invention also includes a rod comprising an intermediate internal channel; a front end, mounted in sealed cooperation with the rear end of the nozzle with the possibility of tilting of the rod relative to the nozzle and relative to the flange, for fluidic communication between the distal internal channel of the nozzle and the intermediate internal channel of the rod; and a rear end for fluidic communication between a proximal internal conduit and the intermediate internal channel.
