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 slide valve set in a fluid passage and displaceable in a direction of a longitudinal axis of the fluid passage to open or close the fluid passage, the slide valve being simplified in structure and having a plurality of seal portions. The slide valve includes a cylindrical slide valve body set coaxially with the fluid passage, the slide valve body having an outer peripheral surface, an inner peripheral surface, and at least one through-hole extending through from the outer peripheral surface to the inner peripheral surface. The slide valve further includes a seal member having an annular outer seal portion located over the outer peripheral surface of the slide valve body, an annular inner seal portion located over the inner peripheral surface of the slide valve body, and a connecting portion located in the through-hole to connect together the outer seal portion and the inner seal portion.

A female pipe coupling member includes a coupling body and a sleeve 138 disposed around a cylindrical peripheral wall portion of the coupling body. The sleeve has a locking element receiving hole extending therethrough from an inner peripheral surface to an outer peripheral surface. When the sleeve is in a locking element releasing position where the locking element receiving hole radially aligns with a locking element, the locking element is received in the locking element receiving hole to assume an unlocking position. The locking element receiving hole is configured to block the locking element from passing therethrough radially outward and thus holds the locking element in the unlocking position from outside.

A female fluid connection element (5), configured to be coupled with a male element (4). A female body (21), which has an insertion channel (27) of the male element (4); locking elements (31) movable between positions; and a maneuvering ring (71) with an inner sleeve (75) for driving the locking element (31) to their proximal position. In order to have a small bulk and to offer particularly easy and reliable locking and unlocking, the female element (5) has a return plunger (33), returning the locking elements (31) toward their distal position, and a resilient member (43), exerting a return force to bring the return plunger (33) back toward a forward position. By being moved toward its withdrawn position, the maneuvering ring (71) drives the return plunger (33) toward a rear position, such that it does not exert a return force on the locking elements (31).

The invention relates to a nozzle, which has a main valve arranged in a channel, a coupling device (30) for producing a connection between the nozzle and the connecting piece (15), and an actuating apparatus (17) for actuating the coupling device and the main valve. The actuating apparatus comprises a manual lever (11), which is movable between a closed position and an open position. The actuating apparatus is designed to convert a movement of the manual lever in a region between the closed position and the open position to a temporally offset actuation of the coupling device and of the main valve. A coupling joint (20) connected to the manual lever is connected via operative connections to the coupling device having the main valve. The operative connections for the coupling joint form a guide such that the coupling joint is caused to rotate about a first pivot axis (41) and/or to move in a first direction when the manual lever is activated in a first manual lever region, and that the coupling joint having the manual lever in a second manual lever region is caused to rotate about a second pivot axis (42) and/or to move in a second direction.

Embodiments of the present disclosure relate to a tubular connection assembly that maybe quickly connected and with improved capacity for axial loads. The tubular connection assembly may include a box end member having a first groove formed in an inner surface, a pin end member having a second groove formed in an outer surface, and a load transfer assembly comprising two or more segments. When the pin end member is inserted in the box end member and the first groove aligns with the second groove, the load transfer assembly is at least partially disposed in both the first groove and the second groove.

Quick coupling including casing defining longitudinal axis, outlet and inlet, to receive at the inlet at least part of external connector to fluidity connect external connector and outlet, shutter housed within casing to translate along longitudinal axis in opposition to opposing element, housing at least part of external connector and including retainer to lock at least part of external connector within shutter in at least one position along longitudinal axis, controller accessible from outside and including first slider housed within casing to translate along locking direction skewed relative to longitudinal axis in opposition to second opposing element, to house at least part of the shutter and including lock to lock the shutter within first slider in position along locking direction, and safety to lock shutter when subjected to pressures above predetermined threshold by fluid present within coupling, wherein the shutter locks external connector at least when safety locks shutter.

A connector assembly includes a male connector and a female connector. The male connector comprises a male connector housing, a male connector valve core, and a male connector push rod. The female connector comprises a female connector housing, a female connector valve core, and a female connector push rod. The male connector valve core has a closed position, the female connector valve core has a closed position, and the male connector is capable of being at least partially inserted into the female connector. When the male connector is inserted to a proper place in the female connector, the male connector push rod pushes the female connector valve core away from the closed position, and the female connector push rod pushes the male connector valve core away from the closed position, so that the male connector fluidly communicates with the female connector.
