Male and female fittings are configured to mate to form a valved connector system. Some embodiments of the female fitting include movable poppet configured to sealingly engage a flared projection within the female fitting. Some embodiments of the male fitting include a male mating aperture, and a movable plug configured to sealingly engage the male mating aperture. When the female fitting is mated with a male fitting, the male fitting forces the poppet to disengage from the flared projection, and the flared projection forces the plug to recede into the male fitting, to open a fluid path through the valved connector system.

An anti-spray structure for a connection of an air nozzle of a tire of a vehicle and a connection hose of an air compressor, and the air compressor contains: a box, a sealant supply can, and a connection hose. The box accommodates the air compressor. The sealant supply can includes an open segment and a supply tube. The connection hose includes a first segment and a second segment. The second segment has an anti-spray connector including a fitting sleeve. The fitting sleeve has a threaded orifice, a through orifice, and a projected shoulder. A cylindrical base includes a cylindrical room, a stepped coupling segment, a conduit, and a first stepped portion. A first spring is received into the cylindrical room. A valve bolt includes a post, a connecting disc, spaced slots, and a first seal ring. A lock element includes a hollow cavity, a hexagonal tab, and a tilted extension.

Methods and apparatus are disclosed for a coupling nozzle for cryogenic fluid. An example nozzle comprises a flow body defining a conduit, an inlet, and an outlet. A pneumatic cylinder is configured to slide between an extended position and a contracted position. The pneumatic cylinder is coupled to and configured to actuate the flow body. A locking mechanism is configured to secure the coupling nozzle to a receptacle. A flow control assembly comprises a valve seat fixed to the flow body adjacent the inlet and a plug configured to slide. When the locking mechanism is locked and the pneumatic cylinder actuates to the extended position, the valve seat is to disengage from the plug to open the flow control assembly. When the locking mechanism is locked and the pneumatic cylinder actuates to the contracted position, the valve seat is to engage the plug to close the flow control assembly.

Various aspects of the invention described herein relate to a removable connector assembly, and methods of use and manufacture thereof. More particularly, certain embodiments relate to apparatus and methods to provide a connection to a spout disposed upon a container, such as upon a bag holding fluid. Embodiments of connector assemblies comprise an elongated outer housing, an inner housing, and a slider assembly for moving the outer surface of the sleeve member over the inner surface of the outer housing wall in a lengthwise motion to position the spout connector upon the spout and secure the spout connector in said position.

A coupling element for a pressure medium line hydraulic coupling includes a housing, a sleeve inner body, a pressure casing and a valve tappet. The housing has a flow channel for pressure medium. At least the inner body, the casing and the tappet can be shifted, during coupling, from a starting position, along the coupling axis in a first direction into a coupling position where a block secures a coupling plug to the coupling element. They can be shifted from the coupling position in a second direction opposite the first direction, along the coupling axis into a stop position blocking further movement of the casing in the second direction. The inner body and the tappet are moveable further in the second direction into an open position where a flow cross-section is released between the casing and the tappet and a lock acts on the inner body and the tappet.

A coupler for a fluid transport system comprising a handle being continuous around the coupler, the coupler having a first end and a second end, the handle having a non-constant radius with respect to the central longitudinal axis of the coupler, the handle comprising a plurality of regions being proximal the first end of the coupler, and a plurality of regions being distal the first end of the coupler.

A device including a first connector and a second connector. The first connector and the second connector include a stationary body defining a fluid circulation conduit opening up into a connection opening, and a valve that is movable in relation to the stationary body, between a closing position in which the valve closes the connection opening, and a release position in which the valve opens up a passage through the connection opening. The device also comprises a first locking arrangement designed to lock the movable valve of the first connector to the stationary body of the second connector and second locking arrangement designed to lock the stationary body of the first connector to the movable valve of the second connector.

A dry disconnect device including a first portion defining an outlet and an outlet portion of a fluid pathway and a female valve disposed within the first portion having an extended position, including the female valve being configured to seal the outlet portion, and a retracted position. A second portion defining an inlet and an inlet portion of the fluid pathway is lockingly engageable with the first portion. A male valve is disposed within the second portion including a male valve transition member configured to translate the male valve from an extended position to a retracted position including the male valve being configured to seal the inlet portion. The extended position of the male valve causes the female valve to transition from the extended position to the retracted position and causes the outlet portion and the inlet portion of the fluid pathway to be in fluid communication with each other.
