A coupling assembly (10) is reconfigurable among three states. In a disconnected state, a spring-biased lock indicator (20) is in a first lock indicator position, and the lock indicator includes a restriction member (40) that in the first lock indicator position retains an actuator in a first actuator position such that a valve is in a closed position and a locking pin is in a retracted position. In a connected/valve-closed state, the lock indicator (20) is in a second lock indicator position in which the restriction member (40) permits movement of the actuator (30), but with the actuator (30) still being in the first actuator position such that the valve is in the closed position and the locking pin (46) is in the retracted position. In a connected/valve-open state, the lock indicator (20) is in the second lock indicator position to permit movement of the actuator (30), and now with the actuator (30) being in the second actuator position such that the valve is in the open position and the locking pin (46) is in an extended position to lock a second coupling assembly to the coupling assembly to form a unisex coupling connection.

The invention relates to a device for sealed transfer between two enclosed volumes, comprising a first flange and a second flange (10) which define a passage opening into the enclosed volumes and can be secured to each other by a first bayonet connection, a first door and a second door (11) which close off the passage openings and can be secured to each other by a second bayonet connection, the first door (11) being hingedly mounted on the first flange (10) by means of a hinge (4) comprising a hinge pin, characterized in that the device comprises an external manual control lever (9) which is secured to a rotary pin penetrating the first flange (10) and which is coupled to the hinge pin in such a way that the actuation of the control lever (9) drives the hinge pin, thus opening or closing the first door (11).

The present invention relates to a hydraulic and/or pneumatic multi-coupler connector of the type comprising at least one pair of couplers inserted into a containment body and equipped with a lever actuated mechanism comprising an actuation lever maneuverable by the user for the relief of the residual pressure of the couplers and the connection thereof to corresponding male couplers.

This document describes fluid handling couplings. For example, this document describes fluid handling couplings that include manually openable valves and that are configured for aseptic fluid handling usage. In some embodiments, the valves are manually openable by rotation of a collar of the fluid handling couplings.

A connector including a plug and a socket. The socket includes: a socket body having an insertion hole formed therein; a columnar rotary valve inserted into the insertion hole; and a switching mechanism for switching an open state and a closed state. The rotary valve includes a pair of convex portions respectively in contact with both ends of the insertion hole to seal an outflow of a liquid; and a concave portion provided between the pair of convex portions and forming a cleaning space) in which a cleaning fluid is circulated between the concave portion and an inner peripheral surface of the insertion hole. The socket body includes a cleaning fluid inflow passage for guiding the cleaning fluid to the cleaning space and a cleaning fluid outflow passage through which the cleaning fluid flows out of the cleaning space.

A fluid system coupling includes an adaptor, a coupler, and an actuation mechanism. The adaptor has an adaptor poppet that is movable between an open position and a closed position. The adaptor poppet has a poppet face that is substantially planar and devoid of any recesses. The coupler has a coupler poppet that is movable between an open position and a closed position. The coupler poppet has a poppet face that is substantially planar and avoid of any recesses. The actuation mechanism selectively moves the poppets from the closed positions to the open positions.

Disclosed is a female coupling member which includes a housing having a fluid passage extending therethrough, a valve member selectively opening and closing the fluid passage, and a valve open-closed state indicating member. The valve open-closed state indicating member has a valve open state indicating part and a valve closed state indicating part and is displaced in response to the displacement of the valve member. When a male coupling member is connected to the female coupling member, and when the valve member is in an open position, the valve open state indicating part is visible from the outside of the housing through a window of the housing, whereas, when the valve member is in a closed position, the valve closed state indicating part is visible from the outside of the housing through the window.
