The female element further includes a control member mounted to slide in an open bore in the body for causing the latch to move at least towards the second position.

Abstract: A full flow quick connect fluid coupling that reduces spillage using a convex and a concave ball valve mounted each in a separate coupling body that are joined together where the ball valves seal together and are sequentially rotated using one activation lever to first rotate a first ball valve 90 degrees and then rotating a second ball valve 90 degrees using a gear drive mechanism. A handle button release lock and a secondary handle lock ensure that the valves are not opened until the bodies are joined and locked together in sealing engagement. A lock mechanism is used to lock the bodies together and to provide a lock tab that prevents the ball valves from being opened until the lock mechanism is closed.

Abstract: Known fluid dispensers can suffer from the disadvantage of inadvertent disconnection of a connector causing potentially hazardous spillage of fluid. The present invention relates to a fluid dispensing assembly comprising a tap and a connector body. The tap comprises a first valve, movable between an open and closed position to allow fluid flow through; and a first portion of an interlocking coupling, configured for rotational engagement with a second complementary interlocking coupling portion of the connector body by rotation about a first fluid dispensing assembly axis. The connector body also comprises a second valve, movable between an open and closed position to allow fluid flow through. By this configuration, the first and second interlocking coupling portions remain interlocked preventing disconnection of the connector body from the tap unless the first and second valves are both in the closed position.

An interlock system is configured to permit movement of the valve member from the closed position to the open position when the complementary coupling is connected to the body at the interface, and to prevent movement of the valve member from the closed position to the open position when the complementary coupling is not connected to the body at the interface.

Abstract: A mounting assembly uses one hinge and one cam bolt mutually offset upon a two piece collar. A hopper tee has a member usually a vertical pipe and occasionally a horizontal pipe that connects to a hopper flange to receive bulk material. This assembly has two collars that mutually engage and surround a hopper flange. Pins pass through the collar pieces and the hopper flange then secure to tapped holes in the collar pieces to prevent rotation. A collar piece mounts a hook bolt and the other collar piece mounts a hinge in a spaced apart and offset manner. The other collar piece has a pivotal connection to a hinge arm and opposite the hinge arm, the hook bolt engages a cam. Opening the cam unfolds the tee downwardly while the hook bolt remains engaged. This partially open position allows for removal and installation of a valve. In opening and closing the assembly, the hinge arm spaces the flange below a hopper to admit a valve.

The nut is sealed to the system, and the nut is rotated to move the bleeder valve to an open position while maintaining the seal between the nut and the fluid system. A passage within the body and the nut provides for evacuating the system and then charging fluid into the system. The nut is rotated to move the bleeder valve to its closed position, and the nut is then unclamped and unsealed from the fluid system. In one embodiment, the bleeder valve is gripped to clamp and seal the nut to the fluid system, and in another embodiment, the nut is sealed to the system using a clamping member opposing the nut.

Abstract: A coupling (110) comprising a pair of female couplers (116) each independently movable within a respective housing bore (114) among an operating position, a release position, and a coupling position. When a female coupler (116) is moved to the coupling position, a stop member (136) moves the plunger of a pressure relief valve (124) to an open position to allow fluid to be released from the female coupler (116) prior to coupling a male coupler thereto. A cam member (126), which is used to move the respective female coupler (116) from the operating position to the release position, can move away from the plunger when the female coupler (116) is in the coupling position as the pressure relief valve (124) is held open by the stop member (136).

Abstract: A fluid system component is provided that includes first and second elements configured to be removably engaged with each other and defining a fluid passageway when engaged. The first element defines three grooves, each of which includes a terminal portion. Correspondingly, the second element includes three engagement members each of which is configured and arranged to be received in, and travel along, a corresponding groove. The presence of a predetermined line pressure in the fluid passageway forces each engagement member into the terminal portion of the corresponding groove, so as to substantially foreclose disengagement of the first and second elements until the fluid pressure in the fluid passageway has reached a predetermined magnitude.

Abstract: This disclosure is concerned with fluid system components. In one example, A quick disconnect valve assembly includes first and second valve elements configured to releasably engage each other. Each valve element includes a housing that defines a valve seat and a fluid passageway. A plunger is disposed within each housing and arranged for selective engagement with a corresponding valve seat. Each plunger is biased into a sealing engagement with the valve seat by a resilient element disposed within the housing. Consequently, the fluid passageway of each valve element is closed off when the first and second valve elements are separated from each other. When the valve elements are engaged, the respective biases associated with the plungers counteract each other to the extent that each plunger is lifted off the corresponding valve seat and fluid communication is established between the respective fluid passageways of the first and second valve elements.

A stem, located in the valve bore, includes first and second stem seals, and a stem bore in fluid communication with a hose fitting and an outer surface of the stem between the seals. The stem is movable between valve open and closed positions by moving a valve handle. A rotation limiting member coupled to the stem and slidably coupled to the external body limits the rotation of the stem. A locking sleeve coupled to the external body moves between a secure position and a release position. The locking sleeve interferes with the valve handle position when the locking sleeve is in the release position to prevent opening the valve when not connected to the port.

Abstract: A fluid flow management system that includes a feedback system in communication with a fluid system component having discrete elements that, when joined together, define a joint and chamber. The fluid flow management system further includes a feedback fluid source in fluid communication with the chamber and with a pressure transducer. The feedback fluid source, transducer, and chamber collectively define a substantially closed system so that fluid introduced by the feedback fluid source eventually reaches static equilibrium. Separation of, or relative movement between, the discrete elements of the fluid system components permits fluid to escape the chamber, thereby causing a pressure change that is detected by the pressure transducer. The pressure transducer then generates and transmits a signal indicating a loss of joint integrity. The signal may be used to aid in the implementation of various actions concerning the system wherein the fluid system component is employed.

Abstract: A device couples two storage and/or transport units with a security device. By alternately using a single actuating device, the security device and a pivoting device react in such a way that connecting branches of the units which are coupled are placed in a lock position by the security device and are firmly locked with respect to each other such that it is not possible to separate them. Closing valves in the connecting branches insure that the connecting branches are sealed from each other. By subsequently rotating the drive shaft, it is possible to open the closing valves using the pivoting device in order to enable a transfer process to occur. By rotating the drive shaft back, the closing valves are re-closed. Also by rotating the drive shaft, the connecting branches can be separated from each other.
