The invention relates to a connection fitting (102) for a valve coupling and/or measuring or test coupling (2) for fluid systems for detecting working pressures of fluid media, the coupling (2) comprising a coupling bushing (6) which is subject to operating pressure in the installed state and which has a connection part (16) and a borehole (10) in which a spring-loaded and mechanically actuatable non-return valve (32) is arranged, the valve body (18) of which, in the non-actuated state, is supported on a valve seat (52), the connection fitting (102) having an opening pin (114) having a more particularly circular, closed contact surface for the valve (32) and at least one passage (118) extending laterally to the contact surface, through which passage a connection can be established between the connection fitting (102) and the valve coupling and/or measuring or test coupling (2).

The connection assembly (100) which includes a flange (140) has two internal orifices (150) crossing through and centered on orifice axes (A150) parallel to each other, a front surface (142) and a rear surface (144) parallel to a transverse plane (P140) transverse to the orifice axes (A150), two fluidic coupling elements (170), that have a male body (172) received in a corresponding internal orifice, and a cover (120), configured for being attached to a support (110) in a mounted configuration of the connection assembly. The flange can move with respect to the cover according to a movement supported by the transverse plane, whereas for each male body, a second gasket (188) is interposed radially between the male body and an internal radial surface (S162) of the corresponding internal orifice, each male body being mounted in the corresponding internal orifice and can be tilted with respect to the corresponding orifice axis.

A fluid coupling including a first adapter, a second adapter configured to selectively connect with and disconnect from the male adapter, an inner sleeve, a first seal between the first adapter and the inner sleeve, a second seal between the second adapter and the inner sleeve, and at least one thermally-activated seal between two of the first adapter, the second adapter, and the inner sleeve. During normal operation, the at least one thermally-activated seal may be spaced apart from at least one of the two of the first adapter, the second adapter, and the inner sleeve. At or above a predetermined temperature, the thermally-activated seal may be configured to expand to create a seal between the two of the first adapter, the second adapter, and the sleeve.

A manifold for a medical waste collection apparatus includes a fluid path connection portion and a storage connection portion. The storage connection portion includes a mounting connector in communication with the fluid path connection portion and coupled with the mounting base of the waste collection apparatus, and a docking valve arranged inside a connector cavity defined by inner walls of the connector. The docking valve is in an open state when the mounting connector is coupled with the mounting base, and a passage is formed between the storage connection portion and a waste collection container in the waste collection apparatus. The docking valve is in a closed state to close the connector cavity when the mounting connector is decoupled. The connection port between the manifold and the apparatus does not require manual opening or closing, thereby preventing waste from contaminating the environment, equipment and personnel, and enhancing convenience of use.

A valve fitting includes a fitting body defining a fitting passageway, supply and working ports in fluid communication with the fitting passageway, a supply port coupler operable to connect the supply port with an associated feed port coupler providing a pressurized fluid, a working port coupler operable to connect the working port with an associated tire of a tire assembly of an associated work vehicle, a supply valve moveable in the fitting passageway between a first position closing the fitting passageway from the supply port and a second position opening the fitting passageway to the supply port, a biasing assembly biasing the supply valve towards the first position, and an actuator assembly comprising an actuator member operable to urge the supply valve towards the second position against the bias of the biasing assembly in response to the associated feed port coupler being connected with the supply port coupler.

Insertion fitting/coupler devices for coupling to a flowpath, and methods of using such insertion fitting/coupler devices, are disclosed. The insertion fitting/coupler devices include a coupler that includes a through hole and a stem portion. The insertion fitting/coupler devices also include a nut that includes a through hole, a rim and a body portion. The insertion fitting/coupler devices further include a body member that includes a through hole and an outer flange. The body member extends into the through hole of the coupler such that an end of the stem portion of the coupler engages the outer flange of the body member. An inner side of the body portion of the nut engages with an outer surface of the stem portion of the coupler such that the flange is secured between the rim of the coupler and the end of the stem portion of the coupler.

A safety coupler for an air hose terminating in a plug. The plug has a passageway between its first and second ends for the passage of air there through. The coupler member has upstream and downstream ends and first body coupler passageway sized for receiving a first cylindrical section of the plug and terminating in a washer. A sleeve coupler and spring for biasing the sleeve coupler towards the coupler member upstream end, the sleeve coupler terminating at its coupler member upstream end by a bushing plug being sized to create a shoulder for abutting a raised stop of the plug. A reduced diameter plug receiving passageway is located downstream of the sleeve coupler and is sized to receive the plug and for receiving pressurized air passing through the plug passageway, and a sleeve slide valve threadably engageable to the washer such that when the plug enters the coupler member, the plug having a raised stop abuts the first body coupler resulting in the washer being displaced towards the coupler member downstream end whereupon the sleeve slide valve threadably captures the washer preventing the plug from disconnecting from the coupler member.
