Removable Valve With Normally Disabled Supplemental Check Valve Patents (Class 137/329.1)
  • Patent number: 9694171
    Abstract: A needleless connector has a body having an internal cavity with a sealing ridge, a port, an output flow channel, and a fluid flow path between the port and output flow channel. The connector also has a collapsible valve disposed within the cavity. The valve includes a cylindrical wall having a center axis, an internal surface, and a shoulder configured to sealingly contact the ridge of the body, thereby blocking the fluid flow path. The valve also includes a head fixedly attached to the wall. The head has a smiley cut at a first angular position about the center axis and a continuous top surface that is generally perpendicular to the axis. The valve also includes a first dimple formed in the internal surface of the cylindrical wall. The dimple extends around the internal surface over an angle in the range of 90-270°.

  • Patent number: 9434594
    Abstract: A beverage dispenser is disclosed that includes a cleaning adapter configured to form a cleaning space in which each syrup nozzle and a dilution water supply section are located between the cleaning adapter and a multivalve and to clean each syrup nozzle by dilution water discharged from the dilution water supply section. A gap between the cleaning adapter and the multivalve is sealed above a nozzle distal end portion of each syrup nozzle and the dilution water supply section. The cleaning adapter includes discharge port 71 that discharges the dilution water after cleaning each syrup nozzle from a position higher than the nozzle distal end portion of each syrup nozzle.

  • Publication number: 20090205721
    Abstract: A burst disc replacement apparatus (100) comprises a magazine (122) that carries a first burst disc (232) and a second burst disc (234). A flow path (104) passes through the apparatus (100) for venting fluid. The first burst disc (232) is located in the flow path (104). A translation mechanism (112, 144, 146, 200, 214, 220, 222) is arranged to move the second burst disc (234) into the flow path (104) in place of the first burst disc (232) in response to an indication that fluid pressure at one side of the first burst disc (232) has exceeded a predetermined pressure corresponding to rupture of the first burst disc (232).

    Abstract: A burst disc replacement apparatus (102) comprises a magazine (114) carrying a first burst disc (116) and a second burst disc (118). The apparatus also comprises a flow path (104) therethrough for venting fluid. The first burst disc (116) is located in the flow path (104) and the second burst disc (118) is located outside the flow path (104). A translation mechanism is also provided and coupled to the magazine (114) and arranged to permit manual translation of the magazine (114) so that the second burst disc (118) moves, when in use, into the flow path (104) in place of the first burst disc (116).

  • Patent number: 6189560
    Abstract: A secondary valve unit is provided to interconnect a front/finish assembly and an existing wall outlet for supplying medical gases. The secondary valve unit includes a cylindrical body containing a secondary valve assembly to prevent gas leakage when the front unit that contains a primary valve is removed for services. The secondary valve unit is pre-assembled and threadedly connected to the wall outlet. The threaded connection is locked by an indexing plate which is attached to the wall and provides indexing connection with the front unit to avoid mistakenly connecting a wrong front unit for different gases. The secondary valve unit is especially used in renovations of medical gas systems in hospitals, and able to be installed to an existing wall outlet without breaking the wall so that the cost for renovations is significantly reduced. The connector assembly for gases using the secondary valve unit provides a great gas flow and achieves a more secure connection over a long period of time.
