  • Patent number: 10689160
    Abstract: A flexible laminate for a package is described that includes an integrated one-way valve that allows gas generated within the package (e.g., carbon dioxide outgas) to be released to the external environment, while at the same time preventing environmental elements from entering the package. The valve is defined by the layers that form the flexible laminate, as opposed to being a separate structure that is attached to the flexible laminate. In particular, first and second cut lines are defined in a valve area of the first and second film layers of the flexible laminate structure in an offset manner. Oil is pattern-applied to one or both film layers in the valve area, and an opposing surface of one or both of the film layers further includes a surface treatment that decreases the amount of surface energy between the film layers to allow the valve to open at the desired pressure.

  • Patent number: 10227906
    Abstract: An injector which incorporates the use of an insert to compensate for the change in volume of diesel exhaust fluid as the diesel exhaust fluid freezes, reducing or eliminating the effects on the calibration of the injector. The calibration freeze protection insert is located adjacent a calibration sleeve in the injector, where the insert is welded to an inlet tube. Any axial forces applied to the calibration sleeve from the blocking force of the freezing diesel exhaust fluid are transmitted to the insert, and the position of the insert is maintained by the welds. The insert and the calibration sleeve are configured to only allow small amounts of diesel exhaust fluid to migrate around the injector components, which is able to be compensated for by the elastic modulus of the various injector components.

    Abstract: A pressure relief valve is disclosed with a first stage valve that is in series with a second stage valve, with an enclosed cavity between the first stage valve and the second stage valve. The first stage valve relieves pressure from an enclosure into the enclosed cavity between the stages, when the pressure is above a cracking pressure of the first stage valve. The second stage relieves pressure from the enclosed cavity when the pressure is above the cracking pressure of the second stage valve.

  • Publication number: 20140360589
    Abstract: A multiple pressure ratio valve assembly is provided that may be used in a plurality of systems requiring different operating pressures. In one embodiment, a valve assembly and a plurality of interchangeable valves is provided, the interchangeable valves being configured to be installed within the same valve bore diameter, and the valves having different surface areas such that a pressure ratio of the valve assembly may be varied depending on which of the plurality of valves is installed. In some embodiments, the valves may have one or more fluid bypass portions. Embodiments of the invention may also include one or more shims that may be used to further adjust the pressure ratio of the valve assembly. Methods of repairing a valve assembly are also provided.

  • Patent number: 8899256
    Abstract: A male and female set of hydraulic coupler cartridges mate such that one part of the coupler can be left in place, e.g. the female coupler, with the other portion of the coupler, e.g. the male coupler, being removably connected or disconnected. Valves within each cartridge comprise an actuator and springs within each cartridge urge the valves into a closed, sealing position. When the cartridges mate, spring and/or fluid pressure within the cartridges operates to either allow or disallow fluid flow. Once the cartridges are mated, their respective springs are partially compressed and movement of one of the valves operates to compress one spring and correspondingly decompress the other. The cartridges can therefore be mated and unmated, e.g. subsea, while fluid flow is prevented through them during the mating and unmating.

  • Patent number: 8899284
    Abstract: Described herein are several embodiments and implementations of a fluid receiver with a removable sleeve. According to one representative embodiment, an apparatus for receiving a fluid from a fluid source includes a base having an inlet and an outlet. The base defines an interior cavity through which fluid is flowable from the inlet to the outlet. The apparatus also includes a valve that is movable relative to the base between a closed and open position. In the closed position, the valve is in sealing engagement with the base to prevent fluid flow through the inlet. In the open position, the valve allows fluid flow through the inlet. The apparatus further includes a removable sleeve that is removably securable about a portion of the base. The valve remains in the closed position as the removable sleeve is removed from and secured about the base.

  • Publication number: 20140345703
    Abstract: A device for preventing leaks in a toilet that comprises a fill valve operatively connected to and disposed above a float. In certain embodiments an arm is rotably connected to the fill valve such that the arm comprises a pivot. A lever is, for example, pivotally connected to the pivot of the arm and biased towards the fill valve, wherein a flush actuator causes the lever to pivot away from the fill valve. The lever may comprise a first side and a second side joined at the pivot, wherein the first side weighs less than the second side, and wherein the distribution of weight between the first and second sides of the lever causes the lever to bias towards the fill valve.

    Abstract: A method and apparatus for controlling a flow of a fluid through a valve. In one illustrative embodiment, an apparatus comprises an elongate member, an actuation device, and a valve body. The actuation device is configured to move the elongate member, which may be associated with the actuation device, between an open position and a closed position. The valve body is configured for attachment to the actuation device such that the elongate member is positioned within the valve body. Fluid that flows into the valve body from a fluid source is allowed to flow out of the valve body when the elongate member is in the open position.

    Abstract: A piston has a closure face closing off a cavity defined radially inwardly and downstream of an upstream end. The closure face is spaced from the upstream end by a first distance. The piston has a cavity extending in a downstream direction away from an opposed side of the closure face to a second end. A piston diameter is defined to an outer periphery of a cylindrical portion forming a seal face. A ratio of the piston diameter to the first distance is between 3.05 and 6.31. A valve sleeve has windows formed to allow flow of fluid from a sleeve internal bore through the windows and to a downstream port. A ratio of the inner diameter to the axial dimension of the windows is between 0.91 and 1.02. A ratio of the inner diameter to a circumferential dimension of the windows is between 1.55 and 1.85.

    Abstract: A manual valve operator with override clutch apparatus is disclosed for selectively actuating a valve. The apparatus includes an operator housing defining an enclosure. An input shaft is rotatably supported by the housing and a worm wheel has a first and a second side, the second side of the worm wheel defining a clutch drive. The worm wheel is disposed within the housing and intermeshes with the input shaft such that when the input shaft is driven, the input shaft drives the worm wheel and the clutch drive about a rotational axis. A sleeve has an outer surface which defines an annular groove. The sleeve has a driven end and an output end. The driven end of the sleeve cooperates with the clutch drive of the worm wheel for selective engagement of the clutch drive and the driven end of the sleeve. A clutch actuating handle is rotatably supported by the housing. The clutch actuating handle has a first and a second end.
