  • Publication number: 20150122358
    Abstract: Disclosed valves for drinking from a portable fluid container allow for manual actuation of the valve between an open configuration that permits fluid flow and a closed configuration that substantially prevents fluid flow. Disclosed valves comprise a valve housing having inner bore fluidly coupled to an inflow channel and an outflow channel that are angled with respect to one another, and a reciprocating valve member that is adjustably positioned partially within the bore to open and close the fluid flow pathway through the bore from the inflow channel to the outflow channel. The reciprocating valve member is shaped such that it can prevent fluid flow when fully inserted within the bore to a closed configuration, and can allow fluid flow when the valve member is retracted from this closed position by a relatively short distance to an open configuration.

The piston (126) h a leading face (128) that is also orientated at 60 degrees, so that the flow passage/melt channel (118) extends past the leading face (128) when the valve (110) is open and the leading face (128) forms part of the bounding wall of the mould cavity (114) when the valve is closed. The piston (126) is advanced or retracted a very short distance and is rotated through 180 degrees, to open and close the valve (110).

  • Publication number: 20140197345
    Abstract: Piston actuators and methods of its operation are described. The piston actuators include a housing defining a chamber having a piston therein and a spring seated against the piston to bias it into a starting position. The piston includes a ferromagnetic material, a magnet or both and a secondary magnet or ferromagnetic material, forming a first magnetic/ferromagnetic pair with the piston, is positioned to maintain the piston in a secondary position. A tertiary magnet or ferromagnetic material, forming a second magnetic/ferromagnetic pair with the piston, may assist the spring in maintaining the piston in the starting position. During operation, introduction into or removal from the chamber of an amount of fluid sufficient to overcome the force of the spring (and the tertiary magnet or ferromagnetic material) enables the attraction between the members of the first magnetic/ferromagnetic pair to move the piston to the secondary position as a snap movement.

  • Patent number: 8720467
    Abstract: A purging device is provided for an assembled unit for a vehicle, having both a wheel including a rim and a tire. The purging device has a body connected to the inflation tube of the assembled unit, the body being designed to be subjected to the inflation pressure of the assembled unit, and a piston able to move inside the body. The piston operates an open/close element, fixed to the piston, between a closed position and a purging position of the body, the open/close element being normally closed, the open/close element and the piston each having a face designed to be exposed to the inflation air inside the body in the closed position. The open/close element is opened by the action of an operating force on the piston. Also disclosed is a method for deflating an assembled unit.

  • Patent number: 8714515
    Abstract: A hydraulic actuating device for a sliding stem control valve assembly is mounted between a control valve and an actuator housing. The hydraulic actuating device is connected to one of a control valve stem, an actuator stem, and a stem connector and the hydraulic actuating device moves either the control valve stem, the actuator stem, or the stem connector in response to varying hydraulic pressure within the hydraulic actuating device. The hydraulic actuating device may be used to override an actuator of the sliding stem valve during emergency operations, or to provide a backup actuator in the case of a primary actuator malfunction.

    Abstract: Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves having a pliant valve piston and/or plug that exudes silicone oil when stressed or squeezed while providing antimicrobial agents within and on the surface of the piston and/or plug. The pliant valve piston may have an integrally formed plug and one or more ports or a separately formed plug located inside a plastic housing. The plug cooperates with a nozzle on the inlet connector assembly to form a slip port or a Luer inlet, which can open when exerted by force to permit flow or closes when the force is removed.

    Abstract: A valve is provided for controlling flow along a fluid line that includes an outer shell and an inner housing slidably disposed therein that includes connector threads surrounding a boss on one end and a passage through the boss. A backing member is coupled to the outer shell and has a sealing pin extending into the passage. The inner housing is movable helically relative to the outer shell from a closed position wherein a sealing pin engages an outlet opening at the distal end of the boss to seal the opening and an open position in which the inner housing is directed away from the sealing pin to open a fluid path through the valve. A torque limiter mechanism between the outer shell and inner housing resists movement from the valve closed position to the valve open position until a selected torque level is reached.
