  • Patent number: 9080686
    Abstract: The invention relates to a valve particularly for transferring small portions of glue onto folding tabs of (cigarette) packs. A closing element (15) of the valve is actuated by different elements, that is to say, is moved between the open and closed positions, on the one hand by two permanent magnets (24, 25) arranged a short distance from each other and having aligned poles such that the closing element is permanently kept in the closed position by the permanent magnets (24, 25). On the other hand, an actuating element, which is configured as an electromagnet (23), acts to move the closing element (15) into the open position in a controlled way by overcoming the closing forces. The closing element (15) is designed in a particular way, that is to say, with channels extending along the outside in the longitudinal direction for the medium or the glue.

  • Publication number: 20110023513
    Abstract: A refrigerant expansion valve for a refrigerant system includes a main body, a motor and first and second members. The main body has a refrigerant flow passage that extends therethrough. The first and second members are connected together and are configured with threads that have a different pitch to allow for relative movement between both members and the main body. The motor is positioned adjacent the main body and is coupled to the first member. The motor actuates the first member in response to control signals to move the second member within the main body to modulate the flow of refrigerant through the refrigerant flow passage.

  • Patent number: 7819385
    Abstract: A threadform for a gate valve has a set of threads on a stem that engage a threaded receptacle of the gate. When the stem is rotated, the gate moves. The threads have a thread height to thread base thickness ratio that is at least the inverse of 0.7 times e raised to 0.388 divided by a nominal thread diameter of the threads. That ratio is at least 1.1.

  • Publication number: 20100163772
    Abstract: In one embodiment, a fluid driven actuation system is provided having a turbine and an actuation member with cooperating surfaces. In one form the fluid is fuel. The turbine may move when fluid is flowed through the actuation member thereby causing the actuation member to move by action of the cooperating threaded surfaces. A movable nozzle may also be provided to direct fluid flowing through actuation member and may be used to cause the turbine to move. A spring may be provided to create a biasing force in the nozzle.

  • Patent number: 7721755
    Abstract: A valve assembly to dispense fluid from fluid containers including a member that is rotatably slideable in a tube between open and closed positions. The valve assembly utilizes sealing beads to provide seals so that fluid cannot be dispensed from the assembly when the assembly is in the closed position. The valve assembly also includes a tamper evident indicator to show a user whether or not the valve assembly has been previously actuated. The tamper evident indicator may include a tab that is broken when the valve assembly is first actuated. The tamper evident indicator may also include a skirt that either detaches from a knob or fractures when the valve assembly is first actuated.

    Abstract: An air valve includes a tubular seat, a cap, and a plug. The tubular seat has an outer circumferential surface forming sealing slots, first external thread and second external thread and also forms an axially-extending air passage. The cap has an inside circumferential surface forming first internal thread, second internal thread, and a barrier web. The barrier web forms a bore and a plurality of air holes. The cap has a distal open end to which a lid is mounted. The plug has an expanded proximal end to which a sealing pad is attached and a reduced section slidably received in the bore of the barrier web and having a distal end to which a stop is mounted so that the plug is axially movable with respect to the barrier web.

  • Patent number: 7694939
    Abstract: A retaining cylinder is threadedly engaged with a fixed cylinder of a flow rate control valve, by means of a screw section formed on an outer circumferential surface. A fence cover, which is capable of expanding and contracting in the axial direction, is installed between the fixed cylinder and a float rod supported by the retaining cylinder. An upper seal member is provided on the float rod, on the upper side thereof with respect to a valve plug. A lower seal member is provided on the lower side thereof with respect to the valve plug. The upper seal member and the lower seal member have substantially identical diameters. The float rod is displaced under an energizing action of a stepping motor. The flow rate of a fluid is controlled depending on a distance of the valve plug with respect to a valve seat.

  • Patent number: 7694692
    Abstract: A non-magnetic latching servo actuated valve under the control of a controller comprising a motor in rotational communication with a lead screw. The lead screw advances or retracts a valve stem connected to a valve stem cap. The valve stem cap has a valve stem cap passage. A valve end cap having a valve seat is provided and receives the valve stem cap such that the valve stem cap can contact the valve seat. A pressure relief device or shuttle assembly is positioned internal to the valve stem cap. The shuttle assembly is used for venting build-up downstream pressure through the non-magnetic latching servo actuated valve outlet, through the valve stem cap passage, around the shuttle assembly, through passages, into a pressure chamber, and to the non-magnetic latching servo actuated valve exit where the fluid vents until the system is in balance.

  • Publication number: 20100012876
    Abstract: An adapter for gas valves used for fireplaces and barbecues. The adapter bridges a distance between the gas valve and a finishing flange used to cover a hole in a floor or wall within which the gas valve T-junction is recessed. The adapter includes an inner length with female threading adapted to mate with the male threading on a valve control leg of the gas valve T-junction, and an outer length with male threading adapted to mate with the female threading on the finishing flange. The threading on the gas valve T-junction, adapter, and finishing flange is all parallel enabling maximum axial adjustment therebetween, and eliminating the need for expensive plumbing work to couple pipe elements with tapered threading therebetween. Multiple adapters may be coupled together to bridge longer distances. A gas key having an adjustable length couples with the adapter to provide fine length adjustment. The adapter may be a machined metal tube or a molded plastic element.
