  • Patent number: 5820162
    Abstract: A spool valve controls the release of gas from a pressure vessel into an airbag upon the release of the gas in the event of a collision. The valve uses pilot pressure acting on either end of the spool to actuate the spool. The position of the spool within the valve determines the flow rate through the valve.

    Abstract: A fluid dispenser for dispensing various types of viscous fluids has a valve which is capable of operating at high speeds. The valve has a stiff diaphragm spring which moves an armature which has a relatively large pole face area directly opposite the end faces of an inner and outer core. So that movement of the armature is not interfered with by the fluid material above or below the armature, openings are provided through the armature for the flow of the fluid material. The armature is positioned close to the cores, and is provided with a short stroke, so that the air gaps in the flux loop between the armature and the cores are small, reducing the reluctance of the magnetic circuit and thus increasing the amount of force produced by the coil.

  • Patent number: 5535919
    Abstract: An electromagnetic dispenser for dispensing viscous heated fluids, such as hot melt adhesives. A fixed pole extends from a fluid chamber. The coil is located about a portion of the fixed pole and spaced from the fluid chamber to isolate the coil from the fluid flow path of the adhesive. The coil is insulated from the heat which is conducted from the adhesive as well as provided with a heat sink for dissipating heat. A plunger is mounted within the fluid chamber for reciprocal movement therein to open and close dispensing orifice in response to the field generated by the coil. When mounted to a service block, the coil assembly may be serviced without disconnecting the dispenser body from the source of heated fluid.

  • Patent number: 5524794
    Abstract: A metering device for controlling the flow of granular material from a container. The metering device includes an electromechanical solenoid connected to a pivoting metering bar. When the solenoid is energized, the metering bar is pivoted away from an outlet aperture, permitting the flow of material from the container. When the solenoid is de-energized, a spring causes the metering bar to pivot into contact with the outlet aperture, closing the outlet aperture and stopping the flow of material from the container.

  • Patent number: 5507323
    Abstract: Methods and dispensers which are used for a new way of filling liquid crystal into a LCD cell. The invented methods use the invented liquid crystal dispenser able to release liquid crystal with sufficient controllability at an evacuated atmosphere. Liquid crystal is filled through an inlet of an assembled LCD cell, or filled by laminating an upper substrate with a lower substrate on which liquid crystal has been dropped. The invented liquid crystal dispensers have an opening, in addition to the opening for a capillary, through which interior air bubbles can be released out so as not to be released from the capillary.

  • Patent number: 5495963
    Abstract: A variable restrictor valve for use in an intermittent dispensing system having a recirculation loop. The restrictor valve establishes a more linear relationship between the amount of adjustment made thereto and the resulting pressure drop over the restrictor valve in the recirculation loop. A first embodiment of the restrictor valve changes the length of the flow path created by a helical groove to thereby adjust the flow resistance through the valve. A second embodiment uses a valve member in the form of a perforated cylindrical tube which is adjustable to present a varying number of perforations as the inlet to the tube and thereby allow adjustment of the flow resistance. A third embodiment utilizes a helical spring as a valve member in which adjustable spacing between the coils of the spring provides adjustability of the flow rate through the spring.

  • Patent number: 5494189
    Abstract: A metering device for controlling the flow of bulk material, contained in a bulk material container, out through a flexible pouring spout on the bulk material container, so that the flexible pouring spout may be tied shut and later un-tied for re-use of the bulk material container. The metering device is positioned below the bulk material container which is to be emptied, upstream from the plant process operation which is to receive the bulk material from the container. A metering gate discharger, contained within the metering device, provides accurate batching from the bulk material container as well as the ability to completely empty the bulk material container at one time without metering the contents.

  • Patent number: 5489047
    Abstract: An aerosol spray can and selectively-operable valve mechanism for dispensing the contents of the can to an environment are assembled to one another in operable relation using an adaptor structure which comprises an element snap-fit mounted to the aerosol can and a further element snap-fit mounted or otherwise affixed to the valve mechanism. The elements are provided with mating screw threads, which permit the assembly to be readily and securely effected. The adaptor elements are moulded parts constructed to be resiliently flexible to a degree to assist in mounting and demounting from the element to which it is to be attached and yet to resist such flexure when assembled together.

  • Patent number: 5458151
    Abstract: A solenoid controlled valve is mounted in a threaded opening of a pressure vessel which contains compressed natural gas. The valve includes a valve body having a head, which is exposed outside of the pressure vessel, and a neck, which is located within the pressure vessel. A solenoid poppet valve is mounted to the inner end of the neck. A valve seat is mounted in a bore within the valve body. All orifice at an inner end of the valve seat exposes a flow passage between the bore of the valve body and an outlet port, which is located in the head of the valve body. The solenoid poppet valve includes a seal for closing the orifice, a bias spring which biases the seal toward the seat to close the orifice, a plunger which is connected to the seal, and a solenoid coil which, when energized, moves the plunger so that the seal moves out of engagement with the seat and permits flow of compressed gas from the interior of the pressure vessel to the outlet port.
