  • Patent number: 8430731
    Abstract: A device for controlling an airflow in a ventilation duct, comprising a pivotable air flap, which prevents an airflow in the duct when in the closed position. A housing of an actuator for the air flap, which may pivot freely about the relevant longitudinal mid plane, is mounted in the inner duct wall. The air flap, symmetrically or approximately symmetrically curved about the longitudinal mid plane of the ventilation duct and supported under load in a stable position on the duct wall, is rigidly fixed to the driveshaft of the actuator, by an angled lever arm, with a separation, in the region of the apex line thereof. The air flap rests roughly centrally, permanently on the points of contact with the inner duct wall, which move with the position of the flap, in a self-centering manner and, in the closed position, contacts the inner duct wall along a sealed, endless peripheral sealing surface.

  • Patent number: 7458385
    Abstract: A flapper valve for push-in snap-lock attachment to a spud to be welded to a fuel tank and attached to a flexible filler tube hose. The flapper has an annular flexible seal overmolded thereon, preferably of elastomeric material. The flapper has a pair of trunnions, one of which has an extension or spindle with a resilient member received thereover with one end of the resilient member slidably anchored to a post on the flapper to form a flapper subassembly. The opposite end of the resilient member is deflected to fit in a slot or groove in the body when the trunnions are snapped into a slot formed by at least one deflectable portion formed integrally on the exterior of the tubular valve body for pivoting the flapper. Deflector vanes are provided on the upstream side of the flapper to protect the seal from the end of a siphon hose.

  • Patent number: 7458394
    Abstract: A servovalve assembly includes a motor having a flapper shaft. A flapper couples to a first end of the flapper shaft such that the flapper shaft orients the flapper between a first nozzle and a second nozzle of the servovalve assembly. An adjustment assembly adjusts a position of the flapper relative to the nozzles of the servovalve. The adjustment assembly enables a servovalve manufacturer to set the flapper of the servovalve at a null position without disassembling the servovalve. Rather, the manufacturer is capable of simply installing the adjustment assembly and deforming an arm portion of the adjustment assembly for proper null position calibration.

  • Patent number: 7063099
    Abstract: The present invention is directed to an exhaust gas control (EGC) valve. The EGC valve comprises a valve housing having at least one inlet port, at least one outlet port, and a flow channel having a centerline extending between the ports. A valve seat is adjacent an opening in the at least one outlet port. The EGC valve further comprises a rotatable actuator shaft offset from the centerline. At least one L-shaped valve armature is operably connected to the actuator shaft. The valve armature has a first leg and a second leg. The first leg is connected to the actuator shaft so that rotation of the actuator shaft in a first direction positions the second leg into sealing engagement with the valve seat to close the flow channel.

  • Patent number: 6688321
    Abstract: A device for regulating the flow of gas from an environment. The device includes a shell forming a path through which fluid flows. A fixed grate is disposed in the path so that as fluid flows in the path the fixed grate does not move. A movable grate assembly includes one or more plates and a movable grate attached to the one or more plates. The one or more plates includes an integral hinge such that the plate can rotate about the integral hinge. When the movable grate moves with respect to the fixed grate the impedance on the flow varies.

  • Patent number: 6679289
    Abstract: The present invention relates to a light weight check valve for use in bulk material transfers that incorporates a smooth, generally spherical interior cavity to minimize flow inefficiencies. The check valve is made from two portions: a body portion and a lid assembly which is removably mounted to the body portion. The gate valve, or poppet, is hingedly mounted to the lid assembly. Hence, when the check valve assembly is opened for inspection, by removing the lid assembly, the poppet is removed along with the lid assembly, to allow for easy inspection of the poppet.

  • Publication number: 20020124886
    Abstract: A self-actuating damper for each slot of a multi-slot printed circuit board assembly cage allows proper air-cooling without regard to the presence or non-presence of card board assemblies in the slots. The damper of each slot is automatically held in the closed position when the respective slot is empty. An actuation hook implemented on each of the card board assemblies engages the actuator of the damper as card board assembly is aligned with the slot and automatically actuates the damper to an open position as the cell board assembly is inserted into the slot.
