  • Patent number: 8627851
    Abstract: A multi-position valve assembly including a valve housing, a stator element and a rotor element rotatably mounted about a rotational axis. The valve assembly further includes a pressure adjustment assembly movable between a release position and a stop position, hard stopped relative to the valve housing. The pressure adjustment assembly includes a pressure adjuster device configured to movably cooperate between the rotor element and the valve housing to adjustably generate an axial compression pressure at the rotor-stator interface at a calibrated operating pressure, PC. When the pressure adjustment assembly is oriented in the release position, the axial compression pressure is substantially removed from the rotor-stator interface. In contrast, when the pressure adjustment assembly is oriented in the stop position, the axial compression pressure is substantially reproduced at the calibrated operating pressure, PC.

  • Patent number: 8590557
    Abstract: A dual flap device for the environmentally tight connection of two receptacles is provided with two housing halves, which can be releasably connected. Each housing half accommodates a flap, which is pivotable by way of a half shaft. In a connected position of the dual flap device, the housing halves and the flaps rest against each other and are tensioned against one another, respectively. The half shafts of the two flaps unite to form a mutual shaft having a rotational axis. Thus, using a locking device, both flaps can be pivoted between a closed position and an open position by way of the mutual shaft. A first housing half is provided with a locking device, at least on one side, located in axial extension of the respective half shaft, which makes it possible to switch the dual flap device between an unlocked and a locked position.

  • Patent number: 7836909
    Abstract: A rotatable wedge valve mechanism has a valve body or valve cartridge defining a valve chamber and flow ports in fluid communication with the valve chamber. A valve seat is located within the valve chamber in registry with one of the flow ports. A non-rotatable core member having a convex external surface portion is supported within said valve chamber. A wedge member is mounted for rotation within the valve chamber and has a range of rotary motion between open and closed positions of said valve and a non-uniform wall thickness throughout said range of rotary motion. An actuator upon rotary movement achieves opening and closing rotation of said wedge member. A method is provided for machining concave and convex wedge member surfaces from selected center-points to achieve relative thicknesses of wall sections of the wedge member.

  • Patent number: 7350536
    Abstract: A portable receptacle is vacuumized for use in taking an air or gas sample for subsequent examination to determine type, origin, components of the air or gas. Critical to a long shelf life of the vacuumized receptacle is a valve which virtually seals the receptacle for months or years permitting storage of the receptacle in a state ready for immediate use at a site. The valve utilizes a positionable member plated with a noble metal. A filter serves to collect particulate from the air or gas flow into the receptacle. A funnel shaped collector aids in the collection.

  • Patent number: 6769445
    Abstract: A gear meshing with a pinion controls the angle of rotation of a valve element which is brought into sliding contact with a valve seat, thereby controlling the opening and closing of a communicating hole of outflow pipe. During welding the valve seat plate and a housing, a hook portion of an upper portion of the gear is retained by a retaining portion to cause the valve element to be spaced apart from the valve seat. After natural cooling, the pinion is remotely operated by an electric motor to rotate the gear, thereby canceling the holding. A resilient arm causes the gear to be disengaged from the retaining portion by its urging force, brings the valve element into pressure contact with the valve seat, and allows the opening/closing operation to function smoothly.

  • Patent number: 6748967
    Abstract: Couplers for joining actuators to valves are configured to allow their affixment to different makes and models of actuators and valves, thereby allowing an off-the-shelf S coupling solution and avoiding the need to specially construct a coupler which is only adapted to connect whatever valve and actuator that are desired for coupling. The couplers include a shaft/stem bore which accommodates the torque-transmitting components of the valve and actuator to be coupled, and sets of affixment holes surround the shaft/stem bore, with these affixment holes being arrayed in patterns matching those of different common valves and actuators. Thus, a coupler may affix to different valves or actuators provided the appropriate affixment holes are chosen. The couplers may be formed as single-piece or multi-piece units.

  • Patent number: 6186164
    Abstract: A rotary valve includes a housing having a housing bore which can be laterally closed by bearing covers. Inside the housing, a cellular wheel is rotatably supported. A guiding device extends in an axial direction of the cellular wheel and serves for drawing the cellular wheel in the direction of its axis of rotation out of the housing bore. This guiding device includes an additional bearing which can be displaceable in the axial direction relative to that bearing cover which is on the guiding side. The additional bearing serves to support the cellular wheel temporarily during removal from the housing bore. This additional bearing can be connected to that end of a cellular wheel shaft which is situated at the side of the guiding device.
