  • Patent number: 8226312
    Abstract: A valve door for a seal cylinder comprises a lid having first and second surfaces and a connecting means connecting the lid with an actuating mechanism, the connecting means distributes forces from the actuating mechanism across a portion of the first lid surface in order to bias the lid to a closed position. A force directing member is attached to the first lid surface, the force directing member being adapted to distribute force from the connecting means over a portion of the lid surface, thereby maintaining a positive seal and reducing lid deflection.
    Type: Grant

  • Patent number: 8221012
    Abstract: An instrument includes an instrument body having an opening at one end. A valve is mounted within the instrument body, the valve having an opening at one end. A lid is integrally molded with the valve and hingedly movable with respect to the valve opening. An actuating arm is operatively connected to the lid, the actuating arm transmitting forces from an instrument movement mechanism to the valve door under both tension and compression. As a result, the lid is opened and closed substantially solely by the actuating arm.
