  • Publication number: 20250067361
    Abstract: A slam-shut mechanism for operatively connecting a slam-shut control element of a fluid regulator with a controller for the control element. The mechanism includes a shaft and a cam carried by the shaft and having a cam surface adapted to be operatively connected to the slam-shut control element. The mechanism also includes a latching pin carried by the shaft, a latch, and a lever operably connected to the latch and adapted to be selectively engaged by the controller. When the controller engages the lever, the latch is movable from a first position, in which the latch securely retains the latching pin, such that the cam surface is arranged to retain the slam-shut control element in a fully open position, to a second position, in which the latching pin is released from the latch, thereby allowing the slam-shut control element to move from the fully open position to a closed position.

  • Patent number: 9593781
    Abstract: A cam assembly for use in a slam-shut safety valve includes a cam having an elongated first cam arm, and the cam is pivotable about a rotational axis. The cam assembly also includes a torsional spring having a pair of stationary outer arms and a pair of pivotable inner arms, wherein the pair of stationary inner arms is coupled to a portion of the first cam arm. The pair of inner arms is adapted to act on the first cam arm to bias the cam into a position that allows the cam to be relatched in a valve rearming process. The pair of inner arms is symmetrically disposed about the first cam arm to prevent lateral displacement of the cam.

  • Patent number: 9303779
    Abstract: A slam-shut safety device includes a valve body, a valve disc, a reset pin, a and a guide collar. The valve disc is shiftable between an open position spaced away from a valve seat, and a closed position seated against the valve seat. The reset pin operatively is coupled to the valve disc and shiftable between an untripped position placing the valve disc in the open position and a tripped position placing the valve disc in the closed position. The guide collar includes a hollow cylindrical portion slidably supported in a guide bore and extending at least partly over the reset pin at a location adjacent to the valve disc. The guide collar is shiftable between a retracted position and an extended position relative to the guide bore for providing added structural integrity and protecting the reset pin from bending forces.

  • Patent number: 9221545
    Abstract: Aircraft nacelle assemblies include a frame, a cowl coupled to the frame, and a biasing member (including a passive mechanism) coupled between the frame and the cowl. The cowl is configured to move between a closed position and an open position. The passive mechanism is configured to provide a biasing force to the cowl. When the cowl is in or near the closed position, the biasing force coupled with the weight of the cowl results in a first net force that urges the cowl away from the open position, and when the cowl is in or near the open position, the biasing force coupled with the weight of the cowl results in a second net force that urges the cowl away from the closed position.
