  • Fixed lever and pin assembly for stabilizing gas flow and pressure regulation of a fluid regulator
    Patent number: 10316987
    Abstract: A fixed lever and pin assembly may include a lever body having a front end, a back end, and an arm connecting the front end and the back end. The front end of the lever body may be operatively coupled to a control element of a regulator. The arm may be adapted to operatively couple to an actuator of a regulator. A pin may be fixed to the front end of the lever body and may be disposed through the front end in a direction perpendicular to first and second parallel sides of the lever body. The fixed lever and pin assembly may be an integrated piece and the pin may prevent the lever body from moving independently from the pin.
