Abstract
A device and system for metering the flow of gas into a gas driven reloading system of a firearm, the device is a gas plate that includes a plurality of openings of differing radii, a plurality of positioning notches formed on an edge of the gas plate, and a series of teeth formed on a surface of the gas plate, where the series of teeth are formed with a pitch configured to correspond with threads of a worm drive, and where at least a partial rotation of the worm drive slidingly positions the gas plate with respect to the adjustable gas regulator. The system includes the device and the adjustable gas regulator having a body configured to receive the device and the worm drive.
Claims16
A gas plate for an adjustable gas regulator, the gas plate comprising:
- a plurality of openings of differing radii;
- a positioning ball biased by a spring plate, where the spring plate is coupled to an exterior surface of the adjustable gas regulator;
- a plurality of positioning notches formed on an edge of the gas plate, where each of the plurality of positioning notches is formed with a semi-circular shape and configured to engage the positioning ball;
- and
- a series of teeth formed on a surface of the gas plate, where the series of teeth are formed with a pitch configured to correspond with threads of a worm drive, and where at least a partial rotation of the worm drive slidingly positions the gas plate with respect to the adjustable gas regulator.
An adjustable gas regulator comprising:
- a body having an opening configured to receive a movable gas plate and a worm drive;
- where the gas plate comprises a plurality of openings of differing radii, a positioning ball biased by a spring plate, where the spring plate is coupled to an exterior surface of the adjustable gas regulator, a plurality of positioning notches formed on an edge of the gas plate, where each of the plurality of positioning notches is formed with a semi-circular shape and configured to engage the positioning ball, and a series of teeth formed on a surface adjacent the plurality of openings;
- and
- where the worm drive is configured to engage the series of teeth and adjust the position of the gas plate in response to at least a partial rotation of the worm drive.
A rifle with a gas driven reloading system, the rifle comprising:
- an elongated barrel having a bore through which a round of ammunition passes, where the barrel includes a gas port that exhausts gas into the reloading system;
- and
- an adjustable gas regulator for metering the flow of the gas into the reloading system, the adjustable gas regulator comprising:
- a body having an opening configured to receive a movable gas plate and a worm drive;
- where the gas plate comprises a plurality of openings of differing radii, a positioning ball biased by a spring plate, where the spring plate is coupled to an exterior surface of the adjustable gas regulator, a plurality of positioning notches formed on an edge of the gas plate, where each of the plurality of positioning notches is formed with a semi-circular shape and configured to engage the positioning ball, and a series of teeth formed on a surface adjacent the plurality of openings;
- and
- where the worm drive is configured to engage the series of teeth and adjust the position of the gas plate in response to at least a partial rotation of the worm drive.
