Abstract
A suppressor has an outer shell with a bore defined along a central longitudinal axis of the shell and fluidically coupling an entrance port to an exit port. Baffles enclosed within the outer shell each have a central aperture circumvolving the bore and a deflecting channel radially offset from the bore and in fluid communication with the central aperture. Each deflecting channel is formed by opposing sidewalls formed in a baffle and extending to a diversion wall. First and second openings of a deflecting channel fluidically couple the channel with the bore and with the volume enclosed by the outer shell. Each deflecting channel deflects propellant gases in a direction perpendicular to axial flow through the bore.
Claims20
A fluid pressure dampener, comprising:
- an outer shell enclosing a volume and having an entrance port and an exit port;
- a bore defined through the outer shell and fluidically connecting the entrance port and the exit port, the bore defining a longitudinal axis of the dampener;
- one or more baffles enclosed within the outer shell, each of the one or more baffles having a central aperture circumvolving the bore and a deflecting channel formed in the baffle and radially offset from the bore, the deflecting channel having a first opening, a second opening, a diversion wall extending between the first opening and the second opening, and opposing sidewalls extending from the central aperture to the diversion wall, wherein the first opening is in fluid communication with the enclosed volume and the second opening is in fluid communication with the bore defined through that baffle.
A baffle for a fluid pressure dampener, comprising:
- a flange surface;
- a body extending from the flange surface, the body having a central aperture defining a flow axis;
- and
- a deflecting channel formed in the body and in fluid communication with the central aperture, the deflecting channel offset from the flow axis and having a first opening, a second opening, a diversion wall extending between the first opening and the second opening, and opposing sidewalls extending from the central aperture to the diversion wall.
