Abstract
Recoil buffers are described that can complete a displacement cycle in about 0.06 seconds or less. The buffer can include two springs and three one-way valves through the piston within the buffer housing or can include a single spring and a one-way shim valve through the piston within the buffer housing.
Claims13
A buffer for a gun mount, comprising:
- a buffer housing having an internal chamber;
- a piston shaft configured to move into and out of the housing;
- a piston having a first end fixed on a first end of the piston shaft;
- one or more passages extending between the first end and a second end of the piston;
- a plurality of raised structures extending from the second end of the piston;
- a plate disposed on the second end of the piston and having a plurality of grooves that each mate with one of the plurality of raised structures to allow even movement of the plate relative to the piston, the plate configured to open and close the one or more passages;
- and,
- a spring positioned against the plurality of raised structures on the second end of the piston, in front of the plate, and against a side of the internal chamber of the buffer housing such that the plate is movable between the piston and the spring.

- a piston having a first end fixed on a first end of the piston shaft;
- one or more passages extending between the first end and a second end of the piston;
- a plurality of raised structures located on the second end of the piston;
- a plate disposed on the second end of the piston and having a plurality of cut-away areas that each are each positioned at least partially around one of the plurality of raised structures to facilitate even movement of the plate relative to the piston, the plate configured to open and close the one or more passages;
- and,
- a spring positioned against the plurality of raised structures on the second end of the piston, in front of the plate, and against a side of the internal chamber of the buffer housing such that the plate is movable between the piston and the spring.
