Abstract
A specialized recoil absorber mounted to a gun dampens and absorbs the recoil force of a gun during the firing thereof. The recoil absorber includes a closed, fluid filled cylinder having a first end and a second end. A piston closely fits within the cylinder and slides therein along the cylinders longitudinal axis and a spring is compressed between the piston and the first end. The cylinder defines channels at an outer diametrical surface thereof, the channels having a helical twist centered on the longitudinal axis, whereby the piston rotates as it translates.
Claims11
A device mounted to a gun for dampening and absorbing the recoil of the gun during the firing thereof, comprising:
- means for mounting the device to the gun;
- a cylinder having a first end and a second end;
- liquid in the cylinder;
- a longitudinal axis of the cylinder;
- a piston in the cylinder axially sliding therein;
- a spring between the piston and the first end;
- the piston defining a channel having a helical twist relative to the longitudinal axis;
- adjustment means for varying a rate of piston rotation for a given spring force.
