ABSTRACT:
A recoil system for field-type guns automatically adjusts the recoil distance of the barrel according to the angle of elevation of the gun barrel relative to the ground. The system includes a recoil cylinder in fixed relationship to the gun barrel and a piston rod operably connected to a two-art piston valve within the cylinder. The rotational position of one of the valve parts is controlled by the angular position of the piston rod about its axis and the rotation position of the second valve part is controlled by its axial piston within the recoil cylinder bore. Fluid flow orifi are defined between the first and second valve part, the area of the orifi being determined by the rotational positions of the two valve parts relative to each other. As barrel elevation is increased, the piston rod is rotated via a camming device which is itself moved by a tooth riding in a non-axial and non-linear slot in the camming device. The higher the barrel elevation, the smaller the orifi area defined between the two valve parts and the shorter the recoil distance allowed before fluid flow is terminated and barrel recoil arrested.
