摘要： A recoil system for field-type gun is described for controlling the recoil distance of a gun barrel according to angle of elevation of the barrel, the barrel having breech means at one end and a muzzle at the other end, the barrel being movably supported during recoil travel on a cradle adjacent its breech end by curvilinear track means and by bearing means intermediate the breech means and the muzzle, the cradle being supported on carriage means such that the angle of elevation of the barrel may be changed; the recoil system comprising a recoil cylinder in fixed relationship to the barrel and movable therewith; valve means within said recoil cylinder, said valve means being adjustable so as to vary the area of an orifice through which a fluid is forced under recoil conditions; one end of a piston rod operably connected to said valve means so as to cause fluid to pass through said orifice under recoil travel; the remote end of said piston rod being maintained in a substantially axially stationary position relative to said cradle; said piston rod being controllably rotatable about its axis; part of said piston rod being situated outside said recoil cylinder and being operably connected to camming means for controlling the rotational position of the piston rod and hence said valve means orifice area; said camming means having its position determined by control means connected to the cradle, said control means being positionally responsive in the axial direction,
relative to said cradle, to barrel elevation and prevent movement of said camming means during recoil movement; and means associated with said recoil cylinder to further control the area of said orifice in response to recoil distance.
