Definitions

  • This invention relates to ordnance and particularly to recoil and counter-recoil or running-out gear for guns.
  • the invention relates type these pressures are communicated to all parts,
  • This invention has vfor one of its objects to provide a hydro-pneumatic recoil and counter-- recoil system and mechanism so designed as to confine the high pressures to the recoil cylinder and to prevent the communication of such high pressures to other parts of the mechanism and system.
  • Another object of the invention is to provide mechanism of the character described so constructed and arranged as to obtain a positive control of the counter-recoil andV furthermore a con-V struction in which the recoil and counter-recoil actions are positive and Vindependent of the amount of ⁇ fluid in therecuperator or of the particular position of the floatingpiston therein.
  • Another object of the invention is to provide simple, practical and effective recoil and counterreccilfmechanism so constructed and arranged as to operate Yefficiently and furthermore so constructed and arranged that the hydraulic and pneumatic fluids are conned in the system and are merely shifted or displaced from one part of the system to another during Vthe recoil and counter-recoil actions.

  • Y 3 I. L The invention briefly described consists of a system and mechanism comprising a recoilcylinder, a counter-recoil cylinder, a recuperator cylinder and conduits and valve controlled passages between these parts so constructed and arranged that when the gun is red the liquid ⁇ will be trans-- ferred to a large extent from the recoil cylinder into the recuperatorrcylinder causing gas under elevation of.

  • An enlargement of the end of the counterrecoil cylinder forms a hollow piston 23 which ⁇ fits in the recoil cylinder.
  • a perforated disk 24 In the end of this piston is a perforated disk 24. 25 is a valve within this hollow piston pressed against a seat 25 by a spring 21 interposed between the disk 24 and an interrupted shoulder 28 on the valve.
  • the recoil and counter-recoil cylinders are filled with oil or other suitable liquid and this valve permits the oil to flow from the counter-recoil cylinder into the recoil cylinder through the disk 24, but checks its ow in the opposite direction.
  • the recoil cylinder I5 is provided with longitudinally extending internal grooves 33 which are tapered longitudinally either in Width or in depth.
  • the counter-recoil cylinder I8 is also provided with similar longitudinally extending grooves 34 tapered in a like manner.

  • a perforated disc 31 is disposed between the valve chamber 35 and the cylinder II and a spring 38 seats against the disc 31 and normally forces a check valve 39 upwardly against a seat 40.
  • the valve chamber 35 also communicates with a Conduit 4I which is fixed in the yokes and has a curvedend 42 connected to the head of the recoil cylinder I5 and communicating with the hollow piston rod 30.

  • the initial pressure of the gas in the recoil cylinder is predetermined by the requirements of the. system and may be approximately 1500 pounds. It will be understood, however, that this pressure will be varied according to the conditions encountered. Sufiicient pressure is used to overbalance the gun barrel and the parts movable therewith and to return them to battery position after firing, even when raised to high elevations.
