Definitions

  • One of the cylinders partly [58] Field of Search ..89/43, 177, 178 ff th o nter-re oil and the other of the cylinders includes means for feeding separately and storing a part of the I References Cited energy required for the counter-recoil stroke of the barrel.
  • the present invention relates to pneumatic counterrecoil mechanism for guns.
  • Such pneumatic counterrecoil mechanism comprises mostly a pneumatic cylinder, which is immovably disposed in relation to the gun barrel and the piston rod of which is coupled with the gun barrel.
  • the energy required for the following recoil is storedin a pressure chamber of the counterrecoil cylinder.
  • This stored energy must be in position to return the barrel into its forwardmost position and under circumstances to operate auxiliary loading devices and the breech block.
  • the shell energy, from which, in the last resort, all required energy is taken, must be thus so great, that the barrel performs a predetermined minimum recoil travel and by overcoming the most different resistances, as for instance, the force from the weight component of the barrel raised during firing, the barrel must be counterrecoiled into its original position.
  • the recoil energy can become transmitted to the gun barrel exhausted before reaching.
  • the required minimum recoil travel by the brake cylinder, and also the storage of the counterrecoil energy can be consumated, so that functional disturbances can be encountered.
  • lt is one object of the present invention to provide a pneumatic counterrecoil mechanism for guns which, with great charges as well as with small charges and a required minimum recoil travel, still contains sufficient energy, in order to return the barrel again into its forwardmost original position.
  • the additional energy portion required for the counterrecoil can be fed by different means and in particular, for instance, by means of a manually operated pump and pressurized oil or by means of nitrogen from a nitrogen pressure bottle or in vehicles by means of a hydraulic arrangement available in the vehicle.
  • the piston rod of the second cylinder is not rigidlyconnected with a driver of the gun barrel, rather it is displaceably guided in the latter and equipped at its rear end with a driver abutment.
  • the displacement of the piston in the second cylinder can take place, in an advantageous embodiment of the present invention, by applying a pressure medium at its forward side, whereby the piston in its new position is settable by a control valve provided in the feed or conduit for the pressure medium, against the gas pressure present in a pressure chamber of the second cylinder.
  • a control valve provided in the feed or conduit for the pressure medium, against the gas pressure present in a pressure chamber of the second cylinder.
  • the counterrecoil mechanism comprises substantially two counterrecoil cylinders l and 2. Both cylinders l and 2 are secured to a cradle 3.
  • the piston 8 In the cylinder 1, which receives a piston 8 with its piston rod 9, the piston 8 is reciprocably arranged and in the cylinder Z-the piston 11 reciprocates with its piston rod 12.
  • the pistonrod 9 of the cylinder 1 is rigidly connected by means of nuts 7 and 25 on a driver 4 connected with the breech 5. of the gun barrel 6, the piston rod 12 of the second cylinder is displaceable in the driver 4 and has at its rear end a driver abutment (nut) 24.
  • both cylinders arepartly effective for storing the counterrecoil energy, by joining both piston rods for joint travel with the recoiling' gun barrel. Thereby the gas fillings present in the pressure and storage chambers 10 and 17, respectively, are compressed.
  • the piston 11 Priorto firing with a small charge, the resistance of the second cylinder is eliminated.
  • the piston 11 is charged at its front side by means of a manually operated pump .15 by means of a conduit 22 and a pressure chamber 18 with pressurized oil.
  • the piston is displaced thereby for the minimum recoil travel X and the gas filling is stored in the storage chamber 17.
  • This position of the piston 11 is retained by a back pressure valve 19.
  • a switching cam20 disposed displaceable and securable at the gun barrel, operates-a switch 21, with which a control valve 16 provided in the conduit 22 is switched over.
  • the switching cam 20 is likewise disposed spaced apartfrom the switch 21 for the distance x, so that the abutment24on the driver 4 comes into engagement again.
  • the compressed gas fillings in the storage chambers 10 and 17 cause now jointly the counterrecoil of the gun barrel.
  • the piston f the cylinder 1 is likewise capable of being charged with pressurized oil at its front :side.
  • the piston 8 can be charged via the conduit 28 and displaced rearwardly, whereby the piston rod9moves the gun barrel into its rearward position.
  • Adischarge valve 26 is provided, which upon opening permits the release of the pressurized oil from the conduits 28 into the oil container 14. The stored gas filling in both pressurized chambers 10 and 17 causes thereafter the counterrecoil of the gun barrel.
