Definitions

  • the invention relates to a pneumatic balancer for guns with a balancer cylinder, the cylinder space takes out an extendable control rod and is filled with a gas.
  • Such compensators for example known from the "Weapons-technical paperback" Rheinmetall, 6th edition 1983 page 356, picture 890, are used in guns to cancel the front load of the height adjustment part as possible, so that the focus of the height adjustment part lies in the height adjustment axis, the shield pin axis.
  • the balancer is placed between the top mount and the cradle of the gun.
  • the front load creates a torque equal to the weight multiplied by its distance from the gun's trunnion axis. This is countered by a compensating torque equal to the compensating force multiplied by its distance from the shield pin axis of the same size, so that easy and uniform straightening is possible.
  • Pneumatic compensators have the disadvantage that they are sensitive to temperature. In order to achieve a better temperature adjustment, it is known to change the equalizer volume. This is done by moving the rear suspension point of the compensating cylinder. This displacement is carried out by a spindle which moves the rear articulation point along a straight line inclined at a small angle to the vertical. However, this temperature adjustment is not satisfactory. In particular at low temperatures there is a considerable deterioration in the moment compensation, while an improvement is only evident at temperatures above approximately + 20 ° C.
  • the object of the invention is therefore to provide a compensator of the type mentioned which is practically independent of temperature.
  • This object is achieved in that the cylinder space is connected to a device which compensates for the temperature-related pressure change of the gas in the cylinder space.
  • the temperature-related change in pressure is compensated according to the invention, ie gas is added or removed in accordance with the change in temperature, so that the compensator behaves in the same way as it does for p o and T o (normal temperature). In this way you get a moment compensation over the entire temperature range.
  • the compensator shown has a compensating cylinder 1 which has a cylinder space 2 filled with a gas, in particular nitrogen, which has a constriction 3 in the central region.
  • a regulating rod 4 projects into the compensating cylinder 1 to the area of the constriction 3 while leaving a narrow gap 5.
  • the control rod 4 has a gas space 6 that is open to the cylinder space 2.
  • a bellows 7 is used to protect the part of the control rod 4 that protrudes from the cylinder 1 is provided, which is used to fill the compensator with gas.
  • a pressure regulator 9 which is connected to a gas source 10 and has a gas return line 11 returning to the gas source 10, is also connected to the gas supply connection 8.
  • the pressure regulator 9 supplies gas from the gas source 10 to the pressure compensation due to the pressure drop determined by the pressure regulator 9 of the cylinder chamber pressure present thereon, while it ensures that the gas to be discharged for pressure compensation is removed when the temperature rises above T o .
  • the gas to be discharged is fed back to the gas source 10 without loss via a feed pump 12 connected to the gas return line 11.
