Definitions

  • the invention relates to a hydraulic weapon barrel brake with a pneumatic barrel retractor that can be moved jointly over the base piece of a weapon barrel according to the preamble of patent claim 1.
  • the tube recoiler only consists of a cylinder and a piston rod with piston and the associated seals. With the same predeterminable total volume of the pipe recoiler, a large gas volume with the advantages of a flat compression line is available, particularly with regard to the stability of the seals.
  • the means for pre-damping take effect at the same time by opening at least one bore arranged in the piston ring and running axially parallel with a constant throttle cross-section.
  • additional throttling devices for the barrel advance in the barrel retractor can be dispensed with.
  • the constant throttle cross-section ensures that the speed can be predetermined to be uniform, as required by the mechanical mechanical operating conditions of the weapon.
  • the movements of the piston ring acting as a gate valve are limited on one side by a piston head detachably connected to a brake piston.
  • the releasability of the piston head ensures easy assembly of the piston ring on the brake piston.
  • control rod is equipped with throttle grooves of different lengths, whereby only throttle grooves of the same length can be blocked or released by the piston ring.
  • the pipe brake 1 is connected to its brake piston rod 48 on the base piece 2 via fastening means 62, not described.
  • the tube feeder 3 is connected via a piston rod 25 to the base piece 2 by means of fastening means 63, which are also not described in detail.
  • the respective cylinders of the tube brake 1 and the tube feeder 3 are arranged on a cradle roller, not shown, preferably diametrically opposite one another.
  • the tube recoiler 3 comprises a cylinder 24 with a graduated diameter, which consists of prefabricated, preferably smooth tubes on the inside, so that an additional aftertreatment can largely be dispensed with.
  • the cylinder 24 of the tube recoiler 3 can also consist of a single tube of the same diameter.
  • a piston 26 is slidably arranged within the cylinder 24 of the tube recoiler 3.
  • the compressed gas at the gun barrel return is comparatively only slightly compressed, so that the pressure increase compared to known barrel recoilers is minimal, which, for example, the load on the piston 26 and on Cylinder 24 existing sealing elements 28, 29 is low.
  • the cylinder 24 is closed on both sides by known flanges 30, 31, the flange 30 assigned to the base piece 2 containing guide and further sealing means 32, 33 and the other flange 31 containing a ventilation hole 34.
  • the pipe brake 1 shown in FIGS. 1 to 4 is also closed on both sides of its cylinder jacket 35 by flanges 36, 37, the flange 36 arranged on the bottom part being equipped in a known manner with means for guiding and sealing the brake piston rod 48 connected to the brake piston 4, while the flange 37 attached to the other end of the jacket 35 is a support bearing for a spring 38 of one described in DE-PS 12 83 706
  • Compensating piston 39 and a guide of a position 40 of the compensating piston 39 indicating the outside are essentially known and not relevant to the invention, so that a detailed description is unnecessary.
  • a liquid flow control rod 5 rigidly attached to the cylinder jacket 35 in front of the compensating piston 39.
  • This control rod 5 is designed in the area of its attachment as a disk 41, as a result of which the space present between the compensating piston 39 and the flange 36 arranged on the base piece side is divided into a heat compensation chamber 42 and a brake chamber 13. Both rooms 13, 42 are connected to one another via at least one known compensation bore 43.
  • the disk 41 is connected on the side of the heat compensation chamber 42 via a flange 45 which can be screwed on by means of screws 44, through which three segments 47, which are distributed over the circumference and engage positively in recesses 46 of the cylinder jacket, provide a solid fastening of the control rod 5 form on the cylinder wall 35.
  • the segments 47 ensure simple assembly and disassembly of the control rod 5.
  • the control rod 5 with its part projecting into the brake piston 4 and the brake piston rod 48, forms a throttle chamber 14 known per se for throttling the return movement of the weapon barrel.
  • the control rod 5 contains, in a further known manner, a feed inhibitor mandrel 49 which, for returning the pressure fluid, has a longitudinal groove (not shown) which opens into a feed inhibitor mandrel chamber 51.
  • the control rod 5 is provided with an axial bore 52, which is connected on the one hand via further bores 53 to the hydraulic brake mandrel chamber 51 and on the other hand directly in front of the disk 41 via radial bores 54 with the brake chamber 13.
  • the outlet of the axial bore 52 is closed with a stopper 55.
  • the brake piston 4 of the pipe brake 1 contains as a means for pipe return and flow damping against the force of a spring 6 axially displaceable piston ring 7, which is designed as a gate valve and under the force of the spring 6 on the gun barrel advance on the one hand that in the brake piston 4 between one of the brake pistons 4 or the brake piston rod 48 and the brake cylinder inner surface 10 formed brake chamber 13 and a jointly formed by the brake piston 4 or the brake piston rod 48 and the control rod arranged throttle chamber 14 connecting channels 12 and on the other hand at least one arranged within the piston ring 7 bore 15 as a means for a targeted flow damping can be effective.
  • the bores 15 run axially parallel within the piston ring 7 and, during the advance of the weapon barrel, connect the brake chamber 13 behind their free outputs 16 to the space 56 formed between the piston ring 7 and the disk 41 of the control rod 5.
  • the diameter d and the length 1 of each bore 15 are chosen so that the forward speed of the weapon barrel attached to the base piece 2 can be predetermined and takes an approximately constant course.
  • the piston ring 7 On the side facing away from the outlets 16, the piston ring 7 contains an end face which is adapted to a preferably radially extending stop face 18 of the brake piston 4 17, into which the holes 15 open.
  • Figure 3 illustrates the position of the ring piston during the barrel return.
  • the brake piston rod 48 is pulled through the base piece 2 in the direction 57 out of the pipe brake 1.
  • the pressure fluid flows in the direction of the arrows from the pressure chamber 13 via the connecting channels 12 of the brake piston 4 into the pressure chamber 14 and from there into the chamber 56, the gun barrel return being braked in a known manner in accordance with the throttle cross sections of the control rod 5.
  • FIG. 4 shows the movement process during the pipe advance, the piston rod 25 being drawn into the pipe recoiler 3 by the piston 26 by the expanding compressed gas, so that the brake piston rod 48 is also moved into the cylinder 35 of the pipe brake 1 via the moving base piece 2.
  • the piston ring 7 has moved axially under the force of the spring 6 into the closed position of the connecting channels 12 which is delimited by a stop 59 provided on the brake piston 4 (FIG. 2).
  • the hydraulic fluid therefore no longer flows through the connecting channels 12 when the weapon barrel is advancing in the direction of the arrow indicated, but to achieve a predetermined one
  • the piston ring 7 is equipped with low-friction and low-maintenance sealing elements 9, 9.1 for sealing and for achieving a rapid sliding movement on its outer surface 8 facing the inner surface 10 of the cylinder jacket 35.
  • the inside of the piston ring 7 slides with its guide surface 11 designed as a bore on a cylindrical shoulder 60 of the brake piston 4.
  • a head 19 receiving the stop surface 18 of the brake piston 4 is detachably fastened by a thread 61 to the free end of the brake piston 4.
  • the thread 61 has a smaller diameter than the projection 60.
  • the spring 6 arranged between the end face 16 of the piston ring 7 and the stop face 18 of the head 19 is designed as a compression spring and is mounted in respective grooves 20, 21 of the piston head 19 and the piston ring 7 pointing in the axial directions.
  • the connecting channels 12 arranged and lockable by the piston ring 7 inside the brake piston 4 open into throttle grooves 22, 23 of the control rod 51, the throttle grooves 22, 23 having a different length and are adjustable outside the pipe brake 1 in a manner not shown.
  • the maximum return path of the weapon barrel indicated by s in FIG. 1 can be achieved by comparatively long throttle grooves 23 and a shortened return path by shorter throttle grooves 22.
  • the Throttle grooves 22, 23 are staggered relative to the connecting channels 12 such that only opposite, equally long throttle grooves 22 or 23 can be connected to the connecting channels 12.
  • the throttle rod is fastened here differently from the example shown in FIG. 2 outside the pipe brake 1.
