Definitions
- the invention relates to a cooling device for revolver drums from Revolver cannons, according to the preamble of claim 1.
- the patent cited above proposes to provide cooling channels in the region of the end part of the weapon barrel axially adjacent to a drum in the drum, radially outward, between the individual cartridge chambers, which have a main channel for the coolant supply running in the drum axis are connected.
- the cooling channels are connected to nozzles running parallel to the drum axis, which open into the end of the drum facing the weapon barrel and are arranged at the same distance from the longitudinal axis of the drum as the central longitudinal axes of the cartridge chamber.
- Shut-off devices for the nozzles are provided in the cooling channels, which in the event of bombardment briefly release the nozzle in the area of the pipe opening.
- the shut-off devices are, for example, slides which can be moved by means of control pieces sliding along a control cam when the drum rotates.
- the coolant passes through the nozzles directly onto the inner wall of the weapon barrel in the rear part.
- the nozzles are only open for the period when the nozzles slide past in the rear of the gun barrel and the coolant is only supplied when shooting.
- the coolant in the above-described cooling device for one Gun barrel is passed through the drum, can only be a cooling in Area of the drum front wall can be reached, so that this device for the Eliminating the problems mentioned above is not suitable.
- US-A-2,801,575 (see the preamble of claim 1) describes a revolver barrel of a firearm with a cooling device; In the circumferential direction, alternating cooling channels follow in parallel to the drum axis and are connected to one another at their ends and along their length at a multiplicity of locations, which extend over the length of the bullet guide of the cartridge chamber, so that each cartridge chamber lies between two cooling channels and experiences a cooling effect from both . Conversely, each cooling channel is arranged between two cartridge chambers and must therefore contribute to the cooling of two cartridge chambers, so that a sufficient cooling effect per cartridge chamber is not guaranteed, although the construction is relatively complex due to the large number of connecting channels.
- each cartridge chamber is two Assigned cooling channels, but, in contrast to the device according to this patent specification, both cooling channels are only responsible for cooling a single cartridge chamber.
- the first of two cooling channels assigned to a cartridge chamber In the area of one end of the revolver drum stands the first of two cooling channels assigned to a cartridge chamber first tangential connecting pipes and the radial input channels with the one in the Inflow channel provided in the drum axis in connection.
- the second of each two cooling channels assigned to a cartridge chamber is also in the area of an end face of the revolver drum via second tangential connecting pipes and radial output channels running parallel to the input channels with an in connected to the drain axis provided drain channel.
- the advantages achieved by the invention are, in particular, that the coolant is not passed through all the cooling channels of the revolver drum one after the other, but that each cartridge chamber is assigned its own cooling circuit, with the result that effective, rapidly dissipating cooling is achieved.
- Another advantage can be seen in the fact that a substantial part of the heat is quickly dissipated in the most heated area, in which the projectile is guided in the cartridge chamber. As a result, the area of the revolver drum in which the sleeve is guided in the cartridge chamber can no longer heat up as much. With these measures, the impairment of the cannon functions and strength problems are avoided and the tension curve in the drum is improved. Further advantages can be seen in the low manufacturing and logistics costs as well as in the small change effort for existing cannons.
- 1 to 4 , 1 denotes a revolver drum which is rotatably mounted on a drum axis 2 .
- the revolver drum 1 has 4 cartridge chambers 3 , which are divided into a projectile guide 3.1 and a sleeve guide 3.2 .
- Each cartridge chamber 3 are associated with two extending parallel to the drum axis 2 cooling channels 4, which extend over the whole length of the floor guides 3.1 of the cartridge chamber 3 and are arranged in the region between the respective Patroneniager 3 and the periphery of the revolving drum.
- the cooling channels 4 are closed on one end face 5 of the revolver drum 1 by means of sealing plugs 6 .
- the cooling channels 4 assigned to a specific cartridge chamber 3 are connected to one another via tangentially extending connecting channels 7 .
- the openings of the connecting channels 7 open into recesses 8 of the revolver drum 1 and are closed with further sealing plugs 9 .
- In the region of one end face 5 of the revolving drum 1 is respectively connected to deflecting parts 11 of the first of two a cartridge chamber 3 associated cooling channels 4 extending through first tangential connecting pipes 10th
- the deflecting parts 11 are connected to an inlet channel 13 provided in the drum axis 2 via radial inlet channels 12 which are offset by an angle of 90 ° to one another and arranged between the cartridge bearings 3 .
- the inflow channel 13 there are four radial bores 14 offset from one another by an angle of 90 ° in the drum axis 2 , the axes of which lie in the same plane perpendicular to the drum axis 2 as the axes of the input channels 12 .
- the deflecting parts 11 of the second of two a cartridge chamber 3 associated cooling channels 4 extending via second tangential connecting pipes 15 °.
- the deflecting parts 11 are connected to an outlet channel 17 provided in the drum axis 2 via outlet channels 16 which run radially and parallel to the inlet channels 12 .
- the outflow channel 17 is separated from the inflow channel 13 by an intermediate piece 18 .
- At the beginning of the discharge channel 17 there are four radial bores 19 offset from one another by an angle of 90 ° in the drum axis 2 , the axes of which lie in the same plane directed perpendicular to the drum axis 2 as the axes of the output channels 16 .
- 20 denotes a sealing sleeve in which sealing rings 21 resting on the drum axis 2 are held so that a coolant located in the cooling channels cannot escape.
- the cooling device described above works as follows: The coolant is supplied via the inflow channel 13 , the four bores 14 , the four input channels 12 and the four first connecting pipes 10 to all the first cooling channels 4 ( 4 ′, FIG. 3 ) of the cartridge chamber 3 and from all second cooling channels 4 ( 4 ", 3 ) the cartridge chamber 3 is simultaneously removed again via the four second connecting pipes 15 , the four outlet channels 16 , the four bores 19 and the discharge channel 17. In this way, each cartridge chamber 3 is cooled separately and simultaneously with the others, so that a rapid and effective cooling is achieved.
- the cooling can be operated by means of an open or closed circuit, water being used as the coolant, for example, and a pump provided for the coolant circulation being able to be switched on or off depending on the drum temperature. It is also irrelevant whether the cooling channels 4 through which the coolant flows through the described input channels 12 to the output channels 16 or vice versa.
