Definitions
- the invention relates to a magazine for caseless propellant charges with a strip-shaped carrier having recesses for the propellant charges.
- propellant charges are ignited in the magazine itself. Under certain circumstances, this can lead to the neighboring propellant charge being ignited simultaneously. According to a further design, it is known to push the propellant charge out of the magazine and into a combustion chamber for ignition. Ignitions of the adjacent propellant charges can thereby be avoided.
- the mechanical loading of the propellant charges during the pushing in and pushing out. This problem occurs in particular when the propellant charge is pushed out of the magazine several times and returned to the magazine. Another problem is the sealing of the combustion chamber.
- the invention is therefore based on the object of providing a device for protecting the propellant charges and for sealing the combustion chamber.
- this object is achieved in that receptacles for the propellant charges are arranged within the recesses, which have an inwardly projecting sealing bead on one end face and are connected to the carrier via predetermined breaking points.
- the mechanical stress on the propellant charges is avoided by the recordings.
- the propellant charges can thus be transported from the magazine into the combustion chamber and back into the magazine practically as often as required without being damaged. There is no wear on the caseless propellant charges.
- a sealing bead protruding inwards on one end face is acted upon by the propellant gases generated during the ignition of a propellant charge and is thereby pressed in the axial direction against the component delimiting the combustion chamber, a good seal being achieved.
- Another sealing effect is the radial expandability of the receptacle.
- the sealing bead is advantageously connected in one piece to the receptacle.
- propellant charges in the receptacle are inside the recesses and do not protrude above the carrier, they are completely protected. This also means a significant improvement in the storage and transportation of the caseless propellant charges.
- the receptacles can have any shape, but in practice it has proven to be expedient for the receptacles to be sleeve-shaped.
- the recordings surround the propellant charge on its entire circumference. This largely prevents damage to the caseless propellant charges. Occasionally it happens that a propellant charge is not or only partially ignited. In this case, the sleeve-shaped receptacle brings the remnants of the propellant charge back into the magazine. This prevents contamination of the combustion chamber.
- the recordings can be connected to the carrier in various ways. However, it has proven to be expedient that the predetermined breaking points are designed as dividers. Pushing the recordings out of the carrier thus requires a determinable force. If this is exceeded, the receptacle together with the propellant charge contained therein can be pressed out of the carrier.
- any number of dividers can be provided.
- the device shown in FIG. 1 consists of a housing 1 and a handle 2 arranged on the side of it.
- the handle 2 has a trigger 3.
- a barrel designated 4 overall is axially displaceably mounted.
- a driving piston 5 is guided in the barrel 4.
- the rear end of the barrel 4 is designed as a feed member 4a.
- the feed member 4a protrudes through an opening of a magazine, designated overall by 6.
- the magazine 6 contains recesses 6a in recesses.
- the receptacles 6a are sleeve-shaped and contain a sleeveless propellant charge 7.
- a propellant charge 7 When the device is pressed, a propellant charge 7 together with a receptacle 6a surrounding it is pushed out of the magazine 6 and into a combustion chamber 8 by the feed member 4a.
- the propellant charge 7 is ignited in the combustion chamber 8 by means of an ignition device which is known per se and is not shown in detail.
- the propellant gases generated when the propellant charge 7 is ignited pass through a feed channel 4b into a working space 4c, where they act on the rear side of the driving piston 5.
- the receptacle 6a has a sealing bead 6c at its end adjacent to the feed element 4a.
- the sealing bead 6c is caused by the propellant gases pressed against the feed member 4a and thus enables a good seal of the feed member 4a.
- the receptacle 6a is returned to the magazine 6 by a plunger 9. Any residues of the propellant charge 7 are also returned to the magazine 6.
- the receptacles 6a are clearly visible.
- the figure also shows the sealing bead 6c.
- the lower receptacle 6a contains a sleeveless propellant charge 7.
- the figure further shows a separating web 6b, with which the receptacle 6a is connected to a carrier 6d.
- FIG. 3 shows a view of the magazine 6 shown in FIG. 2.
- the strip-shaped carrier 6d is also clearly visible.
- the carrier 6d contains receptacles 6a in receiving openings.
- the receptacles 6a are connected to the carrier 6d via dividers 6b. When a receptacle 6a is pressed out, the separating webs 6b are severed. As the figure shows, three dividers 6b are provided. These allow the receptacles 6a to be centered and provide a sufficient hold for the receptacles 6a conveyed back into the magazine.
