The invention relates to an electric battery for feeding electrical equipment in proximity fuses of projectiles, the battery arranged in a first room being a Number of plate-shaped electrodes with spaces in between and a container in a second space with an electrolyte, further means are present by which, if a large acceleration in the axial direction of the projectile, the container is broken, so that the electrolyte flow from the second to the first space and thus flow into the interstices can.

Such batteries are known. It has been suggested to use the rifling of the projectile around the electrolyte after the container has been broken into the spaces between to drive the electrodes. In the known devices, the battery consists of this a number of stacked, ring-shaped electrodes, wherein the container with the electrolyte is arranged in the central room. The wall of the container is under the action of the at Shooting occurring axial acceleration forces destroyed. The twist of the projectile arises as a result of the pulls and fields of the tube, and the twist, the electrolyte is driven outwards. With mortars, the barrel generally has no lines or fields, so that the projectile does not twist and the battery cannot be made effective in the manner described. The invention creates a battery that works well in these cases

will certainly not be in tension until a certain time after the projectile has been fired.

According to the invention, such a spatial arrangement is chosen in the battery that the electrolyte, after the container is broken, first spread over two or more other rooms becomes, from which he under the action of inertia or centrifugal force after at least two separate rooms in which the ίο electrodes are housed.

The container with the electrolyte is preferably housed in a space with at least communicating with a second room, which is adjacent to the former and in its front part the electrodes are housed. The two rooms are e.g. through canals. connected with each other.

The space in which the container is arranged can also be connected to a third space stand, which also contains electrodes and which lies in the axial direction in front of the space in which the the first-mentioned electrodes are housed. Preferably, however, a number are adjacent Spaces provided that are mutually and concentrically to the first and that ever contain a set of electrodes. Each of these electrodes containing spaces can with one be connected intermediate space, the intermediate spaces each having a part of the electrolyte be able to record. After the projectile has been fired, the electrolyte first fills the back the first space, whereupon, under the effect of the deceleration forces, it moves into the spaces in front of the spaces Electrode spaces flows. The spaces in between can have different contents, so that the parts the battery, which has to deliver the greatest current (e.g. heating current), larger quantities of electrolyte preserved than the other parts.

Batteries are already known in which, after the breakage of the electrolyte container, the electrolyte is distributed over a space -.ττοη which he at least one further space which is separate from the first and in which the electrodes flow are housed. In contrast to the invention, there is only a single battery there, which is composed of several electrodes, and thus can in the known devices also only a single relatively low voltage can be obtained.

The invention is explained in more detail below using two exemplary embodiments.

In Fig. 1 1 denotes a centrally located in the proximity fuse, essentially cylindrical space in which a container 2 with electrolyte 3 is arranged. The wall 4 of the cylindrical space consists of insulating material; on the rear side there are openings 18 through which a part of the electrolyte can flow into the space 6 after the wall of the container 2 has been destroyed by means of a pointed member. The rest of the electrolyte remains in the space ι. In the event of retardation forces the electrolyte of the space 6 penetrates ⁶ S electrodes 13 and 15 to the spaces between the annular. Part of it flows through the openings 21 in the lower electrode into the space 7, the air present being expelled. For this purpose, the electrode 15 is located on the inside at a distance from the wall 4. An insulating spacer ring 14 is attached between the electrodes. Absorbent material can also be placed in the space between the electrodes.

The electrolyte remaining in the space 1 moves after the projectile leaves the barrel has, forward and passes through openings 18 'between the electrodes 10 and 11, which through a spacer ring 12 are separated from each other. The excess electrolyte ends up in the Room 5, which serves as an air buffer. The excess air and the excess electrolyte flow in the process through the openings 20.

Longitudinal slots 16 and 17 in the wall of the insulating Support bodies are used to attach the current conductors.

Rooms 6 and 7 are separated by a wall, along which the electrolyte is placed on the right Is led away. Here, too, the excess air is discharged. For the same purpose can the space 5 can be provided with a lateral opening.

F i g. 2 shows an embodiment in which the electrodes 28, 29, 30 and 31 are wound cylindrically are, which has the advantage that the construction has greater mechanical strength. Of the Electrolyte moves backwards after breaking the wall of the container 2 and fills the Clear 21 and 22. After the delay forces have occurred, the electrolyte moves forward, so that first the spaces 23 and 24 and then the spaces between the electrodes 28 and 29 or 30 and 31 must be completed. There is a porous spacer layer between the electrodes arranged.

It is of course possible to provide more than two rooms 21, 22, whereby the number of Parts of the battery are enlarged. The parts are completely isolated from each other, so none Loss currents occur. Insulating, cylindrical partitions 25, 26, 27 serve as separators.

The device according to FIG. 2 can also be used with twist projectiles.
