Reservoir for one in pneumatic systems * Work medium used preferably in motor vehicles

The invention relates to a storage "containers for« la in pneumatic systems, preferably in motor vehicles used _t working medium with more than one connection point.

Pneumatic systems are used in motor vehicles. wise for the central locking of all doors, com Penster opening or closing «ad used for similar devices that are operated pneumatically. To the Operation of the devices is mostly used under pressure, which is taken from the intake manifold of the internal combustion engine will. In order to operate the devices and another ge

The object of the invention is ea, on the one hand pneumatic
To be able to operate devices of various types in motor vehicles independently of one another and at the same time to simplify the manufacture of the necessary storage containers.

This object is achieved by the invention in that
that the storage container has more than one chamber and each chamber is provided with a connection for the pneumatic lines. The storage container arrived

The divided chambers can also be of different sizes or the same size, so that it is possible to change the size of the Kaaaern dea can be adapted to the respective purpose · By dividing the container into different chambers even the wall thickness can be reduced somewhat, since the partition walls also act as reinforcement · Im The rest of the chamber wall * is arched so that the container does not collapse in the event of high evacuation. Furthermore, beads can be embossed, which serve the same purpose.

Such a trained according to the invention storage container can be manufactured economically because “Only a single production step is necessary for a production, although several chambers are produced. This training allows optimal use of space and also a short assembly time Achieve vehicle.

The invention will be described in the following description on the basis of an exemplary embodiment shown in the drawing explained in more detail, which can also be found in further details of the subject matter of the invention. Show it
