- Liquid system which at least one arranged in the interior of the scattering container form and
- volume changeable tank bag comprises.
- spreaders For smoothness control on traffic areas (roads, paths, squares, runways, apron) widespread blunting and / or thawing scattering substances are applied.
- usually spreaders are used, as they are well known in various designs. In the interests of the highest possible efficiency, such spreaders generally have a fluid system which can be particularly adapted to moisten the solid (for example granular) spreading material to be dispensed by means of the spreader discharge device. Because not only
- Spreading material on the sprinkled surface improves, thereby reducing the risk of transporting discharged spreading material through the air swirls of fast moving vehicles.
- the ratio between the solid spreading material to be applied and the liquid used for wetting it depends on a large number of factors. Under certain conditions it is even favorable to use pure liquid (eg Brine) on the traffic surface, including typically an additional Sprühausstattung for
- the aim is to optimize the efficiency of the anti-slipperiness in the sense that with
- Bandwidth can vary. For this are in the
- Interior of the scattering container is arranged at least one shape and volume changeable tank bag. Depending on the degree of its filling, a more or less large “residual space" is available for the absorption of solid scattering material.
- the present invention is directed to a
- the spreader according to the invention which has the features set forth in the introduction, is characterized in particular by the fact that - in synergetic manner
- Ventilation has, which via a

- Tank bag on its upper side two spaced apart in the longitudinal direction of the spreader ventilation sockets which communicate with each other via a connecting line.
- Ventilation pipe by means of a connecting line, such a backflow of liquid contained in the tank bag - through said connecting line - allows that in specific driving situations (especially during heavy braking of the vehicle)
- Tanksacks by sloshing of the liquid contained in particular during acceleration and braking of the
- Arrangement of at least one winch, for example, on one of the end walls of the scattering container may be particularly favorable, in particular in the case of a synchronized adjustment of several partitions by the flexible
- Pulling means of several partitions on a common winch can be wound up.
- another effect on the flexible traction means is possible as by winds, for example (with or without previous deflection of the flexible traction means on rollers, rollers or
- the pivoting or other adjusting drive for the at least one partition wall can be designed as a spring drive. This applies in particular if - in the above sense - a straps, belts, ropes or comparable flexible traction comprehensive swing drive for the at least one
- Partition is provided.
- a spring drive which may for example comprise a tension spring, act, in the sense of a reduction of that subspace, which is bounded by the respective flexible traction means associated partition.
- the respective partition can at
- the spring as a in the longitudinal direction of the spreader be executed extending tension spring, in which case the flexible traction means is deflected via a roller or other deflection.
- the respective partition adjustment is designed as a spring drive in the above sense, is also favorable to provide at least one separate partition stop element which defines the maximum possible volume of the respective subspace corresponding position of the partition.
- Such dividing wall stop elements may advantageously be in turn flexible, for example by execution as straps or belts, which are above the tank in question between the respective partition and a fixed component (side wall, cover, or the like.)
- Subspace acting active adjustability of the partition by means of an adjusting drive is usually sufficient because the hydrostatic pressure acting in the tank by the liquid absorbed in it and is absorbed by the partition, acts on the latter in the sense of increasing the volume of the subspace ,
- said sub-chamber receiving the tank-bag may further be delimited by a side wall of the scattering container and / or the partition wall - in particular in the region of its lower edge - can be pivoted sideways so that the adjusting drive is designed as a swivel drive.

H. not variable with the partition wall position variable but rather relative to the side walls of the scattering container
- the spreader has, in this sense, at least two tank sacks arranged one behind the other in the longitudinal direction of the spreader, the two are particularly preferred

- each tank bag is suspended at its opposite upper edge regions on the associated partition and on the side wall of the scattering container. In this way, a collapse of the tank bag at its
- the at least one tank bag remains at least substantially at the same height even in the partially filled state as in its fully filled state.
- partition wall-side suspension can be carried out in particular in the area of the partition stiffening struts, which in turn preferably extend to joints, by means of which the partition is pivotally articulated.
- the ventilation stubs can be used in particular spatial proximity to the side wall side suspensions of the respective bag to be arranged.
- the scattering container has at least one rigid, arranged above the ventilation stub,

- Partition wall can act a trickle seal. This ensures that when filling the scattering container with solid, in particular granular scattering material, when - while minimizing the volume of the subspace for the tank bag - the partition is pivoted to the stop on the cover, no solid scattering material passes into the subspace. This increases the service life of the tank bag and can thus further increase the reliability and reliability
- the present invention is characterized in that at least one rigid liquid head tank is arranged in front of the front end wall of the scattering container, wherein the ventilation system of the at least one tank bag communicates with the interior of the head tank.

It is particularly advantageous if the at least one tank bag (based on its maximum volume entirely or at least 90%) is arranged above the level of the at least one side tank. This results in a hierarchical removal of liquid from the at least one tank bag and the at least one in the sense
- the at least one side tank is removed.
- a spatial arrangement of tanks and side tanks relative to each other is favorable, if, according to a preferred
- At least one intermediate floor is arranged, on which rests the at least one tank bag.
- the intermediate bottom is considerably above the scattering material discharge device
- the intermediate bottom is perforated more or less pronounced, so that the subspace limited by it down through openings with the underlying portion of the scattering container communicated. For example, any foreign objects that have entered the subspace can leave it downwards and be removed from the spreader together with the solid spreading material.
