Based on a device of the type mentioned at the beginning This object is achieved according to the invention by that the air pump and its drive motor in a manner known per se from the housing that can be guided by hand built away and combined to form a motor-pump unit that the hand-feasible, with dsm preparation container can be equipped with the housing with the dispensing nozzle, the Air supply line, the foam generator and e-inpsa Switching element for controlling the air flow through the Air supply line to a foam applicator is united, which is connected to the air pump of the motor-pump unit via a flexible external connection line is connected, and that the motor-pump unit at the same time as a stand for at least one, preferably swei or more foam applicators are formed. The part of the device to be handled by the operator, namely the foam application device, is thus the weight of the air pump and the drive motor and the energy source for the drive motor and thus improves fatigue-free handling. the The performance of the motor and pump can therefore also be increased, since the increased weight of the motor-pump unit has no effect on the handling of the foam application device. The drive power of the motor or the delivery rate of the pump can also be increased to such an extent that several Foam application equipment with the required increased Air volume can be supplied. Then there is only one motor-pump unit for the supply of several devices is required, the total costs can be compared to equipping with known devices with a built-in motor, Pump and battery can even be lowered.

The motor-pump unit 10, which is composed of an air pump 16, preferably designed as a diaphragm pump, and a mains-fed electric motor 18, is consciously removed from the application devices 12 in a manner known per se (DT-Gbm 1 99k 775) in order to save weight accordingly, the drive power of the motor 18 must be such that a sufficient amount of air is available to operate the two foam application devices 12, is between the '. The outlet of the pump 16 and each application device a throttle 20 is switched on, which restricts the air delivery quantity to the size required for the respective device when the second - or possibly provided further - foam application device 12 is not in operation. In the schematic representation according to FIG. 1, the throttles 20 are shown in the motor-pump unit 10, but it can be seen that these throttles could also be built into the associated foam application devices.

In Figure 2, an embodiment of the device shown only schematically in Figure 1 is illustrated. The Motc 'pump unit fO has this. Exemplary embodiment has a flat housing 22, which is rectangular in plan view, in which the pump 16 described in connection with FIG. 1 and the mains-fed electric motor 18 are installed. About raittig on the top of the housing 22 is a transverse. Placed running vertical wall Zk, in which a handle opening 26 is formed, which allows easy gripping and transport of the motor-pump unit 10. In the part of the upper side of the housing 22 lying in front of the wall Zk in FIG. 2, two shallow standing depressions 28 are provided at some distance from one another, into each of which the lower end of a preparation container of a foam applicator 12 fits. In the drawing, only one such application device 12 is shown, while the second device is omitted for the sake of clarity. It should be pointed out, however, that if the output of the motor 18 and the pump 16 are appropriately designed, more than two foam applications β ge advises β 12 can be connected to the motor-pump unit 10.

For additional security in the stand indentations 28 used foam application devices 12 has the Handle opening 26 has bulges 30 on its lower delimiting edge, into which the dispensing nozzles explained in more detail below in connection with FIG the foam application devices 12 can be inserted appropriately.
