PURPOSE: To avoid the destruction of recyclable component elements and to decrease environment pollution problems by putting a spray mechanism having an electromotively driven gear pump into a housing which is connectable with a container for spray fluid by a close-fitted connection. CONSTITUTION: The spray mechanism 3 for finely spraying fluid by a hydraulically-operating pump is put into the housing 2 which is connectable with the container 4 of the spray fluid 5 by the close-fitted and/or frictional locking connection. The electromotively driven gear pump 12 is mounted at the spray mechanism 3. The suction pipe 13 of the pump 12 is introduced through the opening existing at the bottom of the housing 2 to the spray fluid container 4 with a ventilation pipe 26. A discharge pipe 14 disposed on the outlet side of the pump 12 is connected to an injection nozzle 15. Consequently, the destruction of the recyclable component elements may be avoided and the environment pollution problems may be decreased. Further, the satisfactory function in the long operating time may be assured even with all the spray media which can be adopted. |
