AIR COMPRESSOR

Abstract: The air compressor, as a unit with a drive motor, a compressor means connected to the drive motor, and a pressure vessel with a compressed-air inlet opening and an outlet opening, is designed in such a way that it can alternatively be used as a spraying device for liquids or powdery substances, for which its pressure vessel (14) can be used as a material container with a compressed-air cushion in combination with a suitable application device for the material to be sprayed and to this end is additionally provided on its top side with a relatively large opening for loading the material to be sprayed and for cleaning, which opening can be tightly closed by means of a lid (26) in a pressure-resistant manner. <IMAGE>

Claims: Air compressor, comprising a drive motor and compressor (18) connected thereto, and a pressure vessel which is used as a material container with compressed-air cushion in conjunction with a matching applicating device and which is for this purpose provided at its top with a relatively large opening (23) for filling with spray material and for cleaning, which is closed so as to be tight and pressureproof by means of a cover (26), and which comprises a compressed-air inlet opening in the container wall near the edge (22) of the top opening (23) and an outlet opening in the cover (26), characterised in that two selectively usable connecting sockets (32, 33) of the pressure vessel (14) are provided, of which one (33) is arranged at the lowest place of the pressure vessel bottom (16) and the other in the cover (26), and that a compensating vessel (20) with condensed-water separator is positioned in the compressed-air pipe (19) between the compressor (18) and the compressed-air inlet opening (21) of the pressure vessel (14). Air compressor according to claim 1, characterised in that the compensating vessel is arranged to be a compressed-air reservoir (40) and positioned together with the compressor (18) on a mutual support (45) which is detachably connected to the frame (10) of the air compressor by means of wing nuts (46). Air compressor according to claim 1 or 2, characterised in that on the cover (26') of the compressed-air container (14') is detachably attached a material pump (50), which is connected on the suction side to a suction pipe (34'), which is connected to the outlet opening (32'), and to which a compressed-air drive-link pipe (19") is connected to the compressor unit (18) or to the compressed-air reservoir (40). Air compressor according to one of claims 1 to 3, comprising a pressure vessel of annular-cylindrical cross-section, characterised in that the pressure vessel (14) is arranged with vertical axis (15) alongside the compressor (18) and its drive motor on the frame (10) which is movable in a conventional manner and therefore provided below the pressure vessel (14) with an axle (12) for two runners (13) and on the end near the vessel with at least one handle (36) for tipping the frame (10) around the axle (12).
