Portable spray apparatus

A portable spray apparatus comprising:

• a back carrier frame;
• a blower unit mounted on said frame;
• a supply vessel mounted on said back carrier frame and having an interior space wherein a liquid spray medium and a solid dust medium are selectively held to be discharged by said apparatus;
• said blower unit including a drive motor and a blower driven by said drive motor to generate a blower airflow for selectively discharging the liquid spray medium and solid dust medium;
• an adaptor releasably connected to said supply vessel;
• a liquids channel for said liquid spray medium opening into said blower airflow;
• a solids channel for said solid dust medium opening into said blower airflow;
• said adaptor defining at least one channel section of said liquids channel and at least one channel section of said solids channel;
• said supply vessel and said adaptor having first and second built-in positions relative to each other and/or to said blower unit which are freely selectable by an operator of said apparatus and, in said first position, said liquids channel communicating with said interior space via said liquids section and, in said second position, said solids channel communicating with said interior space via said solids section;
• said supply vessel having a base having a center line;
• said base having a liquids opening formed therein assigned to said channel section of said liquids channel and a solids opening formed therein assigned to said channel section of said solids channel;
• said liquids opening and said solids opening being disposed on the same side of said center line;
• said adaptor having a center line;
• and,
• said channel section of said liquids channel and said channel section of said solids channel being disposed on different sides of said center line of said adaptor.
