Aromatizing device for air compressor apparatus

A aromatizing device for a dental air compressor which is mounted either in the compressor inlet or the feed tube between the compressor tank and pneumatic machinery. The air flows through a solid or liquid aromatizing agent in a chamber so that the agent is entrained therein to mask odors. The flow passage may be in parallel to the main passage and controlled to pass air and entrain agent for a predetermined time only following operation of the oil free air compressor.
The system having dental oil free compressors with an air inlet, an electric motor for driving said compressor, a tank coupled to a discharge side of the compressor and  a compressed air tube for connecting said tank with pneumatic machinery, said device comprising:means defining a chamber for holding a quantity of aromatizing agent and having an inlet and an outlet;means for connecting said chamber in a bypass flow path in parallel with said air tube including electrically operable valve means for opening and closing said bypass path; and control means for opening said valves means for a predetermined time in response to operation of said compressor so that air is partially and temporarily diverted through said bypass path to entrain said agent therein and mask odors.
As well known in the art, the pneumatic machinery as mentioned above is arranged to make use of the compressed-air supplied by the dental compressors, to perform its own work. During working, the pneumatic machinery discharges the compressed-air into the atmosphere and the compressed-air thus discharged into the atmosphere produces an uncomfortable environment.
