ABSTRACT:
The disclosure relates to a dental treatment chair which contains in its backrest a dispensing controller for compressed air and water to be distributed to the dental instruments of the chair; the controller includes a distributing block for air and water, air-pressure-operated on-off valves, and couplings to connect flexible connecting pipes connected to the instruments to the supply source side. The chair can reduce the number of compressed air and water pipes leading from the seat body to the backrest of the chair and can diminish the distance of piping between the dental instruments and the dispensing controller to reduce passage resistance.
