A variable flow, modular-type terminal unit for conditioning rooms in a centralized conditioning system is provided with means for controlling the conditioned air flow arranged within the outlet diffuser in order to vary the cross-section area of the outlet ports, being operated by a thermostatic device. The thermostatic device, directly fed with conditioned air operates such controlling means through a control lever, a control rod displaceable in the direction of its length and a triangular lever hinged at one vertex for rotation in a plane parallel to that where the control lever is pivotedly mounted. The operating member of the thermostatic device engages the control lever through the end of a threaded rod adjustable for setting the operation temperature. Other two adjusting screws are provided for hand control of the maximum and minimum cross-section opening of the diffuser outlet ports, by limiting the control lever rotation in two opposite directions.
A terminal unit for the outlet of conditioned air in a centralized conditioning system, comprising a diffuser of conditioned air through outlet ports connected with a conditioning station and means for controlling conditioned air flow operated by a thermostatic device, wherein said conditioned air flow controlling means is positioned within the diffuser and is arranged to vary the outlet ports thereof, further comprising a device for conveying conditioned air directly to the thermostatic device and means for actuating the conveyer device at a predetermined pressure of conditioned air.
