Abstract (en)
[origin: US6394361B1] In a device including a first calibrated or adjustable orifice and a second orifice located downstream of the first orifice, the opening of the second orifice is adjusted by a valve whereof the position is controlled by apparatus displacing the valve depending on the pressure difference prevailing between upstream and downstream of the first orifice and by apparatus producing a displacement depending on the temperature of the premises wherein the device is located. The device is mounted in two separate bodies, mutually linked, a first body corresponding to the first orifice and a second body corresponding to the second orifice. The device enables to produce both automatic hydraulic balancing and thermostatic control.
