Abstract: The module (2) comprises a tubular body (8) extending along a first axis (10) with at least one radial outlet (12). The module (2) has a female end-piece (16) at one extremity and a corresponding male end-piece (14) at the other. Bore holes (22, 28) extending along a plane which is substantially perpendicular to the first axis are provided on both sides of the module (2) at each of the ends thereof. When two modules (2) are fitted into each other, the bore holes (22) of one module are aligned with the bore holes (28) of the other module on both sides of the unit thus created. When the bore holes are parallel, adjacent modules are fixed by means of a U-shaped bracket whereby the branches thereof are placed in the aligned bore holes.

Abstract: 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.
