Abstract

Apparatus for automatically stabilizing, at an adjustable value, the pressure or the depression in a duct or in an enclosure and, more particularly, but not exclusively, in a combustion chamber, by action on a register that controls the passage section of the duct outlet by means of a sheet that can move in a sleeve that divides into two compartments, one subjected to atmospheric pressure and the other to the pressure prevailing inside the duct to which it is attached upstream of the aforementioned register, so that any increase in pressure, upstream of this register, pushes the sheet that then causes the record to open, while any depression attracts said sheet to cause the closure of said record, the regulation of the apparatus itself being obtained, in order to determine the pressure or depression that will automatically reign upstream of the register, by modification of the equilibrium position of the "register" o-sheet "by means of a counterweight, this apparatus being characterized in that the sleeve is curved according to a constant radius whose geometric center is the axis of rotation of the register, to which the sheet is supported in rotation by means of a support that it passes through the duct, entering the inside of the sleeve through a hole in said duct, the plane containing the longitudinal axis of the duct, on the one hand, and the curved path of a point on the sheet, on the other hand, passing perpendicularly by the axis of rotation of the record.
