摘要

A device for automatic regulation and/or stabilization by direct action control on the incoming or outgoing flow to keep the flow flow in a one-way direction substantially constant, in particular but not exclusively gaseous, driven by a positive charge or difference of variable, unidirectional pressure in a directed or compulsory circulation path as an address conduit.u communication orifice, of the type with possibly substantially continuous variation of the cross-sectional area of free passage in inverse function of said load by at least a mobile internal main screen or similar, at least partially obturator with intrinsic recovery system, at least partially intercepting said fluid circulation and permanently exposed to its inlet pressure tending to move it from a position of rest with maximum opening to a position with progressive opening smaller in direct function of the amplitude of its current displacement, in whose position the force of the pressure is balanced by an antagonistic recovery force of intensity proportional to said relative displacement amplitude and which presses said screen in the opposite direction towards its position of maximum opening, characterized essentially by said device because it has at least one auxiliary transverse screen, partially sealing, with intrinsic recovery system, with a useful surface smaller than that of the main screen already mentioned and mounted in a corresponding hole thereof, in the form of to remain there sustained and mobile due to the aforementioned pressure, between, on the one hand, a resting position with maximum opening of said opening relative to the current position of said main screen and, on the other hand, a progressively reduced opening position. In proportional function with the amplitude of its current displacement, in which position the pressure active force is balanced with an antagonistic recovery force, of proportional intensity with said displacement amplitude and which presses said auxiliary screen in the opposite direction towards its maximum opening position, being the minimum effective value of said restoring force preferably greater than a predetermined effective value, for example maximum, of the restoring force acting on said main screen, while at least one of the mentioned screens occupies a part of the cross-section of free passage which regulates, while the other part of it is occupied by a deflecting transverse wall position, situated at the exit, preferably with a profile that progressively narrows said passage section in the direction of circulation, in such a way that it delimits, with said screen a step in zig-zag with variable strangulation according to the abatement of the aforementioned p it is provided that at least one of the aforementioned screens is mounted oscillating on a transverse oscillation axis and the aforementioned associated baffle wall position is constituted by an element a partition or the like forming a partial obstacle interposed in the path of circulation and has a free edge with an active profile preferably concave towards the entrance and whose distance to said axis of oscillation decreases in the direction of circulation up to a minimum value, to delimit between the respective free edges of said partition and partition element. Said screen a space or residual passage interval that decreases as it increases to the inclination or angular deviation of it towards the exit, in such a way that the recovery system of at least one of the aforementioned screens is a force field, for example of gravity, and the aforementioned screen forms a pendulum composed or similar suspend it is rotatably rotated with a transverse and substantially horizontal axis of oscillation, so that its resting position or stable weight balance is preferably substantially vertical, occupying for example the upper part of the associated passage section, whereas the aforementioned partition element occupies then the bottom.
