DEVICE FOR SEALING A FLUID CIRCULATION DUCT, SUCH AS AN AIR DUCT OR A VENTILATION OPENING
The invention relates to a sealing device (2) comprising a flap (6) which is mounted to the end of a fluid circulation duct (3) in an articulated manner between an open position in which the fluid can flow through the duct and a closed position in which the fluid is prevented form flowing through the duct. In addition, a flexible spring tongue (7) is mounted to the flap between the flap and the duct, such that it can be applied hermetically against the circumference of the mouth of the duct (3) when the flap is in the closed position and such that it controls the flow of fluid entering the duct when the flap is in the open position, by deforming as a function of the pressure inside the duct.

The invention concerns a device comprising a recycling motorized hood (5) and an air extracting conduit designed to be connected to a controlled mechanical ventilation installation. The box of the hood communicates through an opening (10) with the extraction conduit (12). Another air intake (13) is provided which emerges into the conduit (12). Said air intake (13) is closed and the opening (10) is free when the hood fan (8) is operating, and inversely when the fan (8) is off.

METHOD FOR CONTROLLING PRESSURE DELIVERED BY THE VARIABLE SPEED FAN OF A VENTILATION DEVICE
The inventive method consists in defining a device loss of load and in calculating a minimum required pressure corresponding to a minimum flow rate and a maximum required pressure corresponding to a maximum flow rate, in defining a flow rate/pressure curve between two predetermined points corresponding to the minimum pressure and flow rate and to the maximum pressure and flow rate, in measuring the air flow rate passing through a fan, in calculating the required pressure using the flow rate/pressure curve and in subsequently controlling the fan speed of rotation in such a way that said required pressure value is delivered.
