FIELD: construction. ^ SUBSTANCE: controller comprises multiple louver plates adapted to be installed in a frame and to rotate in it around the longitudinal axis between the specified position, in which the louver plates are combined to close or to limit a part of a channel, and the open position for passage of air between plates of louvers and through a channel, an inclined mechanism to impact every louver plate so that in process of usage each louver plate is adapted to be held in the specified position until the specified air flow to the plates is achieved, at the same time the inclined mechanism is a spacer mechanism, capable of impacting every louver plate for its rotation into the specified position and represents a gas spacer connected to a lever mechanism acting at louver plates, for their displacement into the specified position, at the same time at the air flow specified the louver plates are capable of impacting the lever mechanism, which is capable of impacting the gas spacer as each plate is displaced towards the open position. ^ EFFECT: protection of mechanism against excessive force and automation of operation. ^ 14 cl, 9 ex, 18 dwg |
