A device for regulation of the amount of air flow and/or mixture of two currents of air, in particular for connection to a heating fan and comprised of a housing (1) in which at least two registers (8, 9) are set up for regulation of the said air currents, so that closing one of the registers causes an opening of the other register and vice versa. The first register (8) is shaped like a two-armed lever, whose one arm (8a) is formed of at least one clack, whilst the other short arm (8b) is set up to at least work on the ingoing opening (9a, b) in the other register (9) at some distance from its centre of rotation (10, 11) so that the register's rotational axles are arranged at considerable right-angles toward each other, that the first register's (8) shorter arm of the respective lever (8b) is set up in the opening's (9a, b) extension of its upper and/or lower edge and that the shorter arm of the respective lever (8b) is designed to work together with a projection from the opening (9a, b) in relation to the eccentrically located pin in the openings fixed pivot (12, 13).<IMAGE> |
