ACTUATING MECHANISM FOR CONTROL OF DAMPER POSITION Russian patent published in 1998 - IPC

FIELD: heating systems for control of air temperature in cable of transport facilities; control of degree of opening of throttle valve. SUBSTANCE: actuating mechanism includes position sensor with movable and fixed parts and motor-reduction gear set including electric motor and reduction gear. Movable part of position sensor is connected with output shaft of reduction gear through member transmitting the rotation of output shaft of reduction gear to damper. Fixed part of position sensor is connected with housing of motor-reduction gear set. Member for transmitting the rotation of output shaft of reduction gear to damper may be made in form of lever, clutch, splined or flanged joint. EFFECT: simplified construction, reduced overall dimensions and mass and enhanced accuracy of control. 4 cl, 3 dwg
