METHOD AND DEVICE FOR STABILIZING FREQUENCY OF ROTATION OF CONSUMER OF INTERNAL COMBUSTION ENGINE Russian patent published in 2006 - IPC F16D43/26 F16H41/22 

FIELD: transport mechanical engineering.

SUBSTANCE: method of stabilizing frequency of rotation of consumer of internal combustion engine is based upon sustaining it within admissible deviation tolerance. Deviations are chosen on the base of admissible change in frequency of rotation of consumer; current frequency of rotation is measured and when its value reaches last top border of tolerance ω₁, torque is stopped to be applied from engine to consumer to provide free run of rotating parts of consumer. When the value reaches low border of tolerance ω₂ through transmission unit, torque is applied from engine to consumer, which torque is defined by mathematical relation. Device for stabilizing frequency of rotation of consumer of internal combustion engine has actuating unit and control unit with feedback. Actuating unit is made in form of hydraulic coupling with pump and turbine bends. Controlled friction coupling is mounted in space of hydraulic coupling. Friction coupling is provided with friction disc which interacts with back side of pump wheel and which forms booster cavity together with case of hydraulic coupling. The booster cavity communicates with hydraulic pressure source through hydraulic line. Booster cavity is provided with piston. Throttle outlet is also connected with hydraulic pressure source. The outlet is connected with working cavity of hydraulic coupling and it is provided with additional throttle, which is mounted onto external part of case of hydraulic coupling. Control unit is provided with detectors for measurement of frequency of rotation of engine's shaft and consumer's shaft, which are both connected with comparison unit, connected with eclectic-hydraulic valve mounted in hydraulic line of booster cavity.

EFFECT: permanency of turns of fan within specific range of frequencies of rotation of internal combustion engine.
