DEVICE FOR CONTROLLING TEMPERATURE OF COOLANT IN INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: after starting the engine, as temperature of coolant changes, voltage occurs at temperature pickup 6 resulting in actuating electronic relay 9 and setting in operation actuator 2. Three-stroke cock 1 is displaced to diminish deflection of controlled temperature of coolant. Simultaneously, voltage is fed to the input of the feedback. Adder 7 generates resulting voltage which begins to decrease. If voltage at the input of amplifier 8 is small enough, the relay is disconnected and the actuator stops. Immediately afterwards, capacitor 14 begins to discharge and actuator 2 is set in operation again. The pulses are fed to actuator 2 until temperature of coolant reaches optimum value. In operation of the engine, heat electric generator 13 generates power and is used for setting in operation of actuator 2. EFFECT: heightened accuracy of controlling. 2 cl, 2 dwg
