摘要:
Cooling control systems described herein detect decreased operation of a cooling system of a vehicle, restrict movement of the vehicle without stopping movement responsive to decreased operation of the cooling system, and restrict movement of the vehicle by preventing the vehicle from traveling at a speed and/or power output for a non-zero designated period of time. This can allow for the vehicle to continue moving for a temporary period of time to avoid blocking traffic. Other control systems determine predicted distances and/or times that the vehicle can continue moving before coolant in the cooling system decreases below a designated threshold. Movement of the vehicle can be changed responsive to an upcoming distance and/or time that the vehicle is to travel exceeding the predicted distance and/or time. Other control systems modify a coolant flow rate based on differences between designated and ambient conditions.

The present invention relates to an actuating device with an electromotive rotary drive, via which an actuating element can be driven rotatably about an axis of rotation between a first end position and a second end position and can be acted upon out of the first end position by a spring. The electromotive actuating drive includes a reversing drive and the spring action upon the actuating element is effective between the first end position and an intermediate position. The spring action is ineffective between the intermediate position and the second end position. The intermediate position lies between the first end position and the second end position.

The invention is based on a control valve (10) for a control circuit (30) having at least one first control unit (14) that, depending on at least one operating parameter and/or the ambient temperature, releases, throttles, or closes a branch of flow (32) to a heat exchanger (16), and controls a bypass line (34) in complementary fashion. It is proposed that the control unit (14) generate a setpoint (36) for the position of a valve member (26) driven via electric motor or electromagnetically, which is processed by a second electronic control unit (20) integrated in the control valve (10) with a determined actual value (38) of the position of the valve member (26) to a position variable for the position of the valve member (26).

A refrigerant control valve apparatus includes a valve body provided with a main control valve controlling the refrigerant sent to a discharge port and a temperature sensing control valve controlling supply and discharge of the refrigerant to a temperature sensing chamber. A fail-safe mechanism is provided which supplies the refrigerant to the discharge port in a case where the temperature of the refrigerant exceeds a set value. The temperature sensing control valve is set in an open posture in a case where the main control valve is in a closed posture that closes the discharge port and the temperature sensing control valve is set in a closed posture in a case where the main control valve is in an open posture that opens the discharge port.

The present invention relates to a method for protecting an engine from short circuiting and wire failure of a fan clutch, and a device thereof wherein the method for protecting an engine comprises: a step of sensing the temperature of a coolant if a fan rotates at a set minimum rpm by the short circuiting and wire failure of a fan clutch; a step of comparing the sensed coolant temperature and a set danger temperature; and a step of defaulting if the sensed coolant temperature is lower than the set danger temperature and reducing the engine rpm if the sensed coolant temperature is equal to or higher than the set danger temperature according to a result of the comparison such that overheating of the engine can be prevented. The engine rpm is gradually lowered so as to protect the engine at a first stage if the fan operates at the minimum rpm due to the cable short cut and failure of the fan clutch, and the engine is forcedly stopped so as to protect the engine at a second stage if the overheating of the coolant is serious, thereby ensuring durability of the engine.
