摘要:
A coolant control valve apparatus 10 includes a main valve 11 which adjusts a flow rate of a coolant in a main channel 4 to control the flow rate of the coolant in the main channel 4. Further, the coolant control valve apparatus 10 includes a detour channel 67 provided being diverged from the main channel 4 so as to detour the main valve 11. The coolant control valve apparatus 10 includes a valve main body 41 which opens and closes the detour channel 67 and a temperature detection medium 42 which can open and close the valve main body 41 according to a temperature of the coolant. The temperature detection medium 42 is disposed in the diverging part between the detour channel 67 and the bypass channel 5.

In one embodiment of the present invention, a shape memory alloy (“SMA”)-actuated flow controller comprises a number of grille members, each having a long axis and being slideable relative to one another parallel to that long axis. The SMA-actuated flow controller also includes a frame configured to guide the number of grille members, and an actuator disposed within the frame to move at least one of the number of grille members for varying a size of an aperture. Further, the actuator includes an SMA actuator that includes a number of SMA elements each connecting one grille number to another.

A drain valve for a cooling system of a locomotive engine includes an orifice disposed in fluid communication with the cooling system of the engine, a flow restricting element communicable with the orifice, and an actuator mechanism disposed in mechanical communication with the flow restricting element. The actuator mechanism is fabricated of a shape memory metal.

A thermostat is actuated by a wax capsule adapted to operate on a main valve disposed in a fluid circuit immediately the temperature of the wax capsule exceeds a predetermined threshold. It comprises arrangements made at least in part from a single-acting memory alloy adapted to contribute to the operation of the thermostat only when their temperature is less than the transformation temperature of the alloy and to condition the flow of the fluid in the thermostat in the same direction as if the wax capsule had operated normally if the transformation temperature of the memory metal is exceeded.

A valve apparatus for the vehicle that may be disposed in a vehicle to exhaust operating fluid, which flows therein, to the outside, may include a main body that has at least one exhaust port and input port and the operating fluid flows there in through the input port, and an opening/closing unit that may be disposed in the main body, wherein the opening/closing unit selectively fluid-connects one of the at least a exhaust port with the input port according to a temperature of the operating fluid such that the inflow operating fluid may be exhausted to the outside through the exhaust port.

A water-cooled type engine cooling apparatus includes: an oil cooler that circulates cooling water flowing out of a water-cooled type engine; a water temperature detection unit that detects temperature of the cooling water; a switching unit that switches the oil cooler from an operating state to a halt state, and vice versa; and a switching control unit that controls switching of the switching unit. The switching control unit controls the switching unit to switch the oil cooler into the halt state when the temperature detected by the water temperature detection unit is lower than a preset temperature, and controls the switching unit to switch the oil cooler into the operating state when the temperature detected by the water temperature detection unit is not lower than the preset temperature.

An engine cooling module 10 includes a shroud 12 having at least one fan opening 15 and at least one additional opening 18 in the wall generally adjacent to the fan opening to permit air to pass though the shroud 12. A fan 14 is coupled to the shroud to permit air moved by the fan to pass through the shroud 12. An electric motor drives the fan. Closure structure 20 is movable to prevent and permit air flow through the additional opening 18. An actuator 28 moves the closure structure 20 from a closed position, covering the additional opening 18, to an opened position, uncovering the additional opening 18. A sensor 34 detects ram air at the shroud 12. A controller 32 receives a signal from the sensor 34 indicating the initial presence of ram air and, in response thereto, sends a signal to the actuator 28 to move the closure structure 20 to the opened position.

A safety radiator cap for radiator providing a safety plate or wire made of shape memory alloy. The safety plate or wire bends downward under ambient temperature. High temperature water in the radiator causes the safety plate to extend out due to the memory characteristic of the alloy, and the safety plate thus presses against the neck of the filling hole.
