Abstract
A flow control valve is arranged to simultaneously perform coolant flow control and variable split cooling, according to control of a path opening degree of the flow control valve. The flow control valve can perform four-port control for variably controlling four ports at once by operation of the flow control valve, and thus can implement variable temperature control for increasing a temperature of an engine, rapid warming-up of the engine, while performing split cooling at the same time.
Claims15
A flow control valve, comprising:
- a valve housing including a block port connected to a coolant outlet of a cylinder block, a radiator port connected to a radiator, a heat exchanger port connected to an oil cooler or an EGR cooler, and a heater core port connected to a heater core;
- a driving unit that provides a rotational force;
- and
- a valve body that receives the rotational force provided from the driving unit to rotate in the valve housing at a predetermined angle, and has a first flow control hole, a second flow control hole, and a third flow control hole which are formed through the valve body such that the first flow control hole selectively communicates with the block port and the radiator port, the second flow control hole selectively communicates with the heat exchanger port, and the third flow control hole selectively communicates with the heater core port, according to changes of a rotation angle of the valve body.
