Abstract:
A flow controller which is placed within a cooling fluid channel of an internal combustion engine and which is configured to control a flow of a cooling fluid flowing through the cooling fluid channel depending upon the temperature change of the cooling fluid, comprising:a cylindrical valve body which has an inlet opening and an outlet opening formed on a circumference of the valve body and which is fixed on a position where said inlet opening and said outlet opening are communicated with said cooling fluid channel; a fluid channel area which communicates said inlet opening and said outlet opening within said valve body; and a valve element which is configured to move forward and backward in the manner of crossing said channel area depending upon the temperature change of said cooling fluid, whereby said inlet opening and said outlet opening are opened or closed through the movement of said valve element to communicate or block said fluid channel area, wherein a bypass opening is formed on the circumference of said valve body, and said bypass opening and a bypass channel are communicated or blocked due to the movement of the valve element.
