Abstract: A thermostat having elastic member according to an embodiment of the present invention comprises: a valve body in which a first valve opening or closing a first passage is formed on end end; a retainer forming in which a second valve opening or closing a second passage is formed on the other end; and an operating part in which the first valve closes the first passage by elastically supporting the retainer in a direction in which the first passage is formed, in which the second valve pushes the retainer and an elastic member opening the second passage to a direction in which the second passage is formed according to the temperature, and in which the first valve opens the first passage. Therefore, the elastic member is not arranged in a wax case in which wax is fully charged, so that thermal exchange between the wax case and cooling water is smoothly performed. In addition, the elastic member is not arranged on the outer circumference of the valve body, so that the elastic member does not prevent the flow of cooling water and flow resistance of the cooling water is reduced. Also, the wax recognizes the temperature of cooling water as quickly as possible so that the temperature control of cooling water is accurately and quickly performed.

Abstract: According to an embodiment of the present invention, a thermostat with improved reactivity comprises: a thermostat case where one side is connected to a first flow path, and the other side is connected to a second flow path, and a third path is formed toward a side direction between the first flow path and the second flow path; a valve body having a mounting space in an inside where a first valve for opening and closing the first flow path is formed in one side, and where a second valve for opening and closing the second flow path is formed in the other side; an elastic member for making the first valve to close the first flow path by elastic supporting the valve body toward the first valve direction; and a driving part for moving the valve body according to contracting and expanding of a wax arranged in the mounting space of the valve body. A flowing conversion wall can be formed in a part corresponding to the third flow path of the valve body to move a fluid flowing through the second fluid path toward the opposite direction to the third flow path. Therefore, the flowing conversion wall formed on the valve guide can improve the whole reactivity in which the thermostat reacts to the temperature of a cooling water since the flowing conversion wall makes the cooling water to pass a wax case.
