Patent number: 8561914Abstract: The temperature-responsive fluid flow control apparatus of the present invention comprises: a housing installed between the inlet and the outlet of a fluid pipe in which a fluid flows; a valve block installed inside the housing to allow inflow of the flowing fluid in the housing and to discharge a portion of the flowing fluid to the outside according to the change in the internal pressure; and a temperature-responsive device for generating a pressure difference in the valve block according to the temperature change of the temperature-responsive fluid filled therein. The temperature-responsive fluid flow control apparatus prevents the fluid flowing pipe from freezing by discharging a portion of the fluid flowing in the housing to the outside, when the temperature of the temperature-responsive fluid reaches a preset temperature as the external temperature drops.Type: GrantFiled: December 9, 2009Date of Patent: October 22, 2013Assignee: Sudo Premium Engineering Co., Ltd.Inventor: Jaeyoung Jung
