Patent number: 7520299Abstract: A valve includes a valve body forming a first flow passage and a second flow passage that connects to the-first flow passage through a first opening and a seating element forming a bypass passage that connects the first flow passage and the second flow passage. The bypass passage opening has a smaller cross-sectional area than the first opening. The valve also includes a valve control element that can be repositioned to open both the first opening and the second opening, open the second opening while closing the first opening or close both the first opening and the second opening. The bypass passage may allow fluid to drain through the valve to prevent fluid from building up in the valve. If fluid becomes frozen, the valve may become stuck shut. In some embodiments, the bypass passage opens only if the temperature creates a possibility of freezing in the valve.Type: GrantFiled: March 3, 2006Date of Patent: April 21, 2009Assignee: Nissan Motor Co., Ltd.Inventors: Masanari Yanagisawa, Iwane Inokuchi
