Publication number: 20080159895Abstract: A sealing structure includes a first substrate having a first compartment, a second compartment and a first base surface. A first element, disposed between the first and second compartments, a second element and a third element, moves between a first initial position and a first predetermined position. The first element has a first acting surface and the second element has a second acting surface. The third element includes a body, a first sectioned part having a first main conjunctive surface, and a second sectioned part having a second main conjunctive surface. When the first element is moved to the first predetermined position, the body is clamped between the first and second acting surfaces, and the first main conjunctive surface contacts the second main conjunctive surface. Thus, the deformed third element pressing against the first base surface separates the first compartment from the second compartment.Type: ApplicationFiled: May 30, 2007Publication date: July 3, 2008Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Shu-Er Huang, Chun-Chung Yang, Kun-Yi Liang, Yu-Choung Chang

Patent number: 7207787Abstract: A scroll compressor with a backflow-proof mechanism. The scroll compressor comprises a slider disposed on a scroll couple, forming several enclosed spaces. The slider is raised by the working fluid in the spaces, preventing liquid leakage from a high-pressure chamber to a low-pressure chamber, when the scroll compressor starts. The slider descends when the compression ratio of the scroll compressor is exceeded. Thus, the pressure is released, and the performance of the scroll compressor is improved. The slider of the invention further comprises a floating element to prevent reversal of pressurized fluid and damage to the scroll couple.Type: GrantFiled: July 16, 2004Date of Patent: April 24, 2007Assignee: Industrial Technology Research InstituteInventors: Kun-Yi Liang, Shu-Er Huang, Ching-Feng Lai, Yu-Choung Chang
