SEALING STRUCTURE BETWEEN MEMBERS, AND GASKET

摘要

PROBLEM TO BE SOLVED: To provide a sealing structure between members, which controls a phenomenon (flow) in which a sealing part of sheets composed of expanded graphite is dropped down from fatigue or collapsed and pushed out and a gasket useful in the sealing structure. SOLUTION: The gasket 32 equipped with sheets 36 and 37 composed of expanded graphite is laid between two members (the cylinder block 12 and the cylinder head 13 of an engine) to be mutually connected by tightening to seal a fluid (combustion gas). In the seal structure, the sheets 36 and 37 have seal parts 42 with 1.85-2.00g/cm3density in a state in which the sheets are assembled between the cylinder block 12 and the cylinder block 13. Sheets in which the seal parts 42 having 1.50-1.70g/cm3density in a state before attachment to an engine are used as the sheets 36 and 37. COPYRIGHT: (C)2007,JPO&INPIT
