PROBLEM TO BE SOLVED: To suppress the leakage of fluid from the mating face between the casings of a fluid machine which is constructed by combining the pair of casings. SOLUTION: The upper side casing 2A has an inside protruded strip 5I and an outside protruded strip 5E. The inside protruded strip 5I and the inside protruded strip 5E are protruded from the mating face 4A of the upper side casing 2A. The outside protruded strip 5E is formed on a first flange 7A, and the inside protruded strip 5I is formed right under a casing wall 2Aw of the upper side casing 2A. The inside protruded strip 5I is arranged at a predetermined space l7 from an inner face 2Aiw between a bolt 10 and the inner face 2Aiw of the upper side casing 2A on the side of the mating face 4A of the upper side casing 2A. A distance l1 from the bolt 10 to the inside protruded strip 5I is set to be shorter than a distance l2 from the bolt 10 to the outside protruded strip 5E (l1<l2). COPYRIGHT: (C)2010,JPO&INPIT |
