Abstract:
To provide a sealing structure for a housing join of a fluid machine such as a compressor or expander, which can prevent a twist in an O ring and resultant reduction in sealing property. The sealing structure for a housing join of a fluid machine, which is used to seal a join between a first housing member  1  and a second housing member  2  that constitute a housing of the fluid machine, includes: a ring groove  14  formed in an end surface  11  of the first housing member  1 , and an O ring  3  to be inserted into the ring groove  14 . The ring groove  14  has an inverted trapezoid shape in cross section, and when the first housing member  1  and the second housing member  2  are joined together, the inserted O ring  3  is compressed between a bottom surface  14 a  and an end surface  21  of the second housing member  2  and the compressed O ring  3  comes into contact with the bottom surface  14 a  and both of a pair of side surfaces  14 b,  14 c  extending upward from the bottom surface  14 a  at its opposite ends in a width direction.

Claim (Index 2):
The sealing structure for a housing join of a fluid machine according to  claim 1 , wherein the ring groove is formed such that before the first and second housing members are joined together, the inserted O ring comes into contact with the bottom surface and one of the pair of side surfaces and also, an upper portion of the inserted O ring protrudes from the opening edge.
