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 4):
The sealing structure for a housing join of a fluid machine according to  claim 3 , wherein the width of the bottom surface of the ring groove is smaller than the wire diameter, in the width direction of the bottom surface of the ring groove, of the O ring compressed between the bottom surface of the ring groove and the end surface of the second housing member.
