<p><P>PROBLEM TO BE SOLVED: To provide a piston type compressor suppressing deformation of a sliding face with a rotary valve caused by deformation of a cylinder block. <P>SOLUTION: A rotary valve 35 rotating in synchronization with reciprocating motions of a piston 24 is used for suction valve mechanism 49 of a compressor 10. The rotary valve 35 is housed in a housing hole 17 formed in a cylinder block 11. A cylindrical sleeve 40 is housed in the housing hole 17. The sleeve 40 is supported by the cylinder block 11 in the housing hole 17 through an elastic member 41. The rotary valve 35 is slidably supported by a sliding face 40b which is an inner circumferential face of the sleeve 40. A clearance between an outer circumferential face 40a of the sleeve 40 and an inner circumferential face 17a of the housing hole forms a deformation suppression space 47 for suppressing the deformation of the cylinder block 11 from affecting the sliding face 40b. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
