<p><P>PROBLEM TO BE SOLVED: To effectively reduce vibration and noise caused by pulsation of fluid without increasing size of a compressor and manufacturing cost. <P>SOLUTION: This compressor has a cylinder block in which bore forming a compression chamber for fluid is provided and a cylinder head provided to seal an end face of the cylinder block. The cylinder head has a central side space formed in its central part and an outer side space formed to surround the central side space, and the central side space and the outer side space are communicated with the compression chamber, respectively. This compressor is provided with a bulkhead partitioning the central side space into two chambers in the vertical direction for the direction of advance of fluid and a communicating hole provided in the bulkhead and communicating two chambers mutually. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
