PURPOSE:To improve the compression efficiency of a fluid by providing vanes inside blades and by fitting springs at the bottoms of the vanes to increase the contact pressure between the vanes and the opposing inner wall face of a main body so that the compressed fluid is not leaked to other low pressure portion during compression. CONSTITUTION:When blades 5 are rotated by a drive shaft 13, guide rollers 8 provided at one end of swing blades 6 are moved along eccentric cam grooves 9, and the swing blades 6 are moved to the inner wall 4 side of a main body 1 using one end as a fulcrum then are moved to the blade 5 side in a circulating motion. As the swing blades 6 are moved in succession to the inner wall 4 side of the main body, the fluid is conveyed while being compressed and is discharged through a discharge port 3. Accordingly, vanes 17 are provided inside the blades 5, and springs 18 are fitted to the bottoms to increase the contact pressure of the opposing inner wall 4 face of the main body, thereby the sealing of a high pressure chamber 14 can be improved and the compressed fluid is prevented from being leaked from the high pressure chamber 14 to a low pressure chamber 15, thus the compression efficiency of the fluid can be improved. |
