Title: Scroll-type compressor
Inventor: NAMIKI KEN
IPC: F04C18/02
Filed: 2022-03-15
Abstract: To improve the reliability of a scroll-type compressor.SOLUTION: Each of grooves 41 is partially covered with a swirling spiral wall 26b which opposes a compression chamber 27 on the way of compression communicating with each of sub-discharge ports 40 so as to make the compression chamber 27 on the way of different compression and the compression chamber 27 communicating with a main discharge port 25h not communicate with each other. Then, each groove 41 constantly communicates with any of the compression chambers 27. By this constitution, an operation region in which each sub-discharge port 40 does not communicate with the inside of the compression chamber 27 is reduced compared with the case that each groove 41 is not formed at a fixed baseboard 25a on which each sub-discharge port 40 is formed. Therefore, a refrigerant gas is discharged from each sub-discharge port 40 in a further wider operation region. As a result, since an operation region in which a refrigerant gas cannot be discharged from each sub-discharge port 40 is reduced, an operation region in which pressure in the compression chamber 27 abnormally becomes high is reduced.SELECTED DRAWING: Figure 4
