Class Information
Number: 29/888.022
Name: Metal working > Method of mechanical manufacture > Prime mover or fluid pump making > Fluid pump or compressor making > Scroll or peristaltic type
Description: Process wherein the manufactured fluid pump or compressor (1) employs in its operation at least one diaphragm member which is spirally wrapped, the walls of which define a closed space that serves as the working fluid chamber; (2) employs in its operation a resilient tubing that is compressed, which tubing serves as the working fluid chamber; or (3) a part especially adapted for (1) or (2) which is not elsewhere classified.
