Title:
TUBE AND PNEUMATIC DEVICE WITH THE TUBE
Document Type and Number:
WIPO Patent Application WO/2004/023018
Kind Code:
A1
Abstract:
A tube that is simple in structure and low in cost, and a pneumatic device with the tube are disclosed. Adopting the tube enables to reduce the number of tubes in a device. A tube (10) is a tube where two-passage air communication passages (16, 18) are formed. A partition plate portion (12) is provided between the air communication passages (16, 18). A wall thickness (t1) between a tube outer wall (10S) and each of the air communication passages (16, 18) is set constant. This enables to reduce waste of resin forming the tube, realizing tube (10) that is simple in structure, low in cost, and light in weight. Further, installing the tube (10) in an air cylinder (20) reduces the number of tubes required.
