Multistage and Double Acting Pneumatic Cylinder

摘要

The present invention includes a base housing part having a base accommodating space formed on the inside, and air flowing into the lower and upper sides, respectively, being accommodated in the base accommodating space and having an extended accommodating space formed inside the base housing part, and flowing into the lower side of the base housing part. The extension part moved in the upward direction by air and moved downward by the air flowing into the upper side of the base housing part and accommodated in the extended accommodation space, and upward by the air flowing into the lower part of the base housing part. Disclosed is a multi-stage double-acting pneumatic cylinder including a piston part that is moved and that is moved in a downward direction by air flowing into an upper side of the base housing part.
