ABSTRACT:
A compressed air generating device for forklift trucks in which a main pipeline connected to the end of the lift cylinder air chamber branches into a high-pressure air pipe and a return pipe, selectively communicating with the main pipeline through a switching valve means. With the main pipeline switched to communication with the main pipeline high-pressure air pipe, during the descending phase of the piston, air is sucked through an air suction pipe attached to the main pipeline into the lift cylinder air chamber, and during the rising phase of the piston, the air in the air chamber is compressed and is sent into an air tank as compressed air.
