Principle and characteristic analysis of multi position air cylinder

Principle and characteristics of three position air cylinder: one method is to arrange two similar air cylinders with the same air cylinder diameter and different stroke in series, and the stroke of the rear acting air cylinder is greater than that of the first acting air cylinder. Another method is that the air cylinders are arranged back-to-back, the extension direction of the plunger rod is opposite, and the piston rod at one end is fixed. When the two air cylinders have the same stroke, three working positions can be obtained.

Principle and characteristics of four position air cylinder: the four position air cylinder has two SMC air cylinders with different strokes. The piston rod of the air cylinder is opposite and the piston rod at one end is fixed. Four working positions can be obtained by successively controlling the actions of two motorcycle air cylinders.
