Claims

[Scope of Claim for Utility Model Registration] (1) A piston in which a thick-walled sleeve is fitted around the outer periphery of the rod on the lower side of the piston, and the lower end of the sleeve is formed in the center of the inner surface of the lower cover of the cylinder even when the lower end of the sleeve is at the piston's rising end. It has a length that slightly penetrates into the concave portion having a depth greater than the throat talk, thereby forming an independent air chamber for the piston return movement within the concave portion. An air cylinder characterized in that the tip of the compressed air inlet faces into the reciprocating air chamber. (2) The cylinder top cover is provided with a compressed air inlet for piston forward movement toward the top surface of the piston, and the cylinder bottom cover is provided with an air bleed port for the piston forward movement air chamber surrounded by the cylinder wall. An air cylinder according to claim 1 of the utility model registration claim.
