Valve plate of a piston cylinder

Abstract

The structure of an air outlet valve plate of a piston cylinder of an air pump is disclosed. The air outlet valve plates comprises a cylinder mount, an air outlet valve plate, a cylinder, a cylinder inner pad and piston module, characterized in that the cylinder mount is locked to the cylinder by a locking element with the air outlet valve plate being positioned between the mount and the cylinder, and each of a branch plate of the valve plate is corresponding to each of the air hole on the top face of the cylinder, and the valve plate is a plate body with circular connection edge, and the interior of the valve plate is extended outward to form a plurality of equal branch plates, and an equidistant gap s formed between each of the branch plate and the branch plate is independently to be opened or closed, and the bottom face of the connection edge is provided with at least one positioning edge which is corresponding to the sealing pads arranged between the cylinder mount and the cylinder of the positioning edge slot, and an urging branch plate within the interior of the cylinder mount urges and restricts each of the branch plate of the air outlet valve plates such that the opening and closing of each of the branch plate are synchronized and of same aptitude of swinging such that the air flow rate of each air hole is uniform and equal.

1 . A valve-plate of a piston cylinder of an air pump comprising a cylinder mount, an air outlet valve plate, a cylinder, a cylinder inner pad and piston module, characterized in that the cylinder mount is locked to the cylinder by a locking element with the air outlet valve plate being positioned between the mount and the cylinder, and each of a branch plate of the valve plate is corresponding to each of the air hole on the top face of the cylinder, and the valve plate is a plate body with circular connection edge, and the interior of the valve plate is extended outward to form a plurality of equal branch plates, and an equidistant gap s formed between each of the branch plate and the branch plate is independently to be opened or closed, and the bottom face of the connection edge is provided with at least one positioning edge which is corresponding to the sealing pads arranged between the cylinder mount and the cylinder of the positioning edge slot, and an urging branch plate within the interior of the cylinder mount urges and restricts each of the branch plate of the air outlet valve plates such that the opening and closing of each of the branch plate are synchronized and of same aptitude of swinging such that the air flow rate of each air hole is uniform and equal.  
   
   
       2 . The valves plate of a piston cylinder of  claim 1 , wherein the piston module is mounted with one or at least one air inlet hole and a sealing plate according to the need of the air inlet flow rate.  
   
   
       3 . The valve plate of a piston cylinder of  claim 1 , wherein the interior of the cylinder is mounted with a wear-resistant inner pad for cylinder.
