Air compressor having stabilized structure

Abstract

An air compressor includes a supporting base having a plate, a cylinder housing attached to the plate and having a chamber and an outlet tube communicating with the chamber of the cylinder housing for receiving pressurized air from the cylinder housing. A piston is slidably received in the cylinder housing, a gear is rotatably attached to the plate and includes an eccentric pin coupled to a piston rod to move the piston relative to the cylinder housing, and the gear is extended into a range of the cylinder housing for decreasing a distance between the gear and the piston rod and to facilitate a movement of the piston relative to the cylinder housing, and to prevent vibrations from being generated by the piston.

1 . An air compressor comprising: 
 a supporting base including a plate, a cylinder housing attached to said plate and including a chamber formed therein and having an inner diameter, and including an outlet tube communicating with said chamber of said cylinder housing for receiving pressurized air from said chamber of said cylinder housing, said cylinder housing including a thickness to define an outer diameter,    a piston slidably received in said chamber of said cylinder housing and having a piston rod extended therefrom,    a gear rotatably attached to said plate, and including an eccentric pin coupled to said piston rod, to move said piston relative to said cylinder housing, and said gear being extended into a range of said outer diameter of said cylinder housing for decreasing a distance between said gear and said piston rod and to facilitate a reciprocating movement of said piston relative to said cylinder housing, and to prevent vibrations from being generated by said piston, and    a motor attached to said plate and having a spindle extended through said plate and coupled to said gear for rotating said gear to move said piston relative to said cylinder housing in the reciprocating action, in order to generate pressurized air.    
   
   
       2 . The air compressor as claimed in  claim 1 , wherein an eccentric member is attached to said gear, and said eccentric pin is extended from said eccentric member.  
   
   
       3 . The air compressor as claimed in  claim 2 , wherein said plate includes a space formed by a peripheral casing to receive said eccentric member.  
   
   
       4 . The air compressor as claimed in  claim 1 , wherein said gear is selectively extendible into a range of said inner diameter of said cylinder housing for decreasing the distance between said gear and said piston rod.
