Air compressor cylinder, air compressor, vehicle seat, and vehicle

Abstract

The invention relates to an air compressor cylinder, an air compressor, an automobile seat and an automobile. The air compressor cylinder is suitable for a piston type air compressor, a cavity is defined in a cylinder block of the cylinder, a liner is attached to an inner sidewall of the cavity, the liner is securely bonded to the inner sidewall, and the liner defines a compression cavity of the air compressor.

1 . A cylinder for a piston type air compressor, wherein a cavity is defined in a cylinder block of the cylinder, a liner is attached to an inner sidewall of the cavity, the liner is securely bonded to the inner sidewall, and the liner defines a compression cavity of the air compressor. 
     
     
         2 . The cylinder of  claim 1 , wherein a smoothness of an inner surface of the liner is greater than the smoothness of a surface of the cylinder block itself. 
     
     
         3 . The cylinder of  claim 1 , wherein the liner is die cast together with the cylinder block. 
     
     
         4 . The cylinder of  claim 1 , wherein securing between the liner and the cylinder block is achieved by a threaded connection. 
     
     
         5 . The cylinder of  claim 1 , wherein the inner sidewall of the liner is in a straight cylindrical shape and shape and size of a cross-section of the liner at both ends are the same. 
     
     
         6 . The cylinder of  claim 1 , wherein the liner is a deep drawn tube made of aluminum or aluminum alloy. 
     
     
         7 . The cylinder of  claim 6 , wherein the cylinder is die cast by zinc or zinc alloy with the liner. 
     
     
         8 . A piston type air compressor, wherein a cylinder of the air compressor is the cylinder of  claim 1 . 
     
     
         9 . An automobile seat, wherein the piston type air compressor of  claim 8  is provided in the automobile seat. 
     
     
         10 . An automobile, wherein the automobile is provided with the piston type air compressor of  claim 8 . 
     
     
         11 . An automobile, wherein the automobile is provided with the automobile seat of  claim 9 .
