Compressor and kit repairing and inflating inflatable articles

Abstract

A non-lubricated, rotary vane compressor of maximum 10-70 litres/minute capacity, and having a pump body defining a cavity; a rotor having a cylindrical body housed in the cavity; a number of vanes; an inlet and outlet connected to the cavity; and a non-return valve fitted to the outlet.

1 . A non-lubricated, rotary vane compressor ( 13 ) of maximum 10-70 litres/minute capacity, and comprising a pump body ( 14 ) defining a cavity ( 15 ); a rotor ( 16 ) having a cylindrical body housed in said cavity ( 15 ); a number of vanes ( 27 ); and an inlet ( 25 ) and outlet ( 26 ) connected to said cavity ( 15 ); the compressor being characterized by a non-return valve ( 31 ) fitted to said outlet ( 26 ). 
     
     
         2 . A compressor as claimed in  claim 1 , characterized by comprising a block ( 18 ) defining said cavity ( 15 ); and a first and second flange ( 19 ,  20 ) fixed to opposite sides of said block ( 18 ); and wherein, of said block ( 18 ), said first and second flange ( 19 ,  20 ), said rotor ( 16 ), and said number of vanes ( 27 ), at least three are made of non-friction, non-metal material. 
     
     
         3 . A compressor as claimed in  claim 2 , characterized in that said non-metal material can be pressed and machined. 
     
     
         4 . A compressor as claimed in  claim 1 , characterized in that said inlet ( 25 ), said outlet ( 26 ), and said vanes ( 27 ) are so configured that at least one vane ( 27 ) is interposed angularly between said inlet ( 25 ) and said outlet ( 26 ) for each position of said rotor ( 16 ). 
     
     
         5 . A compressor as claimed in  claim 4 , characterized in that the ratio between the diameter of said cylindrical body and the maximum dimension of said cavity ( 15 ) in a direction perpendicular to the axis of rotation of said rotor ( 16 ) ranges between 0.6 and 0.9. 
     
     
         6 . A compressor as claimed in  claim 4 , characterized in that the maximum diameter of said cavity ( 15 ) is 50 mm. 
     
     
         7 . A compressor assembly comprising a direct-current motor with a maximum consumption of 5-25 amperes. 
     
     
         8 . A kit for repairing and inflating inflatable articles, and comprising a compressor or compressor assembly as claimed in  claim 1 .
