1 . High pressure compressor system for compressed air or gas rifles or pistols, of the type comprising a motor ( 1 ) that rotates a shaft ( 2 ); characterized in that:
 said shaft ( 2 ) is connected to at least one crankshaft ( 32 ) having at least two crankpins ( 7 , 8 ), a first crankpin ( 7 ) and a second crankpin ( 8 ), each of which is respectively attached to connecting rods ( 3 ,  4 ), which connecting rods ( 3 ,  4 ) are mutually outphased:
 a first connecting rod ( 3 ) connected to the first crankpin ( 7 ), which is attached to a first pin ( 9 ) connected to a first piston ( 11 ) which defines a first conduit ( 17 ) inside, and which ends at a first sleeve ( 28 ) that defines a first housing ( 27 ) that is connected to a first valve ( 15 ), 
 a second connecting rod ( 4 ) connected to the second crankpin ( 8 ), which is attached to a second pin ( 10 ), in turn connected to:
 a second piston ( 12 ), and 
 a second sleeve ( 13 ), said second sleeve ( 13 ) surrounding the first piston ( 11 ), and at least partially surrounding the second piston ( 12 ) and both crankpins ( 7 ,  8 ), said second sleeve ( 13 ) being connected to the first sleeve ( 28 ) and comprising through holes ( 5 ,  6 ) for the fluid to pass into the second sleeve ( 13 ), 
 
   and in that it comprises at least one guide tube ( 14 ,  19 ) that surrounds the second sleeve ( 13 ) and, at least partially, the second piston ( 12 ), and a second valve ( 16 ) that defines a fluid inlet into the second sleeve ( 13 );   
       wherein, when the shaft ( 2 ) driven by the motor ( 1 ) in a first stage:
 it moves the second crankpin ( 8 ), which drags the second connecting rod ( 4 ) towards the shaft ( 2 ), and said second connecting rod ( 4 ) moves the second piston ( 12 ) towards the shaft ( 2 ), opening the second valve ( 16 ) and allowing the inlet of the fluid into the second sleeve ( 13 ), and the second piston ( 12 ) drags the second sleeve ( 13 ) in the same forward direction as the second connecting rod ( 4 ), and 
 it moves the first crankpin ( 7 ), which drags the first connecting rod ( 3 ) towards the shaft ( 2 ), and said first connecting rod ( 3 ) pushes the first piston ( 11 ) towards the shaft ( 2 ) thus defining a second housing ( 20 ) between the second sleeve ( 13 ) and the first piston ( 11 ), and causing the fluid to pass from the second sleeve ( 13 ) through the first conduit ( 17 ) to the second housing ( 20 ), and dragging said second sleeve ( 13 ) to the first sleeve ( 28 ) and compressing the first housing ( 27 ), which pushes the fluid towards the first valve ( 15 ) wherefrom the fluid exits under pressure; 
 
       and when the shaft ( 2 ) continues to rotate as actuated by the motor ( 1 ) at a second stage:
 it moves the second crankpin ( 8 ), which drags the second connecting rod ( 4 ) in the opposite direction to the shaft ( 2 ), and said second connecting rod ( 4 ) moves the second piston ( 12 ) in the opposite direction to the shaft ( 2 ), thus closing the second valve ( 16 ) and preventing the gas from entering into the second sleeve ( 13 ) and the second piston ( 12 ) drags the second sleeve ( 13 ) in the same forward direction as the second connecting rod ( 4 ), and 
 it moves the first crankpin ( 7 ), which drags the first connecting rod ( 3 ) in the opposite direction to the shaft ( 2 ); said first connecting rod ( 3 ) moves the first piston ( 11 ) in the opposite direction to the shaft ( 2 ), thus reducing the volume of the second housing ( 20 ) and compressing the fluid therewithin, causing also the fluid to pass from the second housing ( 20 ) to the first housing ( 27 ), the fluid being thus pre-charged and ready to exit through the first valve ( 15 ) when the shaft ( 2 ) is rotated again, as actuated by the motor ( 1 ).
