Claim:
A pump action sporting air rifle of the type comprising a barrel ( 1 ) with sheath ( 27 ), bottle ( 2 ) of compressed air or CO2, a bottle hand-guard ( 29 ), a valve ( 4 ), a butt ( 7 ), a trigger ( 5 ), a trigger-guard ( 6 ), a safety catch ( 20 ), a hammer ( 9 ) fixed to its disc ( 21 ) with said hammer ( 9 ) facing the valve ( 4 ) with an anti-fall safety device ( 19 ) between the two, and a chassis ( 30 ) characterised in that it comprises: a drag skid ( 26 ) connected to the hand-guard ( 6 ) and sheath ( 27 ), a sliding rod ( 25 ) joined by one of its ends to the drag skid ( 26 ) and by the other to a slider device ( 11 ), the mentioned slider device ( 11 ) consisting of an interior stop ( 28 ), an upper face ( 31 ) supporting a tilting part ( 12 ), an upper arm ( 32 ) that encloses a chamber ( 7 ), a drum shaft ( 13 ), one of the ends of which passes through the centre of the drum ( 8 ), with the other positioned between the tilting part ( 12 ) and the chamber ( 7 ), the referred drum ( 8 ) has orifices ( 33 ) for allowing the chamber to pass through, and a safety bolt ( 10 ) in front of the hammer disc ( 21 ), which tilts and moves when the pressure from said disc ( 21 ) disappears, thus the slider ( 11 ) blocks said safety bolt ( 10 ), so that on moving backward, said hand-guard ( 29 ) pulls the drag skid ( 26 ), moves the sliding rod ( 25 ) which moves the slider ( 11 ) backwards, also tilting the tilting part ( 12 ) and chamber ( 17 ), rotating the drum ( 8 ) to the next orifice ( 33 ) and moving the hammer ( 9 ) backwards through the action of a lower stop ( 28 ) on the slider ( 11 ) that pushes the hammer disc ( 21 ) backwards, thus removing the pressure on the safety bolt ( 10 ) which then moves and crosses, at least partially, the forward movement of the slider ( 11 ).
