Claim Text:
1. A compressed air gun, comprising: a body, comprising a compressed air passage conduit including an upstream conduit that extends along a first axis and a downstream air ejection conduit, and a hole which extends along a second axis not parallel to the first axis and which emerges in the upstream conduit, a closing member, which is translatable, parallel to the second axis, inside the hole between a closed position, where the closing member blocks passage of air in the upstream conduit, and an open position, where the air is free to flow between the upstream conduit and the downstream conduit, a trigger controlling the movement of the closing member, which can be manipulated between a released configuration, where the trigger keeps the closing member in the closed position, and a blowing configuration, where the closing member is in the open position, return means for returning the trigger to the released configuration, a tubular sleeve immobilized inside the upstream conduit and extending parallel to the first axis, the tubular sleeve including two opposite orifices positioned at downstream and upstream ends of the sleeve and between which extends an air passage, wherein the closing member, in the closed position, is suitable for closing off the orifice of the air passage at the downstream end of the sleeve by forming a sealed contact with the downstream end of the sleeve and wherein the sleeve delimits a contact surface with the closing member, which is positioned in an oblique plane relative to a plane perpendicular to the first axis and wherein the contact surface of the sleeve is an annular surface having elliptical inner and outer contours.
