Gas powered gun with velocity regulator

摘要

A gas powered gun comprising a valve arranged to exhaust compressed gas from a chamber to thereby discharge a projectile inside a barrel, and a hammer arranged to be cooperate with a valve opening arrangement to thereby open the valve. A spring is arranged between the hammer and a spring abutment for spring loading the hammer. The gun further comprises an adjustment knob turnable around an axis A of rotation, substantially perpendicular to the spring loading direction. The knob has a cam surface having a varying radial distance from the axis of rotation, and a follower, integrated with the spring abutment, is pressed by the spring to rest against the cam surface. When the adjustment knob is turned, the follower will slide against the cam surface and move the follower and the spring abutment in the spring loading direction, to thereby adjust a pretension of the spring.

1. A gas powered gun for discharge of projectiles, comprising:
a valve arranged to exhaust compressed gas from a pressure chamber to thereby discharge a projectile inside a barrel; a hammer; a movable spring abutment; a spring arranged between said hammer and said spring abutment and arranged to spring load said hammer in a spring loading direction; an adjustment knob including:
a gripping portion, allowing a user to grip said adjustment knob and to turn said adjustment knob around an axis (A) of rotation, said axis of rotation being substantially perpendicular to said spring loading direction,a cam surface extending around said axis of rotation and having a varying radial distance from said axis of rotation; and a follower, coupled with said spring abutment and pressed by said spring in said spring loading direction to rest against said cam surface; so that, when said adjustment knob is turned, said follower will slide against said cam surface and move said follower and said spring abutment in said spring loading direction, to thereby adjust a pretension of said spring.
