  • Patent number: 6029645
    Abstract: The invention discloses a compressed gas-operated pistol (1) with a gas capsule (15) arranged in a grip member (5), which is in operative connection with a valve system (33) of the pistol (1). The secure receipt and piercing of the gas capsule (15) is effected through an abutment (17) which completes an inherent displacement and an external displacement superimposed on this inherent displacement. The external displacement is thereby effected by a support element (23) of the abutment (17) which is contacted by capsule tensioner (25). (FIG. 2).

  • Patent number: 5906191
    Abstract: The invention discloses a compressed gas-operated firearm (1), especially a pistol, which at the utilization of a drum (18) for multi-shot projectile receipt distinguishes itself through a linearly displaceable weapon barrel (3) to achieve a loading position, or, respectively, firing position, and through a trigger (4) which is automatically secured against actuation in the loading position. Furthermore, a new type of valve system (25) is proposed for the impulse-like emission of the compressed gas upon the discharge of a shot.
