Definitions

• the invention relates to a compressed gas-powered firearm, in particular a pistol, according to the preamble of claim 1.
• Such a firearm of the generic type is known from US Pat. No. 5,160,795.
• This known firearm has a frame on which the gun barrel is arranged.
• a drum for receiving projectiles or projectile bodies is provided, which is arranged rotatably about its axis on the barrel arrangement.
• the axis of rotation of the drum runs parallel to the longitudinal axis of the gun barrel.
• the rotary movement and the adjustment of the drum are carried out by means of a lever system which is operatively connected to the trigger system of the firearm.
• the gun barrel, together with the drum and the lever system for taking up the loading position can be pivoted upwards out of the frame via a front axis. In this swiveled-out position, the drum can be reloaded with new projectiles.
• valve system for the generic firearm, which is used in the frame behind the barrel arrangement.
• This valve system has a valve body which is sealed off at the end faces and receives a valve stem which is guided in a longitudinally movable manner.
• the chamber around the valve stem is connected to a compressed gas cartridge.
• the valve stem has a rear pin which is acted upon by the firearm's hammer.
• the front face of the valve stem acts on a spring-supported pin, which lies against the bore opening of the drum with a conical contact surface.
• valve stem is under the action of a compression spring and is moved forward by the hammer of the firearm when the trigger is actuated from its sealing system in a pulsed manner, whereby channels for gas or air pressure are released.
• This entire valve arrangement is in turn technically complex with many fitting parts, which is due to the pivoting device of the gun barrel with the drum used.
• DE 29 38 600 C2 discloses an ignition pin fuse for a handgun.
• This handgun is designed as a pistol and has a barrel and a carriage that can obviously be moved in a straight line.
• a trigger is pivotally mounted on the barrel against the action of a spring, which simultaneously actuates a locking device which engages in the advance path of the ignition pin.
• the decisive features are seen in the fact that the compressed gas-powered firearm known from the prior art has a linearly displaceable barrel arrangement in order to get from the firing position into the loading position and vice versa. Another essential feature ensures that the trigger of the firearm is automatically locked in the loading position.
• the straight-line displaceability of the barrel device and the drum which can thereby be detached from the barrel result in simple system parts and, at the same time, high shooting performance with optimum weapon safety.
• the barrel is moved into the loading position of the firearm by spring force as soon as the locking lever on the firearm's breech is pivoted manually into the unlocked position.
• the axis is simultaneously pulled out of the drum, which can then simply be removed from the weapon frame or breech for reloading. Pulling out the drum axis now causes the first arm of the double-armed lever to pivot radially into the theoretical center of the axis. As a result, the second arm is automatically moved into the axial path of movement of the slide, which blocks the entire trigger system.
• the sealing of the valve system with respect to the drum is also relatively simple.
• the front face of the hollow-cylindrical valve tappet is in direct sealing contact with the facing bore opening of the drum in the firing position when the shot is triggered. This takes place in a sensible manner by utilizing the released pressure gas. Special design measures to achieve a seal are not necessary on the end face of the tappet.

• Figure 6 shows the valve system of the firearm in section.
• the compressed gas-operated pistol 1 essentially consists of the breech 2 (also called frame), the barrel 3 arranged in the breech 2, the trigger system 4 and the handle 5.
• the front part 6 of the closure 2 receiving the barrel 3 is used in a straight line to move longitudinally from a loading position to a fire position and vice versa.
• the firearm 1 is in the closed position, which corresponds to the firing position.
• the locking lever 7 is in the locking position.
• a pivoting down of the locking lever 7 about the axis 8 leads to the unlocking and thus to the loading position of the firearm 1, in which the barrel 3 is moved forward by spring force support beyond the barrel mouth 9 shown in FIG.
• the firearm 1 is secured by a safety lever 10 which, in the position shown, a firing pin 11 in the line of action between the hammer or cock 12 and the plunger 13 (in FIG. 6: bolt 57 ⁇ or the valve plunger 55 to the valve system 25 brings what corresponds to the firing position "F.
• a manual swiveling of the safety lever 10 down to the position" S "turns the firing pin 11 from the line of action described above into the safety.
• the grip shell of the grip piece 5, in which a compressed gas cartridge or capsule 15 with, for example, CO 2 gas is located, can be opened via a grip shell button 14.
• a compressed gas cartridge or capsule 15 with, for example, CO 2 gas can be opened via a grip shell button 14.
• Other suitable gases and air with the appropriate pressure can also be used here.

• the slider 31 is carried along on the track 32 of the short arm 29 of the trigger 4.
• a cam track 33 is inserted in the slider 31, into which a bolt 34 is slidably inserted, which receives a control arm 35 in an articulated manner.
• This control arm 35 is at its free end under the pressure of a spring 36 and engages in the drive elements 23 of the drum 18 to produce a gradual rotary movement of the drum 18.
• the tip of the free end of the control arm 35 is shaped accordingly.
• the slide 31 has an adjustment edge 37 and 38 above the joint 30 and above the cam track 33, both of which are arranged at a distance from one another, which ensures ensures that an adjustment edge 37 or 38 always engages in the end positions of the slide 31 in corresponding adjustment recesses 39 on the circumference of the drum 18.
• the adjustment recesses 39 are located between the drum bores 19 and, in cooperation with the adjustment edges 37 and 38 of the slide 31, cause an exactly coaxial position between the drum bore 19 and the barrel bore 21 after the drum 18 has been rotated via the control arm 35 is in the firing position.
• the slide 31 By actuating the trigger 4 in the direction of the arrow 28, the slide 31 is moved forward, as a result of which the bolt 34 slides in the cam track 33 and controls the control arm 35 upwards. Since the tip of the control arm 35 is at a corresponding radial distance from the longitudinal axis 40 of the drum axis 22, the upward movement of the control arm 35 produces a stepwise rotary movement of the drum 18 on the axle pin 22.
• a trigger rod 41 is also operatively connected to trigger 4, which in turn is in a ratchet connection with hammer 12.
• the hammer 12 in turn is under the action of a spring 42 which exerts an acceleration of the hammer 12 which can be pivoted about the axis 43 in the direction of the firing pin 11.
