Fig. 1. The gun according to claim I, characterized by the fact that, in order to provide an operative adjustment of the force bo, the cylinder is provided with locks of row i of consecutive handle positions. 3. Gun POPP.1 and 2, characterized in that, in order to improve its usability in operation, in the cylinder wall there is a through longitudinal slit with a length equal to the piston stroke in it, and sealed with a piston, while the handle holders are made in the slit in the form of cuffs.

The invention relates to weapons for throwing without the use of warheads, namely, to a pneumatic harpoon gun and for spearfishing.

The closest to the invention with the technical essence and the achieved result is a non-expendable pneumatic harpoon gun containing a barrel with a sealed chamber, a piston movably mounted in the chamber and dividing its volume on the compression cavity to the vacuum section, the plunger connected to the front part of the piston a) a barrel nozzle with a channel- communicated with the cavity of a vacuum chamber and seal, interacting with the pusher and harpoon, and the trigger mechanism P.

A disadvantage of the known device are the small bo power, as well as the lack of prompt adjustment of the bo power.

The purpose of the image, the shadows - increasing the power of the bo, as well as providing rapid adjustment of the power of the bo and increasing the convenience of the gun in operation.

This goal is achieved by the fact that a cost-free pneumatic harpoon gun containing a barrel with a sealed chamber, a piston movably mounted in the chamber and its volume on a compression and rarefaction cavity, a pusher connected to the front part, a piston, a barrel nozzle with a channel communicated with a vacuum chamber and a seal interacting with the pusher and harpoon, and the trigger mechanism is equipped with a cylinder with a sealed chamber in which the piston is movably mounted, dividing its volume by

compression and vacuum cavities and having an actuator made in the form of a movable and hermetically mounted in the cylinder handle with a retainer associated with the piston and placed outside the cylinder, while the compression and vacuum cavities of both chambers are respectively connected to each other by channels.

In addition, the cylinder is provided with locks for a number of consecutive positions of the handle,

In the wall of the cylinder there is a through longitudinal slit with a length equal to the stroke of the piston in it, and sealed with a piston, with the handle latches made in the slot in the form of cuffs.

FIG. 1 depicts a cost-free pneumatic harpoon gun; in fig. 2 and 3 - cylinder with front and rear piston positions.

The gun contains a barrel I with an airtight chamber 2, a piston 3, sub-: mounted in the chamber 2 and separating its volume into cavities 4 and 5, respectively, of compression and rarefaction, a pusher 6 connected to the front of the piston 3, barrel nozzle 7 with a channel 8 communicated with the cavity 5 of the vacuum chamber 2 and having a seal 9, interacting with. pusher and harpoon (not shown), and the trigger mechanism.

The rifle is equipped with a cylinder 10 with a sealed chamber P, in which a piston 12 is movably mounted, dividing its volume on cavities 13 and} 4, respectively, compression and vacuum and having a drive made in the form of a handle 15 movably and hermetically installed in cylinder IO with clamps, piston 12 and placed outside the cylinder 10, with

Claims (3)

,1. A UNLAIMABLE PNEUMATIC HARPOON GUN, containing a barrel with a sealed chamber, a piston movably mounted in the chamber and dividing its volume into the cavity communicated with the chamber rarefaction chamber and seal, interacting with the pusher and the harpoon, and the trigger mechanism, distinguishes - furthermore that, in order to increase the battle force, it is equipped with a cylinder with a sealed chamber in which a piston is movably mounted, dividing its volume into compression and rarefaction cavities and having a drive made in the form of a movably and hermetically mounted unit hydrochloric cylinder lock with handles associated with the piston and the cylinder is placed, 'compression and rarefaction pusher coupled th front part of the piston, the nozzle receiver to the channel, wherein the compression and rarefaction cavity two chambers respectively are interconnected channels. 2. A shotgun according to claim 1, characterized in that, in order to ensure operational adjustment of the battle force, the cylinder is equipped with row locks; sequential handle positions. 3. Shotgun popp 1 and 2, characterized in that, in order to increase its convenience in operation, a through longitudinal slot is made in the cylinder wall with a length equal to the stroke of the piston in it, and sealed with a piston, while the handle latches are made in the slot in the form lapels.
