The proposed, according to the invention, apparatus for testing a recoil brake and a rolling rod is made in the form of a combustion cylinder in which a piston is disposed with a rod mechanically connected to the recoil stems and the rolling rod. The device makes it possible to simulate the effect of a shot on the tested mechanisms of a rollback brake and an inaccuracy.

The dryness of the invention is illustrated in FIG. 1 which shows a longitudinal section of the combustion cylinder; FIG. 2 is a view of the cylinder from the end; FIG. 3 shows the general view of the device in plan, FIG. 4 is a cross-section of it along the line / - / in FIG. 3

The device for testing the hydraulic brake of recoil and knurling is made in the form of a combustion cylinder (bomb) A, in which the piston B can be mixed, with a piston B.

The movement of the rod is transmitted through the cross member With the recoil and idler brake rods. All three cylinders — a bomb, a rollback brake, and a nakatnik — are mounted on one common ground (Fig. 3 and 4).

A charge of gunpowder is placed in the combustion chamber D of the bomb, the ignition of which is carried out in the usual way, such as in the Viell bomb. The ballistic calculation shows that by selecting a sample of gunpowder, you can get a piston recoil curve, similar to the recoil curve of an artillery system. This makes it possible to carry out tests and investigations of the operation of recoil devices under conditions similar to a shot, but with minimal costs.

The device allows:

a) test the recoil brake and knurling brake (removal of the working diagram in the case of a new design),

b) in serial production to produce a test for the operation of the collar and omental

seals

c) carry out research work on liquids used in artillery systems, as well as on the determination of the coefficients of outflow of fluid at high speeds and pressures. The subject matter was invented by the device for testing the recoil brake and knurling, I distinguish it from “4” with the fact that it is made in the entrance of the combustion cylinder A, in which the piston B is located with the rod connected to the recoil stems and knurling rod, for example, the cross member G, with the aim of imitation of the effect of a shot on the test mechanisms of the brake recoil and knurling.
