Abstract

Usage: mechanical engineering, gymnastic pneumatic. SUMMARY OF THE INVENTION: A pneumatic element comprises a sealed cylindrical straight tube with one closed end and a fitting on the other. The closed end of the tube is made with an outer pocket. A protector can be fixed on the inner surface of the bottom of the latter. 1 s.p., f-ly, 4 ill.

Description

The invention relates to mechanical engineering and can be used in pneumatic mats.

The purpose of the invention is to improve operating conditions and increase reliability.

In Fig.1 shows a pneumatic element, a longitudinal section; in Fig.2 - section aa in Fig.1; on figs. and 4 - options for patch pockets.

The pneumatic element contains a tube 1 made of highly elastic material, such as rubber, in the form of a long cylinder closed at the ends by bottoms 2, hermetically connected to the tube. In one of the bottoms 2 there is a fitting 3 with a through hole through which the internal cavity of the tube 1 is connected to the outer space . Through the nozzle 3, compressed gas, for example, air, is supplied to the tube 1, and thus, the elasticity of the element is changed. The fitting 3 compresses the overlap thereby exiting the gas from the tube 1, therefore, when the tube 1 is compressed, the pressure in it increases, and therefore the elasticity of the tube. Tubes 1 are installed in the channels of various

devices where they should work as resilient elements. In order for their elasticity to increase as the load on them increases, the tubes 1 must be enclosed in narrow channels, the walls of which must prevent the buckling of the chambers. To facilitate the insertion of the tubes 1 into the channels, the outer pocket 4 is made on the closed end of the tube 1 and is open towards the nozzle 3, and to prevent the pocket 4 from being destroyed by the rod inserted into the pocket 4 (not shown), a protector tape is fixed inside the pocket 4 5 made of high strength material. The pocket 4 can be made not integral with the tube 1, as shown in Fig. 1, but fixed in the form of a visor 6 at the closed end of the tube 1 (see box 3) or in the form of a cap 7 (see figure 4). In all possible pocket designs, it must be strong enough to allow the tube 1 to be pulled through the narrow channel of its container.

The manufacture of a pneumatic element can be made from sections of a cylindrical tube by cutting into pieces

with

of a known length and attachment of the bottoms 2 on both sides and the pocket 4 by known methods. The manufacture can also be carried out by stamping two longitudinal halves and then gluing them together or finally extruding the entire tube with bottoms and a fitting. In the manufacture of pockets according to Figs. 3 and 4, they are attached to the pipe 1 by glue or sintering.

Claims (2)

The formula of the invention 1. Pneumatic element containing a sealed cylindrical rectilinear 0 a tube of highly elastic material with one closed end and a fitting on the other, characterized in that, in order to improve operating conditions, the closed end of the tube is made with an outer pocket with an open end facing the nozzle. 2. The pneumatic element according to claim 1, with the exception of the fact that, in order to increase reliability, it is equipped with a tread fixed to the inner surface of the bottom of the pocket.
