The invention relates to structural elements of prefabricated units and is intended for use in hydraulic and pneumatic control systems.

A block is known that contains modules of the same type in construction — mounting sections with channels connected by common pull pin. The device can operate at a limited supply pressure of 1.

The closest in technical essence to the invention is a block of modules for hydraulic and pneumatic systems, comprising mounting sections with channels connected to one another by working planes by means of common tie-rods 2.

The disadvantage of this block is that when working under pressure from a pin, having a certain modulus of elasticity of the material, they obtain an elongation from the force exerted by the pressure of the working medium. As a result of the elongation of the studs, gaps are formed between the sections and the tightness of the system is broken.

The aim of the invention is to improve the reliability of sealing the connection sections.

This goal is achieved by the fact that in the module of modules for hydraulic and pneumatic systems, containing mounting sections with channels, connected to one another by working planes by means of common pin studs, at least one cylindrical socket connected to the channel is made in the working plane of one section supplying the working medium; a piston is installed in the socket, which is sealed to the diameter by a sealing ring;

In addition, in the working plane of the sections in each through channel, there is a cylindrical seat, and the piston located in the socket is made with an axial bore, the diameter of which is equal to the diameter of the through channel, and with an additional sealing ring. the plane of the next section.

FIG. 1 shows the connection of the mounting sealing section with the base, general view and section; in fig. 2 shows sealing of the through channel in the section.

The mounting sealing section 1 is connected to the base 2 (and to the other sections) by common tie rods 3. In section 1 there is a channel 4 for supplying the working medium.

In the working plane of section 1, cylindrical sockets 5 are made (in Fig. 1 an example of block construction with four sockets is shown) in which pistons 6 are installed with sealing rings 7. Sockets 5 are connected to channel 4.

The upper ends of the pistons 6 are in contact with the plane of the base 2. In the presence of a through channel 8 for supplying the working medium (FIG. 2), a slot 9 with a piston 10 is made coaxial to this channel. The piston has an O-ring And an additional o-ring 12. The piston 10 also an axial bore 13 is made,

equal in diameter to channel 8.

The total area of the area from the working medium is larger than the total area of the channels for supplying the working medium.

The device works as follows.

When the working medium is supplied under pressure, a clamping force appears in channel 4 (8), which is perceived by the pin studs 3 and tends to open the joints of the sections 1. Under the action of the force expanding pin 3, a certain elongation is obtained. At the same time the working pressure of the medium, acting on the end of the movable piston 6 (10), squeezes it out of the socket

5 (9) and presses to the working plane of the adjacent section, creating the compression force of the sections, choosing the elongated studs and reliably sealing the channel 4 (8).
