The invention relates to housings for high pressure composite materials, used in particular in motor units.

The housings for high pressure composite materials are increased requirements to ensure their high reliability in long-term operation, excluding violations of the sealing and destruction during the basic work.

Known for building high pressure from composite materials containing power shell flange and elastic strips mounted on pole holes bottoms, lined on the inside coating of rubber-like material with the annular poiskovimi areas unfastening of the adhesive film between the coating and the sheath with flanges overlapping the edges of the flanges (patent RU №2108476, IPC6F 02 K 9/34, 1998).

Known similar cases, in which the compensation of the voltage between the flanges and the shell the placement of buildings should include the unreliability of the ring paskovich zones unfastening due to the failure of the relevant compliance under large deformation movements of the flanges under the high pressure in the housings, the structural failure, failure to function within the product.

As the closest analogue is adopted for the prototype is the case for high pressure composite material according to the patent RU No. 2108476.

The main objective is the creation of a new hull design with improved adaptation to uneven loads that occur because of the unlike poles of the power of the shells.

The technical result from the use of the invention is to improve the strength and reliability, ensuring stable functioning in the composition of the product without destruction.

The main problem is solved and the technical result is achieved due to design changes in paskovich areas unfastening, introducing new elements and use the properties of the elastic deformability of new materials on the basis of that concept compensate shear stresses in terms of the constrained compression heterogeneous layers corps, under excessive pressure high-temperature environment.

For this purpose, the case for high pressure composite materials containing power shell flange and elastic strips mounted on pole holes bottoms, oblastregional film between the coating and the shell flange, the overlapping edges of the flanges.

In the first embodiment

Ring polaskova zone unfastening provided with annular bands of elastic knitted nylon fabric, respectively installed with overlapping edges, a single adhesive film on the inner and outer contours, bonded with her tufting yarns and coated around the outer edge of the adhesive film and the outer surface of the flanges from the power shell - adhesive and elastic gaskets of rubber, and the floor in the ring paskovich areas unfastening reinforced at least a single layer of knitted nylon fabric.

According to the second variant

Ring polaskova zone unfastening equipped with dual narrow annular bands of elastic knitted nylon fabric with an anti-adhesive films between them, respectively installed with overlapping edges between two wide release films on the inner and outer contours, bonded with them tufting yarns and coated around the outer edges of the wide release films - elastic annular gasket of rubber and the outer surface of the flanges outside the enterprise in the ring paskovich areas unfastening reinforced at least a single layer of knitted nylon fabric.

Distinctive features of housing for high pressure composite materials are signs.

- reinforcement coating knitted nylon cloth in circular zones unfastening.

These features of the body for high-pressure composite materials are essential, as each of them separately and together is aimed at solving the problem and achieving a new technical result. In the first and in the second case, the body release the film in poiskovoy zone unfastening of the cover with the power shell is equipped bonded with her, as well as coated and flanges elastic annular bands of knitted nylon fabric, and floor in the area of fastening knitted nylon cloth, which allow a relative elastic deformation of the covering power of the shell and the flanges during curing of the preform body in heat treatment furnaces and basic operation of the case under high pressure without irregularities in the coating material and the destruction of the power of the shell.

These distinctive essential features are new, because their use in the prior art, anahiem the criterion of “novelty”.

One set of new essential features with commonly known essential features allows to solve the task of creating housing for high pressure composite materials and to achieve new technical results that characterizes new technical solution significant differences from the prior art, analogs and prototypes. A new technical solution is the result of research and creative contribution without the use of any standards or guidelines in the art is an original, non-obvious for specialists, which is made on the basis of the new concept of providing compensation shear stresses without changing the position of the adhesive film in paskovich areas unfastening relatively coating power shell and flange by fastening and fixing it on the inner and outer edges elastic ring belts knitted nylon fabric and coating in poiskovoy zone unfastening at least a layer of the same fabric characterized, respectively, the criterion of “inventive step”.

The invention is illustrated by drawings with a brief description:

In Fig.1 shows a General view to the axial direction of the show ring poiskovoy zone unfastening (enlarged scale) - the first variant of Fig.3 is a cross section of the shell in the area of the flange in an axial direction, showing the ring poiskovoy zone unfastening (enlarged scale) - the second option.
