    Device for testing components subjected to high pressure in a tensile-compression machine that allows to evaluate them under static stresses and fatigue, comprises a pressure intensifier with a cylinder through which runs a rod, a first flange crossed by the stem, a valve communicates with a cylinder chamber, with a second flange, a third flange houses the free end of the rod; the tension-compression machine comprises two jaws, the device comprises first clamping means, a jaw can print its movement to the rod through the third flange and the first clamping means, a bearing tube houses the pressure intensifier, also it comprises a test tube next to the valve so that it opens into its interior, thus a fluid arranged in the chamber can be compressed by the movement of the stem inside the test tube.

    same purpose as mentioned to keep the fluid within an optimum temperature range for the validation of the test.
    Another option, within this same embodiment, is that the first means of
    5 fasteners (4) comprise a fourth flange (4.1) crossed by a first screw (4.2) which is inserted into a first wedge (4.3) that is housed in the corresponding housing of one of the jaws (2), as shown in figure 1.
    Another option, within this same embodiment, is that the second means of
    10 fasteners (6) comprise a fifth flange (6.1) disposed at the free end of the carrier tube (5) opposite the end where the stem (1.2), a second screw, comes out
    (6.2) that crosses the fifth flange (6.1) and that is inserted in a second wedge (6.3) that is housed in the corresponding housing of one of the jaws (3), as shown in Figure 1.
    Another option, within this same embodiment, represented in Figure 1 is that when the first clamping means (4) are fixed to the lower jaw (2) and the second clamping means (6) are fixed to the upper jaw (3), that is in the orientation in which the rod (1.2) is towards the lower jaw (2), the device
    20 comprises a vessel (8) disposed supported on the third flange (1.8) for collecting any fluid discharged from the device.
    For simplicity of representation in the flanges (1.4,1.7,1,8,4.1,6.1) the screws or bolts that pass through them have been omitted.
