HYDROMECHANICAL POWER ELEMENT Russian patent published in 2022 - IPC E21B37/10 

FIELD: mining industry.

SUBSTANCE: invention relates to the mining industry, in particular to hydromechanical power elements and can be used for directed destruction and softening of various objects by creating cracks in them in a given direction. The device includes a housing, made in the form of an upper and lower cages, connected by segment cheeks to form longitudinal openings in the casing, in which the punches are movably mounted, and they are connected to the casing cages by return leaf springs. In the upper end cap, rigidly installed in the upper cage, there is a guide channel connected to the internal cavity of the elastic chamber, in which a stepped plunger is hermetically mounted with the possibility of axial movement. The lower end cap, rigidly installed in the lower cage, is provided with an elongated cone located inside the cavity of the elastic chamber.

EFFECT: efficient pulsed radial impact on the borehole walls is provided, the service life, structural strength, and reliability are increased.
