Abstract
Погружной измеритель крепости горных пород, включающий гидроцилиндр, нагрузочный поршень со штоком, оснащенным индентором, отличающийся тем, что гидроцилиндр выполнен с тремя концентрическими полостями: входной, кольцевой и напорной, и оснащен дополнительным бесштоковым поршнем с двумя цилиндрическими поверхностями, взаимодействующими с входной и кольцевой полостями гидроцилиндра, при этом между кольцевой полостью под дополнительным бесштоковым поршнем и напорной полостью нагрузочного поршня со штоком обеспечена гидравлическая связь посредством канала. A submersible rock strength meter, including a hydraulic cylinder, a loading piston with a rod equipped with an indenter, characterized in that the hydraulic cylinder is made with three concentric cavities: inlet, annular and pressure, and is equipped with an additional rodless piston with two cylindrical surfaces interacting with the inlet and annular cavities hydraulic cylinder, while between the annular cavity under the additional rodless piston and the pressure cavity of the load piston with the rod provided hydraulic ide through the channel.
