HYDRAULIC VIBRATOR Russian patent published in 2016 - IPC B06B1/18 

FIELD: vibration equipment.

SUBSTANCE: invention relates to vibration equipment and can be used as generator of mechanical oscillations, for example, in hydraulic presses for pressing of wood or excavation machines for cutting of root systems of mature trees and stumps. Proposed hydraulic vibrator comprises housing, rigidly connected with distribution panel, equipped with check valves, connecting it with channels of rotary valve made in form of shaft with radial holes, and hydro valve installed with possibility to connect vibrator cavities to working cavities of power hydro cylinders, wherein rotary distributing valve is made in form of shaft with pairwise parallel radial holes, while working cavities of hydraulic cylinders are connected to each other through additional check valves.

EFFECT: technical result consists in simplifying design and expansion of technological capabilities due to obtaining of intermittent load on pistons of hydraulic cylinders at rated pressure.
