HYDRAULIC DRIVE WITH FEEDBACK BY POSITION OF ACTUATOR AND WITH MECHANISM OF UNLOADING Russian patent published in 2011 - IPC F15B9/00

Abstract RU 2437002 C2

FIELD: machine building.

SUBSTANCE: hydraulic drive with feedback consists of at least two hydro-cylinders with sensors of feedback by position of hydro-cylinder rod. By means of flexible pipelines the hydro-cylinders are connected with a control unit wherein there are arranged electro-hydraulic amplifiers, pressure gauges, a drain valve and also an unloading mechanism consisting of a relief valve and a system of feedback determining pressure of working fluid required for displacement of the most loaded rod of the hydro-cylinder.

EFFECT: raised reliability.
