EXECUTING MECHANISM AND METHOD OF IMPLEMENTATION OF THIS MECHANISM Russian patent published in 2009 - IPC E21B43/32 E21B34/06 

FIELD: mining.

SUBSTANCE: for actuation of said executing mechanism it is provided osmotic element. The osmotic element is placed into flow of fluid medium owing to which there is provided an effort and motion required for actuating executing mechanism on account of using the difference of values of osmotic pressure either between solution inside the osmotic element and external flow of fluid medium or in a layer containing this fluid medium relative to the said element. It results in corresponding displacement or adjustment of the valve, or regulating device, limiting inflow.

EFFECT: there is provided adjustment of process of reservoir drainage, consequently, water inflow into each section or into corresponding part of draining pipe is automatically regulated depending on amount of incoming water, owing to which water inflow is constantly maintained at minimal level.
