FIELD: oil and gas industry.
SUBSTANCE: invention relates to devices for sampling of horizon fluids from gas and oil wells at specified depth. The technical result is achieved in the mechanism of valve control by means of the following: in a case with a bushing and a plunger with holes for a calibrated pin positioned therein the mechanism is additionally equipped with a device in form of a cartridge located in the case of the mechanism above the bushing and interacting with the upper part of the plunger equipped with sealing rings insulating a cavity of the cartridge placed above the upper part of the plunger.
EFFECT: upgraded reliability and quality of sampling at any horizon conditions including aggressiveness of horizon and also possibility of operation of mechanism valve control with majority of employed types of samplers.
