FIELD: oil and gas industry.
SUBSTANCE: configuration for obtaining of data transmission impulses in drilling fluid of a drilling column is offered which contains a sliding valve comprising a valve element, installed in the valve channel, hydraulically interconnected with the fluid medium flow channel in the drilling column to which the configuration is connected. The valve element is connected to the mechanism performing reciprocating movement, containing the balance weight, the driven cranked device and the sliding element making the sliding connection between the cranked device and the balance weight. Besides, the configuration contains the sliding element connected through the rotary hinge with the cranked device, it is fastened to the balance weight for rotation around the valve axis and is radially sliding with reference to the balance weight, so the rotation of the cranked device results in rotary reciprocating movement of the balance weight and, therefore, of the valve element around the valve axis for obtaining the data transmission impulses in drilling fluid.
EFFECT: improved reliability and efficiency of signal transmission through hydraulic communication path.
