Abstract

Generator of pressure pulses comprises of the module of the valve of first cascade, this is made as a four-line, two-position, automated hydro-distributor, controlled by the pressure of opening and closing the generator; module of the valve of the second cascade, this is made as two installed in coaxial positions shutoff elements, the inlet one – of a cup type, and the outlet one – of a mushroom type, with central axial reboring. Shutoff elements have tightened surfaces, turned towards each other, and form with the reborings of the housing of the generator cavities: the pressure one, discharge, working, over-valve, under-valve, of the pushing element, of opening and closing the outlet shutoff element. In the central axial reboring of the shutoff element there is installed cylindrical pusher of smaller diameter, and coaxially to it in the axial reboring of the housing of the module of the valve of the second cascade – cylindrical pusher of larger diameter. Module of fine adjustment is installed between the modules of the valves of the first and the second cascades and comprises of installed in parallel controlled throttle and back valve.
