Abstract

The invention relates to the field of machine-building, in particular to the apparatuses for control and adjustment of hydro-systems, and can be used in the drives of vibro-processors, test benches, building vibro-machines, etc. A generator of pressure pulses includes a module of valve of first stage in the body of which a shutoff element is installed with formation of pressure, support, control and discharge cavities, a module of valve of second cascade in the body of which tubular slide spring-loaded with a controlled spring and a pusher are installed, the cavities for supply and discharge of working liquid, pressure, discharge and control channels with controlled throttles installed therein. Between the modules of valves of first and second cascades a module of fine adjustment is installed. Coaxially with the valve-pilot in the body of module of valve of first cascade the second valve-pilot is uninstalled, with formation of the support, control and discharge cavities.
