FIELD: machine building.
SUBSTANCE: set of invention relates to machine building and can be used in mining for breaking of monoliths, in construction and seismic survey. Precise and reliable starting of adjustable impact machine (AIM) results from reduction of working fluid flow-over between forward and reverse stroke chambers and control chamber, hence, the increase in the machine output as well as from expansion of its performances and applications. In compliance with AIM control device second version as compared to the first one, said control device does not incorporate the working fluid source nor throttle but comprises control unit and receiver connected with the chemical working fluid source, starting solenoid valve. Note here that said control unit is connected with the said pressure gage and starting solenoid valve connected with reverse stroke chamber.
EFFECT: higher efficiency and reliability of AIM.
