Abstract
The article describes computer modeling of three options of pneumatic percussion unit in a circular impact machine. All options have similar construction diagrams and mechanical linkage parameters but different control of energy-carrier feed in a working chamber: valveless; with one or two circular elastic valves. The obtained data allow quantitative evaluation of operation of such systems given the accepted constraints for mechanical block.
