Abstract
The features of the schemes of hydraulic impact machines are analyzed. The requirements for hydrostatic machines used in automated drilling systems in the implementation of adaptive engineering processes are formulated. A design of hydraulic impact mechanism with an intermediate drain chamber and annular elastic valve is developed. A simulation model of the proposed hydraulic impact system is constructed and dynamics of the operating cycle is studied.
