      <abstract xml:lang="ru">
        <p>Современные методы расчета пневматических молотков ос­новываются на предположениях, что рабочие процессы их рав­новесны, а массообмен при наполнении и опорожнении рабочих полостей цилиндра происходит в соответствии с закономер­ностями установившегося течения сжатого воздуха.</p>

      <abstract xml:lang="en">
        <p>Modern methods of calculation of pneumatic hammers are based on the assumption that their working processes are equilibrium, and the mass exchange at filling and emptying of the working cavities of the cylinder occurs in accordance with the regularities of the steady flow of compressed air.</p>
