Using the simulation model, the occurrence of significant counter pressure to striker movement during the power stroke in hummers with a hydraulic back stroke chamber is shown. A device (spring pressure reducing valve) is proposed, which allows decreasing the pressure of resistance to the striker movement. The comparative energy characteristics of a hummer with such a device and machine with standard discharge are obtained, technical parameters of both machines are similar.
