Abstract
Article describes a design and the principle of operation of the hydraulic impact device, with automatic control for a new operating mode, depending on loading on the working tool. The idea is based on the analysis of various schemes of management of hydraulic hammers taking into account requirements for their control and regulation for various industries. Article contains the general description of structural and hydro- kinematical schemes of a hydraulic hammer with automatic control of frequency of influences depending on loading on the working tool. The objectives have to be achieved by introduction of the regulator of a stream of working liquid in the control unit. The main element of such regulator has to be connected with the shock block on the special channel. It will provide rotation of the internal valve with various speed depending on loading on the working tool of the shock block.
