摘要：

The authors discuss the issue of engineering a special gear to change the power fluid pressure in hydraulic fracturing of strong rocks. The article describes the operation of the gear on the basis of implemented laboratory tests, and proposes the ways of eliminating deficiencies. The size and shape of choke grooves for the careful switching of the control valve subject to the power fluid flow rate are determined. The hydraulic circuit of the jet-control slide-type valve is developed. It allows improved accuracy and precision of the valve switching.
